You asked: What 2 factors determine biodiversity?

What are two factors to consider what determining the biodiversity in an ecosystem? Biodiversity is defined and measured as an attribute that has two components — richness and evenness.

What two factors determine biodiversity?

Factors that affect biodiversity in an ecosystem include area, climate, and diversity of niches. Which human activities threaten biodiversity? Human activities can also threaten biodiversity. These activities include habitat destruction, poaching, pollution, and the introduction of exotic species.

What are the main factors that affect biodiversity?

Major threats to biodiversity are:

  • Habitat destruction/Deforestation.
  • Introduced and invasive species.
  • Genetic pollution.
  • Over exploitation.
  • Hybridization.
  • Climate change.
  • Diseases.
  • Human over-population.

How is biodiversity assessed?

When scientists assess an area’s biodiversity, they look at species richness (how many different species there are) and relative abundance (the number of organisms each species has). … Others have made their mark as invasive species. They survey aquatic creatures in the water, and make censuses of trees in the forest.

What do you know about biodiversity?

Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of ecosystems.

What are 4 types of biodiversity?

Four Types of Biodiversity

  • Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other. …

  • Ecosystem Diversity. …
  • Functional Diversity.

What are 3 ways to measure biodiversity?

How Do Scientists Measure Biodiversity? Scientists use several methods to measure biodiversity. These include canopy fogging, quadrat sampling, transect sampling, and netting. The method used depends on the types of organisms ecologists are counting and on the habitat.

Why should we assess biodiversity?

Assessing areas of high biodiversity plays a vital role in determining key areas for conservation and establishing conservation priorities. … The more critical role an area or system plays for ecosystems, the more value it has in positively influencing biodiversity.

What are the 3 types of biodiversity?

Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity.

How does biodiversity determine the function of ecosystems?

It has been shown that biodiversity of an area has a large impact on the ecosystem stability of that area. Areas with high levels of species and genetic diversity are likely to have a more complex ecosystem, with a variety of food webs and biotic interactions.
