Best answer: What are the biotic factors that influence the size of a population?

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 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.

What are the five main biotic factors?

Like all ecosystems, aquatic ecosystems have five biotic or living factors: producers, consumers, herbivores, carnivores, omnivores, and decomposers.

Which is a biotic factor that affects population size quizlet?

The environment limits population growth by changing birth and death rates. The factors affecting population size and growth include biotic factors such as food, disease, competitors, and predators and abiotic factors such as rainfall, floods, and temperature.

How biotic factors affect abiotic factors?

The abiotic factors will define which organisms are able or not to live in a specified place. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controling the biotic factors of an environment. Hope it helps you !

What are 3 biotic limiting factors?

Biotic or biological limiting factors are things like food, availability of mates, disease, and predators.

What type of factor has an increasing impact as the population size increases?

Answer: Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.
