What causes uniform distribution ecology?

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 factors cause a clumped distribution of organisms?

An area with an uneven distribution of food, water, moisture, temperature, or other resources can cause clumped dispersion. This pattern can also be caused by the formation of social groups based on protection or hunting. In plants, clumped dispersion is common when offspring fail to disperse from parent plants.

What are the possible reasons why populations are distributed in different manner?

The main factors determining population distribution are : climate, landforms, topography, soil, energy and mineral resources, accessibility like distance from sea coast, natural harbours, navigable rivers or canals, cultural factors, political boundaries, controls on migration and trade, government policies, types of …

Why are the species non uniformly distributed?

The non uniform distribution of species is result of different living factors (biotic factors) and nonliving factors (abiotic factors).

Why do penguins have uniform distribution?

Uniform distribution is observed in plants that secrete substances inhibiting the growth of nearby individuals (such as the release of toxic chemicals by sage plants). It is also seen in territorial animal species, such as penguins that maintain a defined territory for nesting.

How do biotic factors affect 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 are responsible for the distribution of plants and animals in India explain Class 9?

Answer: Relief (Land and soil) and Climate (Temperature, humidity, photoperiod and precipitation) are the factors which are responsible for the distribution of plants and animals in India.
