rewatch

Explanation:

• The option "It only includes living things" is incorrect because the biosphere also includes the non - living components (like air, water, soil) that organisms interact with.
• "An individual organism" is wrong as the biosphere is not a single organism but a large - scale system.
• "The smallest unit of living things" is incorrect as the smallest unit of living things is a cell, not the biosphere.
• "Everywhere on Earth where organisms live" is correct. The biosphere encompasses all the regions of the Earth (land, water, atmosphere) where living organisms can be found, along with the abiotic factors in those regions.

Answer:

D. Everywhere on Earth where organisms live. (assuming the options are labeled A, B, C, D in order)
