Carnivores occupy second and third both tropic level in the food chain.why?
Answers
Answer:
A food chain is systematic hierarchical series that shows the sequential dependence of organisms on each other for food.
Trophic level refers to the hierarchical levels in an ecosystem or a food chain. It contains organisms that share the same function in a food chain and have similar nutritional relationship with the producers (primary source of energy).
The first trophic level in a food chain is occupied by the producers. These are the primary source of energy in a food chain.
The second trophic level in a food chain is occupied by the herbivores. These organisms feed directly on the producers. They are referred to as primary consumers.
The third trophic level is occupied by the carnivores. These organisms feed on the herbivores (second trophic organims). In the third trophic level are carnivores that only feed on the herbivores. They are referred to as secondary consumers.
The fourth trophic level is occupied by carnivores that feed on other carnivores. These carnivores are referred to as tertiary consumers.
The fifth trophic level is occupied by occupied by organism such as bacteria and fungi that decompose all other dead organisms.
Note: omnivores are animals that feed on both herbivores and producers (and at times carnivores as well). They can fall on fall on either the second, third or forth trophic level.
Explanation:
Answer:
Explanation:
Because first tropic level is occupied by producers and second tropic level is occupied by herbivores animals or first stage consumers
