how cool are food chains!



The food chain is a very important and interesting topic. A food chain is a chain that expresses organisms and what their food habits are. A food web is many different food chains collided and mixed in one. There are three types of consumers: herbivores which only eat vegetation, carnivores which only eat meat, and omnivores which eat both. A food chain starts wit a producer such as a plant. Then a consumer such as a grasshopper, this is called a primary consumer. Primary consumers are usually herbivores. Then usually its a larger organism, which eats the primary consumer which is known as the secondary consumer. Secondary consumers are usually carnivores or omnivores, such as a frog. Next comes a tertiary consumers, then so on and so forth. The end of the food chain is conquered by organisms which are called decomposer which literally decompose other dead organisms and return them to the soil. An example is a mushroom. So a food chain is producer---> primary consumer---> secondary consumer-----> a tertiary consumer---> decomposer.
