Question

Suppose 10, 000 units of energy are available at the level of the grasses. What is the total number of energy units available by the time energy reaches the coyote?

Question 7 options:

10,000 units


1,000 units


100 units


10 units

Answer 1

Answer:

10 units

Explanation:

Coyote is tertiary consumer which feed on secondary consumer such as snake. Grasses are the producer which has 10,000 units of energy. We know that only 10% of energy is passed from one trophic level to another and the remaining 90% is lost as  a form of heat energy. So only 1000 unit of energy is transferred to primary consumer. From primary to secondary consumer, only 100 units of energy is transferred and from secondary to tertiary consumer only 10 units of energy is transferred.

Answer 2

The total number of energy units available by the time energy reaches the coyote is 10 units. So, the correct option is D.

What do you mean by Energy unit at trophic level?

Energy units at the trophic level may be defined as the amount of energy at each trophic level decreases as it moves through an ecosystem.

As we remember the 10% law given by Lindeman, which states that 10 percent of the energy at any trophic level is transferred to the next trophic level. Since Coyote belongs to the tertiary consumer it feeds on secondary consumer-like snakes. Producers have the energy of 10000 units, which may be received by the primary consumer with 1000 units, this energy gets transferred to the secondary consumer with 100 units, and finally to the tertiary consumer with 10 units.

Therefore, the total number of energy units available by the time energy reaches the coyote is 10 units.
