Ecology: Ecological succession

Ecological succession is the process of change in the species present in an ecosystem over time.

There are two types of succession:

• Primary succession,, where an area that hasn't had any life before begins to be colonized, such as a new island.

,

• Secondary succession,, where there is a disturbance, such as a fire, that removes the organisms living in that area.

The changes in plants depend on changes in the soil and interactions with other organisms, such as competition for light with other plants and feeding from herbivores.

On the other hand, the changes in animals depend on sources of food and predation interactions.

This means the correct answer would be A. Food availability.
