1.What are the two main divisions of the Earth's surface?
2.Discuss the organisms found in biosphere?

Dear student,

1. The two main divisions of the Earth's surface are continents and ocean basins. Mass landmasses are known as continents where the huge water bodies are known as ocean basins.
2. The biosphere is that stratum of the Earth's surface where living organisms can exist. Biosphere has both the living and non-living things which are found at the centre of different Earth’s parts like lithosphere, atmosphere, hydrosphere. The organisms found in the biosphere are aquatic and marine animals like different fish, sharks, turtle, terrestrial animals like cats, lions, elephants, monkeys, birds, etc.
