a. List the different kinds of organisms that can be found in your selected ecosystem.
b. Identify the structure and function of the main organs in at least two of the organisms found in your selected ecosystem, and indicate why they are best suited for that environment.
c. Label the three major types of organisms that live in your selected ecosystem as follows: "P" for producers, "C" for consumers, and "D for decomposers.
d. Name the three types of consumers: herbivores, carnivores, and omnivores within your selected ecosystem.
e. List the food chain(s) associated with your selected ecosystem. For each organism in the food chain, address the following items:
1) Name of plant or animal
2) What it eats
3) What eats it
4) How it adapts to the ecosystem
f. Identify potential hazards that might impact the stability of your selected ecosystem (e.g. environmental pollution).

Below are notes that will guide you in developing your own food web. They are not intended to be used as your work, but to aid you in understanding and to guide you in completing your own assignment.

In a food chain, energy is lost with every level of consumption. The sun is the initial source of energy. Plants absorb some of the sun's energy. Some of the sun's energy is lost, (reflects back into space, etc). Organisms that eat the plants receive some of this energy. However, some of the energy is lost in this process as well. The predator organism that consumes the plant-eating organism receives only some energy. This is because the organism that ate the plants used up a lot of the energy they consumed by ...
