food pyramid
the top of the food pyramid gets its choice of food, but most of the energy is at the bottom
food chain
a clean clear way to show the flow of energy. everyone wants to be at the top of the food chain
food web
look confusing? a food web can show the complex interaction of energy flow within an ecosystem.
now, lets take a second to talk about the \flow of energy\ in an ecosystem (thats a fancy way of saying \who eats who\)
every organism has its position, or trophic level, within that ecosystem. that position determines who is the predator, and who is the prey. like i said, not everybody can be at the top of the food chain like me.
the organization of the different species can be shown in a few different ways. being the nice guy that i am, ive given you a few beautifully constructed examples.
now lets take a look at whos involved in this little game of \who eats who\:

1. ______—plants that can make their own food through photosynthesis. at the bottom of the food chain.
2. ______—plant eaters. they feed off of the producers, so they are one step higher on the food chain.
3. ______—meat eaters. they eat herbivores—or other carnivores—so they can be pretty high on the food chain.
4. ______—they dont play fair. these micro-organisms wait until other organisms die, and then feed off of their decay.
