Structure-here
An ecosystem is like a molecular system in many ways. Each part plays a role in the whole, and each part of a molecular system can be compared to an ecosystem.
Atom- An atom is the smallest form of matter. An example of an atom is an element such as oxygen or nitrogen.
An atom is analogous to….
A population: a population is a group of organisms of the same species in the same area. For example- a group of deer in a forest is a population.

Molecule- A molecule is the bonding of several atoms together. In these bonds energy is held and can be transported from place to place inside a cell.
A molecule is analogous to…
A habitat: A habitat is a place where a population resides. There are many different types of habitats, and all kinds of different populations live in each one. For example, the marsh is a habitat.

Macromolecule- Macromolecule are larger forms of molecules. A macromolecule has a carbon chain. An example of a macromolecule is lipids/fats. A macromolecule is analogous to…
Communities: A community is all the populations living in a habitat. It is many different parts of the ecosystem, but does not include abiotic factors such as soil and water and wind. An example of a community is all the deer living in a forest.

Organelles: Organelles are the major organelles of a cell. They perform specific tasks in a cell. Without organelles the cell would not be alive. Some examples of organelles are the ER and the nucleus.
Organelles are analougous to…
A niche: a niche is a certain type of species custimized to fit a specific function in it's surroundings. For example: smaller birds have a niche in the fact that they use the upper branches of a tree. They custimize to their environment because the smaller tree branches protect them from attack by larger birds.

Cells: Cells are the smallest living organisms. They formed by all the parts mentioned above-atoms, molecules, macromolecules, and organelles. They can form more complex structures such as the organisms in a population.
Cells are analougous to…
Ecosystems: Ecoysystems are all the factors above together. It is a community, but also includes all the abiotic factors such as rainfall and wind. In this way all the factors that affect life in an area are included.

Both atoms and populations are building blocks for the rest of their respective systems. They provide materials neccesary to have a molecular or an ecosystem. Organelles and niches are both very similar as well. An organelle plays a very specialized part in the life of a cell. It has very specific functions that it must carry out for a cell to be able to survive. This is also true for a niche. A niche musit exist for each animal, otherwise, that animal has no purpose for the survival of the ecosystem. In this case, the animal will soon no longer be part of the ecosystem. A molecule is much like a habitat because it helps build for the next level in the system. A molecule is the basis for a macromolecule, while a habitat is a neccesary thing for a community to be able to populate. A macromolecule is like a community because they are both large scale pieces of their respective systems. The species in a community are a large amount of the raw materials that exist in an ecosystem, while macromolecules form most parts of the cellular system. A cell is like an ecosystem because all these things are anoulagous to each other, and an ecosystem carries out tasks very similar to the tasks that a cellular system carries out, although on a smaller scale.


Energy-here
Without the movement of energy and matter in a system, the system can not exist. All the parts of each system are designed to do just that. From the atoms that act as building blocks to the cell that is alive, the whole process is for the changing and transporting of energy and matter.
The atom in a cell is very basic form. It is the most basic form of matter, but even at this most basic level, it is used to create more complex things. Tape: An atom does not hold energy in it. It is neutrally charged and is merely a nucleus with protons and neutrons surrounded by electrons.
A molecule holds and can move energy around. It does this by forming bonds between atoms and other molecules and then (when the energy is needed) breaking those bonds back up. This allows energy to be transported from one area of a cell (or any other part of a living thing) and used in another area, a very important part of life. Tape: An example of a molecule is ATP, which holds energy. It holds 3 phosphates attached to it, and when energy is needed, one of these breaks off, making it ADP. This molecule can then go and receive another P from an organelle that creates them.
Macromolecules also do this, but they do it on a much larger scale. Instead of 5-10 bonds, a standard macromolecule has 50-100! This means that much more energy can be held in the bonds, and when those bonds are broken, much more energy is released. Tape: Macromolecules are also used for other tasks, such as protection of the cell. These can impede or help move matter around. Tape: A macromolecule includes a carbon chain. This carbon chain holds many bonds which are not broken ever, and this energy is not used in a transport of energy, however, sometimes pieces of the top of the molecule will break bonds and share energy that way.

Organelles are a very important part in the processing of energy. These change the energy from one form to another. They do this in many different ways. In plants, it takes oxygen and light to be able to do this, and the process is called photosynthesis. In an animal cell, it is done through respiration. Tape: Photosynthesis provides glucose to the aerobic and anaerobic respiration process. This process is used in plant cells. In animal cells, the Krebs cycle replaces this. All this is to change a smaller amount of energy into a larger amount by using materials readily available in the cell.

The cell itself is a very important part of the whole procedure. It uses all the parts, puts them together and turns it into a way of living! Tape: This is the whole package deal-the movement of energy all occurs within the cell. Some has to move outside the cell, but that is not generally true. Any energy that is needed or helps out is changed to the needed form within the cell. The cell moves other products outside, which is what will be discussed next.

A habitat provides a way for the other parts of an ecosystem to move around. It allows a place for all the parts to be. Tape: A habitat is a necessary part of an ecosystem that is used for transporting energy and matter through.

A population is another building block, but this time in an ecosystem instead of a cellular system. It holds energy within itself, and it is used, like a molecule, to move the energy around the system. Tape: A population is a very large group of organisms, each made of cells. In this way, there is lots of energy in the population, and can be move about in several ways. Things such as seeds can cling to other animals to move themselves and change the place a plant will be.

A community is a larger group of populations. If a population is like a molecule, then it makes sense that a community is like a macromolecule. Because a community is so much larger, it is much better able to move energy around. Tape: A community does the job of a population, but in mass quantities. There are hundreds of communities compared to one population, therefore matter and energy can be moved around much more. This process includes (as an example of an animal) eating plants, converting them to energy in the body, and releasing it in many ways, such as heat, fecal matter, and other ways. A plant cell then takes these energies and converts them back into something useful for the plant, which is then eaten again etc. All this allows changes in the ecosystem.

A niche is similar to an organelle. It performs a specific duty, and uses and returns energy to the ecosystem in doing so. Tape: A niche performs a specific task in an ecosystem. Because energy can not be created or destroyed, it is used by the specific task that the niche uses it for, and then it is returned to the system.

An ecosystem is the combination of all these factors and the energy transferred in this system is based on all of them. Tape: ?????

Matter--here
An atom is the basic part of mater, and can not be broken down, nor can it do anything by itself, it is just a basic piece. Tape: ????

Molecule helps move matter all over a cell. It forms bond with a piece of matter that it wishes to be moved and then move it to a different part of the cell. Tape: An example of this phenominon is clear in ATP-because the P is needed elsewhere in the cycle, it latches on and is later deposited where it is needed.

Macromolecules are much bigger, and once again they can move larger amounts of energy and matter. That is because they can spread it out more. Tape: The carbon chain in a macromolecule helps this. It evens out the top-heaviness. This is another way macromolecules are much like molecules.

Organelle-helps to move many different things around, from the code that defines who we are as human beings (called DNA) to the oxygen needed to make energy. Tape: The ER helps transfer and create proteins out of genetic info. Stored in the nucleus. All this and more are part of moving matter around.

Cells need to move things around to different parts of the body as well, such as blood cells, and many others. All this is built into a cellular system. Tape: How does this happen?

A habitat does not actually move any matter around, merely is there for the other parts of the ecosystem to use it for that purpose. Tape: A habitat is merely there, as it only includes (basically) the abiotic factors in the ecosystem.

Populations are a major mover of matter. They eat things and then defecate them, seeds and more attach to legs, they release seeds to the wind, and more. Tape: Populations can move things all over the habitat, and this a major source of matter througout the ecosystem.

Communities are all the populations powers of moving matter around put together. This means that everything that moves because of a living thing is because of the community's ability to move matter. Tape: The community does cause everything to happen in an ecosystem basically, at least on large scale terms. The earth being eaten by worms, the grass being eaten by deer, it all causes many different effects, and they are all part of this description.

A niche is a specialized part of the community. While the community may move everything as a whole, the niches fill in each specific part of the jobs. They cause things to be moved, and each animal has its niche to fill. Tape: A niche fills many specific jobs-from the transport of seeds to the feedback loop of plant eating, they all cause different things to happen.
