300 kJ. the zebra got 3,000. it used some and left 300 kJ

Answer:

300 KJ

Explanation:

As per the given details following food chain is formed -

Grass ---> Zebra -----> Cheetah

In a food chain, all the organism belong to a trophic level. The amount of energy passed on from one trophic level is just [tex]10[/tex]% of the energy at its previous trophic level.

By this concept, when zebra eats the grass, only [tex]10[/tex]% of energy of grass is transferred to zebra.

Thus, the energy obtained by zebra after eating grass [tex]= \frac{10}{100} * 30,000[/tex]KJ

[tex]= 3,000[/tex] KJ

When cheetah eats zebra , [tex]10[/tex]% of energy of zebra is transferred to Cheetah.

Thus, the energy obtained by Cheetah after eating zebra [tex]= \frac{10}{100} * 3,000[/tex]KJ

[tex]= 300[/tex] KJ
