Quizplus · Accepted Answer

The biosphere refers to all living organisms found on Earth, including humans, animals, plants, and microorganisms. It encompasses all the ecosystems and habitats where life is found, including the land, oceans, and atmosphere. Therefore, the biosphere is the sum total of all life on Earth. The lithosphere is the solid outermost layer of the Earth, the mantle is the layer between the crust and the core, and the atmosphere is the layer of gases surrounding the Earth. While these all play important roles in the functioning of the biosphere, they do not encompass all of life on Earth.
