African catfish was introduced in Indian water. It is an example of
1 Disturbance and degradation
2 Coextinctions
3 Alien species invasions
4 Over exploitation
Explanation:
The recent illegal introduction of the African catfish Clarias gariepinus for aquaculture purposes is posing a threat to the indigenous catfishes in our rivers, it is an eg. of alien species invasion .

What is the reason many species like Steller's sea cow and passenger pigeon are becoming extinct?
1 Overexploitation by humans
2 Pollution
3 Habitat loss
4 Competition from introduced species
Explanation:
Many species like Steller's sea cow and passenger pigeon have been driven to the brink of extinction. This is due to overexploitation of a species by humans, which reduces the size of its population and it becomes vulnerable to extinction.

Which of the following is the most important cause for animals and plants being driven to extinction?
1 Habitat loss and fragmentation
2 Drought and floods
3 Economic exploitation
4 Alien species invasion
Explanation:
Habitat loss and fragmentation is the most important cause driving animals and plants to extinction. eg: Loss of tropical rainforest reducing the forest cover from \(14 \%\) to \(6 \%\).
