As a marine biologist, the changes in food chain is valuable in detecting a problem in the environment. Take the assignment to a different level by introducing a disaster to the food chain. This could be a chemical spill, illness to a particular species, or a natural disaster. Have students predict what would happen support their answer. At the bottom of each food chain are the producers or autotrophs.
Producers are able to make their own food with sunlight.
Organisms that can't make their own food are called consumers or heterotrophs. Consumers must either eat producers to obtain energy or must feed on other producers. All organisms are tied to one another in a chain. Your assignment is to create a food chain that might be found in the bay of Corpus Christi. Use the pictures provided to make this web.
