These fun and educational activities can also be found on the National Wildlife Week Posters, available from your state affiliate of NWF, the South Carolina Wildlife Federation. Conatct Sara to request posters. An exciting journey of science discovery is as near as your own backyard. Just one small square is alive with creepers and crawlers, lifters and leapers, singers, buzzers, climbers, builders, and recyclers. Every habitat is an ecosystem, a community formed of the plants and animals in relation to their environment.
Green plants are food producers.
Animals are consumers. Herbivores, which consume plant matter directly, are primary consumers. Secondary consumers, or primary carnivores, are those that devour primary consumers. Decomposers are life forms such as bacteria, fungi, and other microorganisms that break down the remains of other organisms, and thus return nutrients to the soil to be used by green plants. The sequence from green plant to secondary carnivore is the food chain.
