10 Questions
Which trophic level do carnivores occupy in the food chain?
Third trophic level
Is the flow of nutrients in an ecosystem considered to be 'one way' transport?
No
What are plants called in an ecosystem?
Producers
According to the energy transfer law, how much energy is transferred from one trophic level to the other?
10%
Does the energy captured by producers revert back to the Sun?
No
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.
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.
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.
Match the following statements with their correct explanations:
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. 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. Plants in an ecosystem are called primary consumers. = Incorrect. The producers convert solar energy into chemical energy in the form of organic compounds. 10% of energy is transferred from one trophic level to the other. = Correct. This is the reason why the statement about the flow of nutrients being 'one way' is incorrect.
