Answer 1

The biosphere is the outermost part of the planet's shell — including air, land, surface rocks and water — within which life occurs, and which biotic processes in turn alter or transform. From the broadest geophysiological point of view, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere (rocks), hydrosphere (water), and atmosphere (air). This biosphere is postulated to have evolved, beginning through a process of biogenesis or biopoesis, at least some 3.5 billion years ago.

Answer 2

The biosphere is all of the parts of the Earth where things live. It includes three main parts:

1. The lithosphere includes all the land ecosystems.
2. The hydrosphere includes all the water ecosystems.
3. The atmosphere includes all the air-related ecosystems.

Answer 3

The biosphere is just the whole earth. I don't understand what you need to answer. A biosphere is a collection of ecosystems, ecosystem is a collection of communities, communities are a collection of populations, all populations are made of one organism, organisms consist of organ systems, organ systems are made of tissues, tissues are made up of cells, cells are made of molecules that form organelles, and molecules are made of atoms. Cells are the smallest living unit b/c they have the ability to reproduce. Biosphere is the largest and it encompasses all living things on earth, including things like rocks and the atmosphere. I think this is all right, correct me if i'm wrong with the order.
