Question

What do you understand by biodiversity? How can you say variations are present in them?

Answer 1

Hint: The term ecosystem can be described as the structural and functional unit of environment where the different living organisms interact with each other and the surroundings. It can be said that an ecosystem is a chain of interaction between organisms and their environment. Various different types of species are found to be present in an ecosystem.

Complete answer:
In an ecosystem, there is a huge variety of different species present. The term biodiversity explains the richness and variety of life on earth. It is the most important and complex characteristic of the earth. Biodiversity helps life to sustain on the earth and it represents variation among the plants, animals, and microorganisms species.
The number of different organisms and their relative frequencies in an ecosystem included in the biodiversity which also shows the organization of organisms at different levels.
Mainly there are three different types of biodiversity found in nature and they are genetic biodiversity, species biodiversity, and ecological biodiversity. Species diversity shows a variety of different types of species found in a particular ecosystem. It is biodiversity at the most basic level. Genetic diversity means the variations among the genetic resources of the organisms. The genetic constitution of each species differs from each other. And an ecological diversity defines the variations in the plant and animal species and their connection by food chains and food webs.
So, in biological diversity different various types of flora and fauna present in an ecosystem along with the surrounding environment.
The term biodiversity was first coined in 1985. It is one of the most important systems both in natural and artificial ecosystems. It trades with the variety of species in nature and the biosphere. Biodiversity has great ecological and economic significance. It gives the human being good nourishment, housing, fuel, clothing, and several other resources. It also has a great benefit to tourism. Thus, it is very important to have a good knowledge of biodiversity for a sustainable livelihood.

Note: The term biodiversity means the variety of living species on Earth where different types of plants, animals, bacteria, and fungi are included. The Earth has a rich biodiversity that is so rich and with an enormous variety of life that many species have not discovered yet while several species are being threatened with extinction due to human activities. Biodiversity introduces a togetherness between the different species and forms of life and their variability.
