Question

in an ecosystem, a deer consumes grass. what percentage of energy will the deer acquire from the grass?
0.1%
1%
10%
100%

Explanation:

In an ecosystem, the 10% energy transfer rule (also known as Lindeman's trophic efficiency rule) states that typically, only about 10% of the energy from one trophic level is transferred to the next trophic level. Grass is a producer (first trophic level), and the deer is a primary consumer (second trophic level). So the deer will acquire about 10% of the energy from the grass. The other options (0.1%, 1%, 100%) do not align with this ecological energy transfer principle.

Answer:

C. 10%
