B. [tex]1\%[/tex]
C. [tex]10\%[/tex]
D. [tex]100\%[/tex]



Answer :

In an ecosystem, energy transfer between trophic levels follows ecological efficiency rules. Typically, only about 10% of the energy available at one trophic level is transferred to the next level. This phenomenon is known as the 10% Rule.

Let's apply this rule to the scenario where a deer consumes grass:
- The grass represents the primary producers in this food chain.
- The deer is the primary consumer, feeding on the grass.

According to the 10% Rule, when the deer consumes grass:
1. The deer will acquire approximately 10% of the energy present in the grass.

Therefore, the percentage of energy that the deer will acquire from the grass is:
[tex]\[ 10\% \][/tex]

So, the correct answer is:
[tex]\[ \boxed{10\%} \][/tex]
