Question

2. About how much of the energy contained originally in the grass is usable by the

lion?
A 10 kg
B 0.1 kg
c 1 kg
OD 5 kg

Answer 1

The correct option is B. 0.1

Step-by-step explanation:

According to the information provided in the question, a zebra eats 10 kg of grass. This zebra is then eaten up by a lion.

Researched have shown that approximately 10% of an energy transfer is made from one trophic level to another. The rest of the energy is lost.

Hence, 10 kg of grass will give :

10/100× 10

= 1% or 1 kg of energy to the zebra

The grass will give

1/100× 10

= 0.1% or 0.1 kg of energy to the lion.
