There are two different food chains in this example: 1. Spinach --> goat --> human --> tiger
2. Spinach --> goat --> tiger
Analyze whether the tiger is at the same level and whether it obtains the same amount of energy in both the food chains.
A.
In the first food chain, tiger stands at a secondary consumer level whereas in the second food chain, it stands at primary consumer level; hence energy obtained in the second food chain is more than in the first.
B.
In the first food chain, tiger stands at a tertiary consumer level whereas in the second food chain, it stands at secondary consumer level; hence energy obtained in the second food chain is more than in the first.
C.
In both the food chains, tiger stands at a tertiary consumer level, because tiger is always a tertiary consumer; hence it obtains same amount of energy in both food chains.
