stira [4]

Answer:

Thousands of species is an example of biodiversity.

Explanation:

Biodiversity is the short term for biological diversity which was coined by E.O. Wilson. Biodiversity refers to all the species of plants (flora) and animal Kingdom (fauna) present on the Earth. It covers different types of ecosystems present in a well-defined area whether it be terrestrial or aquatic and the genetic variability within a species.

The variety of crops and livestock present on Earth have played a great role in human development. Without them, life would not be possible. That’s why it is our moral duty to conserve our biodiversity. If we preserve it for our future generations, we will survive. If they are overused or misused, the entire food chain would perish.
