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.

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

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 !

How abiotic factors affect the distribution of living 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.

IMPORTANT:  What are the two kinds of disturbances that change ecosystems give an example of each?

How do biotic factors influence the distribution of organisms?

Biotic factors

They can also influence the distribution of organisms in an ecosystem. grazing – too little leads to dominant plants outcompeting other species, too much reduces species numbers overall. Both decrease biodiversity. predation – a reduction in predators can lead to an increase in prey.

What factors 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?

Biotic factors such as soil bacteria, plant life, top predators, and polluters can all profoundly shape which organisms can live in an ecosystems and what survival strategies they use.

What factors affect the distribution of plants and animals?

Abiotic factors affecting distribution of plants and animals

  • Rocks. the rocks of the lithosphere have to be weathered and the soil has to be formed before a plant to grow. …
  • Food. …
  • Air. …
  • Water. …
  • Nutrients. …
  • Soil. …
  • Temperature. …
  • Light.

Why are plants and animals affected by abiotic factors?

The abundance of organisms in an ecosystem and their distribution is affected by abiotic factors. These are factors that are non-living. light is required for photosynthesis , and plant species have evolved for optimum growth in the light available in their climate or habitat.

What are abiotic and biotic factors?

Biotic and abiotic factors are what make up ecosystems. Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere.

IMPORTANT:  How is biodiversity related to human food security?

How do abiotic and biotic factors affect organisms in an ecosystem?

Abiotic factors affect the ability of organisms to survive and reproduce. … Biotic factors are living things that directly or indirectly affect organisms within an environment. This includes the organisms themselves, other organisms, interactions between living organisms and even their waste.

How biotic factors affect living organisms?

Biotic factors are defined as the living components or factors that affect an ecosystem or other organisms living in that ecosystem. Bacteria that live inside the intestine of an animal act as biotic factors that have acquired the role of helping with the proper digestion of the food in the intestine.

What are the factors affecting the distribution of organisms?

Factors affecting species distribution

  • climatic factors consist of sunlight, atmosphere, humidity, temperature, and salinity;
  • edaphic factors are abiotic factors regarding soil, such as the coarseness of soil, local geology, soil pH, and aeration; and.
  • social factors include land use and water availability.
