Question

1. notice the populations decrease as you go from the bottom of the food chain to the top. why do you think this is so?

Explanation:

Energy transfer in a food chain is inefficient. Producers at the bottom capture energy from the sun. As energy moves up the food chain through consumers, only about 10 - 20% of the energy is passed on to the next trophic level. Higher - level consumers need more energy, so there must be fewer of them to sustain the energy flow.

Answer:

Because energy transfer in the food chain is inefficient and only a small percentage of energy is passed from one trophic level to the next, meaning higher - level consumers require more energy and thus there are fewer of them.
