Answer:

10 units

Explanation:

Energy is transferred from organism to organism in an ecosystem when they feed on one another. However, based on the pyramid of energy, only about 10% of energy is transferred from one organism to another because a bulk of energy (about 90%) has been lost to metabolic activities.

Energy moves from producers to consumers, each occupying trophic levels. If the first trophic level in an energy pyramid receives 1,000 units of energy from the sun,

- 10% of 1000units will be available for the second trophic level i.e. 10/100 × 1000 = 100units

- 10% of 100units will be available for the third trophic level i.e. 10/100 × 100 = 10units

Hence, 10units of energy is available for the third trophic level.

Answer: All of these are true (besides the one that says that none are true...).

Explanation:

The ecological succession is a slow change in the living community of the ecosystem along with the changes occurring in the non-living environment until the ecosystem attains stability.

The primary succession can be defined as the initial level of succession. This succession begins in the primitive environment. The soil develops after the weathering process of rocks.

The secondary succession begins in the region where life forms existed before and the area begin damaged by the catostrophic event like forest fire, earthquake and other type of calamities. Some remaining plant parts can give birth to the entire colony of plants.
