Question

If 10000Jof energy is emitted by the Sun, how much energy will be available to

the top carnivore of the food chain consisting of four trophic levels?

Answer 1

Answer:

1) If 10,000 joules of energy is available to the producer, then only 1000 joules of energy will be available to the primary consumer and only 100 joules of energy will be available to the secondary consumer.

Explanation:

2) The trophic level of an organism is the place it has in a food chain. A food chain is mostly made up of three trophic levels. However, some trophic levels have four trophic levels. An example is shown in the diagram.

→Primary producers which are plants that are autotrophs and belong to the first trophic level.

→Primary consumers are animals that belong to second trophic level and feed on plants. They are called herbivores.

→Secondary consumers feed on herbivores and belong to the third trophic level. They are called primary carnivores.

→Tertiary consumers feed on primary carnivores and belong to the fourth trophic level. They are called secondary carnivores.

Answer 2

Explanation:

According to the 10 percent law, only 10% of the energy is transferred to each trophic level from its lower trophic level. If 10,000 joules of energy is available to the producer, then only 1000 joules of energy will be available to the primary consumer and only 100 joules of energy will be available to the secondary consumer. The energy available with the tertiary consumer will be 10 joules of energy.
