What is Biodiversity? How Many Types of Biodiversity Are There?
Biodiversity refers to all living organisms that exist on earth and cooperate for sustainable living. Irrespective of size and species, biodiversity includes plants, animals, microorganisms, etc.
What Is Extinction?
It is the elimination of a specific kind of organism or group of organisms. A particular species is believed to go extinct the moment its last individual dies. Typically, overhunting, captivity or drastic climate change is among the major reasons for the extinction of animals.
Why Is Conservation Important?
All living organisms are interdependent and must coordinate with one another to sustain biodiversity. Through conservation, we can preserve wildlife, protect endangered species, conserve water and protect soil from erosion.
Why should we conserve biodiversity?
An area with a higher species abundance is considered to have a more stable environment than one with a lower species abundance. We might also claim that biodiversity is necessary when we consider our level of dependence on the environment. For our diverse needs, we rely directly on various plant species. Similarly, we depend on numerous animal and microbe species for various reasons.
Biodiversity is being lost because of habitat loss, resource overexploitation, climatic changes, pollution, invasive exotic species, illnesses, and hunting, among other factors. It is critical to protect biodiversity since it provides us with several economic and ethical benefits as well as aesthetic value.
Describe a few ways in which biodiversity benefits humans.
We get benefited economically from a wide range of entities, including:
What factors determine whether a species is threatened?
To classify a species as threatened, the following criteria must be met:
What is the difference between endemic and exotic species?
Exotic species are introduced into one geographical area from another, whereas endemic species are native species that are only found in a particular geographical area.
What can be the consequences of the loss of biodiversity?
Consequences of loss of biodiversity are:
