that's called a limiting factor (food is an example).
Abiotic factors refer to the non-living components of an ecosystem. An abiotic factor that can be a limiting factor for a coyote population is the lack of water, since it is essential for their survival.
Habitat itself is not considered a density-independent factor; rather, it is more accurately classified as a density-dependent factor. Density-independent factors, such as weather events or natural disasters, affect population sizes regardless of the population's density. In contrast, habitat quality and availability can influence population dynamics based on how many individuals occupy that space, making it density-dependent. Therefore, habitat plays a crucial role in shaping population interactions and survival based on density.
Severe weather is considered a density-independent factor because its effects on a population do not depend on the population's size or density. Events like hurricanes, floods, or droughts can impact all individuals in an area regardless of how many there are, leading to widespread mortality or displacement. This means that whether a population is large or small, severe weather can equally influence its survival and reproduction rates. Thus, it acts independently of population dynamics.

A drought is considered a density-independent limiting factor because it affects all individuals in a population regardless of their population density. It reduces the availability of water, impacting the survival and reproduction of organisms, leading to a decline in population size.
A limiting factor is a component of an ecosystem that restricts the population size of an organism. It can include factors like food, water, shelter, space, or competition for resources. When a limiting factor is in short supply, it can prevent a population from growing further.

Temperature is an abiotic factor that can affect the behavior and survival of organisms like robins and violets. Extreme temperatures can impact their ability to regulate body temperature, affect their metabolism, and influence their growth and reproduction.
There are quite a few biotic factors that affect the size of a population in an ecosystem. Grass is one of these factors.
