How+is+a+food+web+organized?+-+Questions

After completing the activity, answer the following questions in your journal.


 * 1) What would happen if the food chains or webs had no scavengers or decomposers?
 * 2) For most habitats, which description do you think is more accurate - a food chain or a food web? Why?
 * 3) What is a trophic level?
 * 4) Based on the food web interactions you just determined, why could it be a serious problem if a consumer organism that had no predators was introduced into the ecosystem? (This sometimes occurs when non-native organisms are released from captivity).
