Question: What is a biotic factor that might affect the size of a population in an ecosystem?

Which is a biotic factor that affects the size of a population in a specific ecosystem group of answer choices?

Biotic factors that a population needs include food availability. Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths. A limiting factor determines the carrying capacity for a species.

What factors affect the size of populations within an ecosystem?

Carrying capacity, or the maximum number of individuals that an environment can sustain over time without destroying or degrading the environment, is determined by a few key factors: food availability, water, and space.

Which biotic factor affects the number of animals in a population?

The availability of food is a major factor in how many animals live in an ecosystem .

How can biotic and abiotic factors affect the size of a population?

The carrying capacity depends on biotic and abiotic factors. If these factors improve, the carrying capacity increases. … If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.

What factor affect population growth?

Population Growth Rate

The two main factors affecting population growth are the birth rate (b) and death rate (d). Population growth may also be affected by people coming into the population from somewhere else (immigration, i) or leaving the population for another area (emigration, e).

What are the 7 biotic factors?

Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.

What biotic factors can limit a population size?

Limiting factors are those things in an ecosystem that restrict the size, growth, and/or distribution of a population. Biotic or biological limiting factors are things like food, availability of mates, disease, and predators.

What are the 4 limiting factors of an ecosystem?

The common limiting factors in an ecosystem are food, water, habitat, and mate. The availability of these factors will affect the carrying capacity of an environment. As population increases, food demand increases as well. Since food is a limited resource, organisms will begin competing for it.
