What is common to Lantana, Eichhornia and African catfish?

a. All are endangered species of India.

b. All are keystone species.

c. All are mammals found in India.

d. All the species are neither threatened nor indigenous species of India

Answers (1)

The answer is option (d) All the species are neither threatened nor indigenous species of India.

Explanation: Lantana camara, Eichhornia crassipes, and the African catfish (Clarias gariepinus) are exotic invasive species in India that threaten local ecosystems and contribute to the extinction of native species. Lantana camara, native to the American tropics, has reduced the availability of native forage plants for wild herbivores. Eichhornia crassipes, known as water hyacinth or the "terror of Bengal," can overtake water bodies, depriving local communities of essential resources. The African catfish competes with native fish for nutrients and resources, further destabilizing the local aquatic ecosystem.
