Ex-situ conservation is not responsible for biodiversity loss, rather it is a method of conservation of biodiversity. It conserves selected rare plants/animals in places outside their natural homes.
Which of the following is responsible for biodiversity loss?
Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming.
What is the main cause of loss of biodiversity?
Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.
What are the main causes of biodiversity loss Mcq?
The four reasons include Loss of habitat and fragmentation, Over-exploitation of species, Invasion of alien (new) species and Co-extinctions.
What are some examples of biodiversity loss?
On this page:
- Massive Extinctions From Human Activity.
- Declining amphibian populations.
- Reptiles threatened by climate change, deforestation, habitat loss, trade.
- Dwindling fish stocks.

- Inland water ecosystems.
- Loss of forests equates to a loss of many species. …
- Misuse of land and resources.
What are the causes of loss of biodiversity class 12?
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.
What are the 6 threats to biodiversity?

Which of the following is not the biodiversity hotspot region?
The correct answer is The Eastern Ghats. According to Conservation International, a region must fulfill the following two criteria to qualify as a hotspot: The region should have at least 1500 species of vascular plants i.e., it should have a high degree of endemism.
Where is biodiversity loss the worst?
A study by 16 global conservation organizations found that the biodiversity crisis is most acute in freshwater ecosystems, with a rate of decline double that of oceans and forests. Global populations of freshwater fish are collapsing from anthropogenic impacts such as pollution and overfishing.
What are the 5 factors that affect biodiversity?
Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
