What two factors determine biodiversity?

Factors that affect biodiversity in an ecosystem include area, climate, and diversity of niches.

What are the two factors of biodiversity?

1. Biodiversity & Distribution of Life

  • Biotic, abiotic and human influences are all factors that affect biodiversity in an ecosystem.
  • Grazing and predation are biotic factors; pH and temperature are abiotic factors.
  • Biomes are the various regions of our planet as distinguished by their similar climate, fauna and flora.

What determines biodiversity?

Biodiversity is basically the variety within and among life forms on a site, ecosystem, or landscape. Biodiversity is defined and measured as an attribute that has two components — richness and evenness. Richness = The number of groups of genetically or functionally related individuals.

What are the factors affect biodiversity?

The numerous factors are responsible for the loss of Biodiversity (Figure 1) such as pollution, habitat loss, hunting, introduction of invasive species, overexploitation of preferred species, climate change, and natural disasters. Figure 1: The causes of Biodiversity loss.

What is diversity and biodiversity?

The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.

Does biodiversity include abiotic factors?

Biodiversity. The biosphere includes all of the biotic and abiotic factors of the Earth. The biotic factors are interdependant upon each other as well as upon the abiotic factors: the atmosphere, oceans, freshwater, soil, temperature and moisture.

What are 3 types of biodiversity?

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

What are the two measures of species diversity in an ecosystem?

Scientists measure biodiversity by using two measurement scales: species richness and species evenness.

What are three components of biodiversity?

Genetic diversity, species diversity and ecosystem diversity are three important components of biodiversity.

What defines biodiversity?

Biodiversity is all the different kinds of life you’ll find in one area—the variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural world. Each of these species and organisms work together in ecosystems, like an intricate web, to maintain balance and support life.

How is biodiversity measured?

Biodiversity is often measured as the species count in a given area, be it a single tree, an ecosystem, a landscape or region, or the planet as a whole. However, biodiversity may be measured in other ways. BIODIVERSITY MAY BE MEASURED AS GENETIC DIVERSITY.
