Question

Study of the global ecosystem becomes easier when it is broadly divided into ............ basic categories.

• A. 3
• B. 2
• C. 4
• D. 5

Answer 1

The correct option is B 2

An ecosystem can be visualized as a functional unit of nature, where living organisms interact among themselves and also with the surrounding physical environment. Since this system is too much big and complex to be studied at one time, The study of the global ecosystem becomes easier when it is broadly divided into 2 basic categories, namely the terrestrial and the aquatic. Forest, grassland, and desert are some examples of terrestrial ecosystems, pond, lake, wetland, river, and estuary are some examples of aquatic ecosystems.

So, the correct answer is '2'.
