What does it mean if the biodiversity index of an ecosystem is closer to 1?

The closer the diversity index is to 1, the more diverse and healthy it is. This is a very simplified version of diversity index. The more accurate versions are called the Simpson and Shannon Indexes.

Is 1 a high biodiversity index?

It has a very low biodiversity index of 1/300, or 0.003. … The biodiversity index here is high, 5/5 = 1.

Why is biodiversity important to ecosystems 1 point?

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. … Our tourism industry also depends on biodiversity .

What does a low biodiversity index mean?

Although it’s commonly used to measure biodiversity, it can also be used to gauge diversity differences of populations in schools, communities and other locations. The range is from 0 to 1, where: High scores (close to 1) indicate high diversity. Low scores (close to 0) indicate low diversity.

What does high or low biodiversity mean to an ecosystem which is best?

High biodiversity, with many species present, is good. It usually means that an ecosystem is healthy and relatively undisturbed by humans. Low biodiversity is characteristic of an unhealthy or degraded environment. A mown lawn in a city park is an example of an ecosystem with low biodiversity.

What does a high biodiversity index mean?

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)

How do you interpret the biodiversity index?

This figure would represent a community containing only one species. The higher the value, the greater the diversity. The maximum value is the number of species (or other category being used) in the sample. For example if there are five species in the sample, then the maximum value is 5.

Why is biodiversity important to ecosystems quizlet?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

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.

What do you understand by biodiversity explain the need of 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.

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 higher the value, the greater the diversity. The maximum value is the number of species (or other category being used) in the sample.

What is the biodiversity index of the ecosystem?

A biodiversity index is a scale of the diversity of plant and animal species at your study site. Biodiversty is a widely used tool for estimating the complexity, stability, and thus general health of an ecosystem.

How does low index of diversity affect the environment?

Loss of biodiversity appears to affect ecosystems as much as climate change, pollution and other major forms of environmental stress, according to results of a new study by an international research team. … Studies over the last two decades demonstrated that more biologically diverse ecosystems are more productive.
