Question: Why is an ecosystem with high index of diversity?

An ecosystem with a high level of biodiversity is more resistant to environmental change and to human impacts. The Species Richness index is the most common type of biodiversity index. It is the number of different species present in an area. … The more species are present in a sample, the ‘richer’ the area.

Why is an ecosystem with high index of diversity more favorable?

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.

Why is it better to have a high index of diversity?

A high index value suggests a stable site with many different niches and low competition (high richness and evenness) A low index value suggests a site with few potential niches where only a few species dominate (low richness and evenness)

What makes an ecosystem have a high diversity?

A region with numerous interactions among organisms likely has a large number of species and high species biodiversity. If a region has high species biodiversity, it has a lot of genetic variability in the organisms that make up the ecosystem.

What ecosystem has high diversity index?

Two of the Most Diverse Ecosystems on Earth

Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.

What is the importance of species diversity to the ecosystem?

In a healthy ecosystem, diverse and balanced number of species exist to maintain the balance of an ecosystem. In an ecosystem, all the species depend on each other directly or indirectly. So to make a more efficient, productive and sustainable ecosystem, it is important to maintain high species diversity.

Why is high biodiversity important?

Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.

Is high or low diversity index better?

The value of this index also ranges between 0 and 1, but now, the greater the value, the greater the sample diversity. … The value of this index starts with 1 as the lowest possible figure. This figure would represent a community containing only one species. The higher the value, the greater the diversity.

Does a high diversity index always mean a habitat is healthy?

of a diversity index does not necessarily indicate health condition of the community..

What diversity index should I use?

The Shannon diversity index (1949) is the most commonly used. It expresses the relative importance of the number of abundant species in a given environment.

What is ecosystem diversity?

Ecosystem Diversity can be defined as the variety of different habitats, communities and ecological processes. A biological community is defined by the species that occupy a particular area and the interactions between those species.

Why do some ecosystems have more biodiversity than others?

Unique Climates and Conditions

One of the most significant and naturally occurring causes of differences in biodiversity across the world is differences in climate. … On the other extreme, moist, tropical zones like the Amazon rainforest support some of the highest levels of biodiversity in the world.

Which would you infer about an ecosystem with high species diversity?

Explanation: Biodiversity is a measurement of how many different types of organisms are found in an ecosystem. The higher the biodiversity means that the ecosystem can sustain (maintain) many different types of producers, consumers, and decomposers. This generally means that the area is healthy.

What are some examples of ecosystems with high biodiversity?

Some examples of ecosystems that are rich in diversity are:

  • Deserts.
  • Forests.
  • Large marine ecosystems.
  • Marine ecosystems.
  • Old-growth forests.
  • Rainforests.
  • Tundra.
  • Coral reefs.

What is an ecosystem What are examples of diverse ecosystem?

Grasslands, tundras, deserts, rainforests, terrestrial and marine ecosystems, are some examples of ecosystems that are diverse and contribute a lot to creating a well-balanced environment.

Why is high biodiversity advantageous over low biodiversity?

High biodiversity is advantageous over low biodiversity because ecosystems with high biodiversity are better able to remain at homeostasis and be…
