Give any two examples of indigenous and foreign vegetation
Answers
Answer:
From an evolutionary perspective, an indigenous species is one which is evolved from its ancestor in the location in which it is found. Meaning, on an evolutionary time scale of millions of years, the species should have been present in an ecosystem.
An exotic species is one which is introduced into an ecosystem from outside. This usually involves human intervention.
For example, brinjal is indigenous to India. It developed in the region and was domesticated around 7000 BC in the Indus Valley civilization. While tomatoes are native to South America and were introduced in the rest of the world by human travellers.
PS. Some definitions of exotic species only include species with are considered dangerous for an ecosystem. This is not entirely correct. Any species introduced in an ecosystem can be called exotic.
