NEET BIOLOGY

Detailed explanation-1: -For a given region, carrying capacity is the maximum number of individuals of a given species that an area’s resources can sustain indefinitely without significantly depleting or degrading those resources.

Detailed explanation-2: -Carrying capacity is the maximum population size of a species that the environment can sustain indefinitely given available resources.

Detailed explanation-3: -A population that grows very quickly and exceeds its environment’s carrying capacity is said to overshoot its environment’s capacity. A catastrophic dieback, when the population plummets to well below its maximum, usually follows an overshoot.

Detailed explanation-4: -An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition. Indicator species can signal a change in the biological condition of a particular ecosystem, and thus may be used as a proxy to diagnose the health of an ecosystem.

Detailed explanation-5: -Carrying capacity is the maximum number of a species an environment can support indefinitely. Every species has a carrying capacity, even humans. However, it is very difficult for ecologists to calculate human carrying capacity. Humans are a complex species.
