Question

in a grazing food chain energy present at primary producer level is 1000j then what would be the energy at tertiary consumer level ?
1. 100j
b. 10j
c. 0.1j
d. 1j

Answer 1

Answer:

(D) 1 J

Explanation:

1J because we know that only 10% of the total energy is transffered from lower trophic levels to upper trophic levels.

so, at primary consumers level ---> 100J

at secondary consumers level ---> 10J

thus, at teritary consumers level ---> 1J
