Give reason why a food chain cannot have more than four tropic levels |
|
Answer» is PASSED up a food chain or web from lower to higher trophic levels. This loss of energy explains why there are RARELY more than four trophic levels in a food chain or web. Sometimes there may be a FIFTH trophic level, but usually there's not ENOUGH energy left to support any additional levels. |
