Answer: The CARRYING CAPACITY of a particular population in an ecosystem is defined as the maximum population size that the environment can support indefinitely.
Explanation:
Population size is important as it affects the survival of a given species in a habitat. A small population may be easily wiped out by events such as fires, diseases, unfavorable climatic changes and so on. A large population stands a better chance of surviving dangers and unfavorable conditions.
The carrying capacity of a population in an ecosystem can show some changes due to the following factors:
--> migration of organisms to other habitats
--> invasion or colonization by new species and
--> increase or decrease in birth rates and death rates.
These factors operate during:
--> seasonal climatic changes,
--> changes in food availablity,
--> breeding periods and
--> unfavorable natural events such as fires and droughts.
