What is the term for the maximum population size that an environment can sustain indefinitely?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Carrying capacity.
Carrying capacity refers to the maximum population size of a species that an environment can support indefinitely without being degraded. It depends on factors like availability of resources (food, water, shelter), space, and the ability of the environment to absorb waste. If a population exceeds its carrying capacity, it may lead to resource depletion, environmental stress, and eventually a population decline or collapse.
Other Options:
-
Pioneer species: First organisms to colonize a barren or disturbed ecosystem.
-
Biotic potential: The maximum reproductive capacity of a species under ideal conditions.
-
Ecological niche: The role and position a species has in its environment, including how it obtains resources.
