A
carrying capacity
B
limiting nutrient
C
limiting factor
D
growth factor
Explanation: 

Detailed explanation-1: -A limiting factor is anything that constrains a population’s size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.

Detailed explanation-2: -So a biotic or a biotic resource that cause population size is limiting factor that caused a decrease in population size is called us limiting factor.

Detailed explanation-3: -In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.

Detailed explanation-4: -Abiotic factors: These are the non-living factors whose imbalance will limit the population’s growth, such as water scarcity, air pollution, changing the temperature to adverse levels, harsh climate, and limited space.

Detailed explanation-5: -Density-dependent limiting factors cause a population’s per capita growth rate to change-typically, to drop-with increasing population density. One example is competition for limited food among members of a population.
