Question

What is biodiversity? Mention the causes of loss of biodiversity (Any three)

Answer 1

Hint: Biodiversity here bios define life and diversity means forms. Biodiversity is the grouping of several types of environment, animals adapted to diverse weathers and the atmosphere with their communication. Biodiversity is defined as the degree of variation of life forms or the variety of living organisms present in any ecosystem.

Complete answer:
Biodiversity is the variability of life on earth. It is an amount of the differences at the hereditary, classes and environment levels. Every animal in ecology has a vital part to production. Due to this biodiversity becomes a very important aspect, because if even the smallest of the organism drops out from the biodiversity, then all the ecological food chains, food cycles, and food webs, etc. are disturbed and altered.
This puts extra burden on certain other classes and looms their destruction. If the biodiversity of a part is not conserved, then the whole environmental equilibrium will get distressed.

Causes of biodiversity loss:
• Habitation Loss and Fragmentation: This is the most imperious motive full of life beings and plants to exclusion. The most expressive case of atmosphere disaster is created from humid rainforests. The Amazon rain timberland protecting likely an enormous number of animal crowds is being cut and unfurnished.
• Over abuse: People are dependent on nature for nutrition and harmless houses; though, when lacking swipes to greed, it prompts over abuse of regular resources.
• Co-elimination: At the point when animal categories end up wiped out, the plant and creature species related to it must move toward becoming extinct.

Additional information:
Biodiversity is the presence of a variety of life on earth. It can be measured on three levels: genetic, species and ecosystem level.

Other main causes of biodiversity:
• The loss of habitat will result in fragmentation of habitat leading to small habitat with few organisms.
• The main reason for decrease in biodiversity is overpopulation, global warming, deforestation, and pollution.

Note: The term biological diversity was defined scientifically in 1980 by Thomas Lovejoy. Biodiversity is the variation of the organisms in any given region. Hence, it is the variation of the biotic components only. The term biodiversity does not have everything to organize with the abiotic constituents.
