Factors that decrease population growth can be defined as environmental stress including limitations in food, predation, and other density-dependant factors

A factor that limits the growth of a population.
"In an ecosystem, a limiting nutrient constrains the growth of organisms much like how a limiting factor, such as food availability or predation, constrains the population growth of a species."
Temperature is a density-independent limiting factor for rainbow trout. Changes in water temperature can directly impact the metabolism, growth, and behavior of rainbow trout, regardless of the population density or size.
It is called a limiting factor.
the effect of human disturbance on animal populations is
The number of moose on the island is a density-dependent limiting factor for the wolves. As the moose population fluctuates, it directly impacts the available food source for the wolves. If the moose population decreases, the wolves will face food scarcity, potentially limiting their population growth.
limiting factor
One limiting factor in bird populations is cats.
The diseases will kill off the animals and plants living there which means that it is limiting the growth of the population.
Density-independent limiting factors are factors that do not rely on the population and are aspects of an environment that limit its growth like hurricanes, fires, and deforestation.
