Biodiversity is an indicator of the health of an ecosystem because the more biodiverse it is, the healthier it will remain. As organisms become endangered or extinct, links in the food webs in those areas are compromised.
What is a biodiversity indicator?
Biodiversity indicators are communication tools that summarize data on complex environmental issues. … They provide a framework for assessing a broad cross-section of issues fundamental to the conservation and sustainable use of biodiversity, and to the equitable sharing of the benefits from the use of genetic resources.
What are the major environmental indicators?
Five important global-scale environmental indicators are biological diversity, food production, average global surface temperature and atmospheric CO concentrations, human population, and resource depletion. Define sustainability and explain how it can be measured using the ecological footprint.
Is biodiversity a part of environment?
Biodiversity is the variety of life on Earth. This life, in all its shapes and sizes, occurs in the context of ecosystems: it relies on and interacts with other organisms and the physical environment. … But biodiversity is also a measure of the health of any ecosystem.
What are the 4 environmental indicators?
biological diversity, food production, average global surface temperature and carbon dioxide concentrations in the atmosphere, human population, and resource depletion. These key environmental indicators help us analyze the health of the planet.
What is biodiversity example?
It is the biodiversity at the most basic level. It includes all the species ranging from plants to different microorganisms. No two individuals of the same species are exactly similar. For example, humans show a lot of diversity among themselves.
Why biodiversity is an indicator?
Biodiversity is an indicator of the health of an ecosystem because the more biodiverse it is, the healthier it will remain. … Biodiversity supports ecological services including, purification of the water and air, pollination, prevention of erosion and the stabilization of CO2 levels.
What are the two indicators of biodiversity?

The state of species and ecosystems, such as the health of species or integrity of ecosystems.
How biodiversity is an indicator of sustainability?
Biodiversity is essential for sustainable development and human well-being. It underpins the provision of food, fibre and water; it mitigates and provides resilience to climate change; it supports human health, and provides jobs in agriculture, fisheries, forestry and many other sectors.
Which is considered as an indicator of environmental pollution?
ABSTRACT. Bioindicators are living organisms such as plants, planktons, animals, and microbes, which are utilized to screen the health of the natural ecosystem in the environment. They are used for assessing environmental health and biogeographic changes taking place in the environment.
What do you know about 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.
What are the environmental pollution indicators?
Examples of environmental, ecological, and biodiversity indicators can be found in many different organisms inhabiting many different environments. Lichens (a symbiosis among fungi, algae, and/or cyanobacteria) and bryophytes (mosses and liverworts) are often used to assess air pollution.
