Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems.
It encompasses diversity within species, between species, and of ecosystems. Let’s explore the various types of biodiversity:
There are several definitions and terms used to describe different aspects of biodiversity:
Abiotic: Refers to the non-living components of an ecosystem, such as air, water, and soil.
Biotic: Refers to the living components of an ecosystem, including plants, animals, fungi, and microorganisms.
Endemic: Refers to species that are native to a specific geographic area and are found nowhere else in the world. These species are often vulnerable to habitat loss and climate change.
Extinct: Refers to a species that no longer exists. Extinction can occur naturally or as a result of human activities, such as hunting, habitat destruction, or pollution.
Endangered: Refers to species that are at risk of becoming extinct in the near future. This can be due to factors such as habitat loss, poaching, or pollution.
Flora: Refers to all the plant species found in a particular region or ecosystem.
Fauna: Refers to all the animal species found in a particular region or ecosystem.
Hot Spots: Refers to areas with exceptionally high levels of biodiversity that are also under threat from human activities. These hotspots are important for conservation efforts due to their unique and diverse ecosystems.
