What is one potential impact of decreasing genetic diversity?

Both inbreeding and drift reduce genetic diversity, which has been associated with an increased risk of population extinction, reduced population growth rate, reduced potential for response to environmental change, and decreased disease resistance, which impacts the ability of released individuals to survive and …

For which of the following reasons do small isolated islands have a greater rate of species extinction than larger less isolated islands *?

Extinction is greater on islands isolated due to the unlikelihood of immigration and as it is opposite to the island close to the mainland and competition is more in isolated islands.

What are the main factors that contribute to loss of biodiversity?

Reason for Loss of Biodiversity

  • Habitat destruction. Habitat destruction is a major cause of biodiversity loss.
  • Invasive Species.
  • Over-exploitation of Species.
  • Global Warming and Climate Change.
  • Pollution.
  • Human Overpopulation.
  • Natural Calamities.
  • Genetic Pollution.

What are the factors that affect diversity?

[Google Scholar]). Secondary, diversity includes mainly factors such as socio-economic status, education, religion, geographical affiliation and marital status (Sweetman, 2004. (2004). Gender, Development and Diversity.

What factors can affect living organisms in a community?

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

What are 3 abiotic factors that affect an ecosystem?

Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature. Water (H2O) is a very important abiotic factor – it is often said that “water is life.” All living organisms need water.

What factors is most likely to decrease the stability of an ecosystem?

Factors affecting stability: Disturbance frequency and intensity (how often and what kind of tillage) Species diversity (intercropping or rotations), interactions (competition for water and nutrients from weed species), and life history strategies (do the species grow fast and produce many seeds or slow with few seeds)

What are 5 examples of limiting factors?

Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.

How many limiting factors are there?

They are (1) keystone species, (2) predators, (3) energy, (4) available space, and (5) food supply. In biology, the term limiting factor is defined as an environmental factor or variable that has the capacity to restrict growth, abundance, or distribution of a population in an ecosystem.
