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.
An example of a density-independent factor limiting population growth is a natural disaster, such as a wildfire or a severe drought. These events impact a population regardless of its size or density, leading to significant declines in numbers without being influenced by the population's current density. Other examples include climate changes or extreme weather events.
It is called a limiting factor.

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.

One limiting factor in bird populations is cats.
Drought is not a density-dependent factor limiting population growth. Density-dependent factors, such as predators, food availability, and living space, have effects that intensify as the population size increases. In contrast, drought affects all individuals in an area regardless of population density, thus classifying it as a density-independent factor.
