Question

Name any four major cause for loss of biodiversity​

Answer 1

• 1) Habitat loss and fragmentation- This is the most important reason causing the extinction of plants and animals. The habitats of various plants and animals are destroyed by uncontrolled human activities such as deforestation, mining, urbanization, etc. Due to these activities, the movement of migratory animals is affected and the genetic exchange between populations decreases leading to a declination of species.
• 2) Overexploitation- Many species extinctions in the last 500 years were due to the overexploitation and overhunting of various plants and animals by humans. Most industrial fisheries are either fully or overexploited, and the impacts of overharvesting are coupled to destructive fishing techniques that destroy habitat.
• 3) Alien species invasion- A declination or extinction of indigenous species is caused by the accidental or intentional introduction of non- native species into a habitat. Example: Introduction of Nile perch in Lake Victoria in Kenya led to the extinction of more than two hundred species of native fish in the lake.
• 4) Co-extinction- In a habitat, on species is connected to the other species in an intricate network. The extinction of one species causes the extinction of the other species. Example: The extinction of the host will cause the extinction of its parasites

Answer 2

So,I am telling you 5 points
(1)-Climate change
(2)-Deforestation and habitat loss
(3)-Overexploitation
(4)-Invasion species
(5)-Pollution
