What abiotic factors can limit the size of populations in an ecosystem?
There are many abiotic and biotic factors that can limit populations in ecosystems. 2. Abiotic factors include natural disturbances or environmental conditions such as temperature. a. A forest fire can greatly reduce a population.
Both abiotic and biotic factors determine where a species can live. A limiting factor is any factor that places an upper limit on the size of a population. Limiting factors may be biotic, such as the availability of food, or abiotic, such as access to water.
- In general, biotic factors are the living components of an ecosystem and are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.

- The maximum number of individuals that can be supported sustainably by a given environ- ment is known as its 'carrying capacity'. For most non-human species, the concept is quite simple. If carrying capacity is exceeded, the population declines because its environment can no longer support the excess numbers.
The largest population size that an ecosystem can sustain is called its carrying capacity. Carrying capacity is always limited by the resources that are available to a population. In a natural ecosystem, population growth is limited by factors such as the amount of living space, food, sunlight, and water.
- Examples of limiting factors include competition, parasitism, predation, disease, abnormal weather patterns, natural calamities, seasonal cycles and human activities. In terms of population growth, limiting factors can be classified into density-dependent factors and density-independent factors.
- Density-dependent factors are most often biotic variables. Biotic variables are all of the living organisms within an ecosystem. Abiotic variables, all of the non-living things in an ecosystem, such as weather, natural disasters, and sunlight, usually affect a population in the same way, regardless of the density.
- Logistic growth is when growth rate decreases as the population reaches carrying capacity. Carrying capacity can be defined as maximum number of individuals in a population that can be supported by the environment.
Limiting factors may be physical or biological. The limiting factor also causes competition between individuals of a species population. For example, space is a limiting factor. Many predators and prey need a certain amount of space for survival: food, water, and other biological needs.

- Definition of limiting factor. 1 : the factor that limits the reaction rate in any physiological process governed by many variables. 2 : the environmental factor that is of predominant importance in restricting the size of a population. lack of winter browse is a limiting factor for many deer herds.
- Temperature and rainfall can limit population growth. Harsh weather conditions can prevent food production and less people can be supported. Series of predictable changes that occur in a community over time. Series of changes that occur in an area where no soil or organisms exist.
