Question

36 one food chain for the ecosystem represented in the pyramid is grass->insect->bear. if you were to place the bear into the energy pyramid, the bear would go on level __ and have ____ amount of energy available to it.

a
b
c
a) b; an intermediate
b) a; the greatest
c) a; the least
d) c; the least

Explanation:

Step1: Identify Trophic Levels

In an energy pyramid, the base (level C) is producers (Grass), then primary consumers (Insect, level B), then secondary consumers (Bear, level A).

Step2: Energy Flow in Pyramid

Energy decreases as we move up trophic levels (only ~10% transferred). So top level (A) has least energy.

Step3: Match Bear's Position

Bear is a secondary consumer (third in chain: Grass→Insect→Bear), so it's at level A, with the least energy.

Answer:

C. A; the least
