Please answer ASAP! My teacher just assigned this today, and it is due in an hour..I have about 30 questions to finish :( Why are organisms in lower parts of the food chain not affected but organisms at the top of the food chain are?

the organisms at the top of the food chain are effected because theyre bigger and the need more food and prey to survive. for example sharks, if fish arent thriving because they arent eating enough from the bottom of the food chain, the sharks cant eat them and the sharks will starve.

Explanation:

The organisms at the bottom of the food chain have a tendency of reproducing faster. (unlike the top of the food chain). Don't think that the the organisms at the bottom of the food chain are not as important though! Everything is important in any food chain!
