grass starts with 30,000 kcal of energy. a cheetah would acquire kcal of energy after it ate a zebra that had consumed the grass.

grass starts with 30,000 kcal of energy. a cheetah would acquire kcal of energy after it ate a zebra that had consumed the grass.

Answer

Explanation:

Step1: Recall energy - transfer rule

In a food chain, only about 10% of the energy is transferred from one trophic level to the next. Grass is a producer (first - trophic level), zebra is a primary consumer (second - trophic level), and cheetah is a secondary consumer (third - trophic level).

Step2: Calculate energy at zebra level

The zebra, as a primary consumer eating the grass, gets 10% of the grass's energy. So the energy the zebra gets is $30000\times0.1 = 3000$ kcal.

Step3: Calculate energy at cheetah level

The cheetah, as a secondary consumer eating the zebra, gets 10% of the zebra's energy. So the energy the cheetah gets is $3000\times0.1=300$ kcal.

Answer:

300
