In an ecosystem, a deer consumes grass. What percentage of energy will the deer acquire from the grass? 0. 1% 1% 10% 100%.
katen-ka-za [31]

In an ecosystem, the energy is transferred between the organisms participating in the food webs from producers and consumers.

The percentage of energy transferred to the deer after feeding on the grass is 10%.

The 10% law of the energy states that:

1. The food chain at each trophic level passes or transmits only 10% of the energy and 90% of the energy is lost as heat.

2. The amount of energy at each trophic level decreases, such that the producers if consuming the 100 J of energy, the deers or primary consumers at the first trophic level will have only 10% of the energy.

Thus, the deer will possess only 10% of the energy at each trophic level, following the 10% law.

The correct answer is Option C.
