Yes
No (correct)
Sometimes
Depends on the ecosystem

What are plants called in an ecosystem?

Match the following statements with their correct justifications:

Carnivores occupy the second trophic level in the food chain. = Incorrect. According to the energy transfer law, only 10% of energy is transferred from one trophic level to the other. The flow of nutrients in an ecosystem is considered to be a ‘one way’ transport. = Incorrect. The energy that is captured by the producers does not revert back to the Sun and the energy transferred to the herbivores. Plants in an ecosystem are called primary consumers. = Incorrect. The producers convert solar energy into chemical energy in the form of organic compounds. According to the energy transfer law, only 10% of energy is transferred from one trophic level to the other. = Correct. This is the reason why the statement about carnivores occupying the second trophic level is incorrect. Signup and view all the answers

Match the following terms with their correct definitions:

Producers = Convert solar energy into chemical energy in the form of organic compounds. Primary consumers = Derive their nutrition from the producers. Energy transfer law = States that only 10% of energy is transferred from one trophic level to the other. Carnivores = Do not occupy the second trophic level in the food chain.

Match the following concepts with their correct explanations:

Energy flow in an ecosystem = The energy that is captured by the producers does not revert back to the Sun and the energy transferred to the herbivores. Trophic levels = The position that an organism occupies in a food chain. 10% energy transfer = The reason why the energy captured by producers does not revert back to the Sun. Producers = Organisms that convert solar energy into chemical energy. Signup and view all the answers

Match the following terms with their correct roles in an ecosystem:

Carnivores = Receive energy from the herbivores in the food chain. Producers = Capture solar energy and convert it into chemical energy. Herbivores = Derive their nutrition from the producers in an ecosystem. Energy transfer law = Describes the amount of energy transferred from one trophic level to the other.
