Answers (1)

The answer is option (c) Steller’s sea cow is an extinct animal.

Explanation: An endemic species is one that exists only in a specific geographical area and is not found anywhere else. Parthenium, also known as carrot grass, is not native to India. It likely came to India as a contaminant in imported wheat from the USA. Parthenium is an invasive weed that grows quickly and harms native plants, disrupting the ecosystem it invades. Another non-native plant, Lantana, also competes strongly with local species. The African catfish is another non-native species that negatively impacts the growth of indigenous catfishes in our rivers.
