Quick Answer: What biotic factors affect the distribution of organisms?

How biotic factors and abiotic factors affect the distribution of organisms?

The biodiversity in ecosystems is affected by the following three factors: Biotic: Biotic factors are the interactions between the living things in an ecosystem. … Extremes of an abiotic factor can reduce the biodiversity of the ecosystem. For example, ecosystems with a very low temperature tend to have low biodiversity.

What are the factors that affect the distribution of organisms?

The biodiversity and distribution of organisms within an ecosystem is due to both abiotic (non-living) and biotic (living) factors.

Abiotic factors

  • light intensity.
  • temperature.
  • soil pH.
  • soil moisture.

What are three biotic factors that can affect an organism?

Explanation: 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.

What are the biotic factors affecting population?

Biotic factors refer to the living or once-living organisms in an ecosystem and their impacts such as predation, competition, food supply, human impacts and parasites. Environmental factors such as rainfall, climate, predators, shelter and food availability can change.

What are 3 biotic and abiotic factors?

The biotic factors refer to all the living beings present in an ecosystem, and the abiotic factors refer to all the non-living components like physical conditions (temperature, pH, humidity, salinity, sunlight, etc.) and chemical agents (different gases and mineral nutrients present in the air, water, soil, etc.)

What is a biotic factor to a organism?

A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.

What are 10 biotic factors in an ecosystem?

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

How do abiotic factors affect the distribution of organisms?

Inorganic nutrients, soil structure, and aquatic oxygen availability are further abiotic factors that affect species distribution in an ecosystem. The same is true for terrestrial factors, such as wind and fire, which can impact the types of species that inhabit regions exposed to these types of disturbances.
