To accomplish survival, a living organism requires a zone of survivability. In science they call this zone of survivability the biosphere. The biosphere is that environmental zone wherein a living organism can meet its needs and act to survive.
Life on earth can be divided into three general classes – these are the plants, the animals, and we humans. These three classes of life each require a different biosphere to meet their needs.
Plants need sunlight, water, carbon dioxide from the air, and adequate minerals from the soil. Plants are able to grow and reproduce by utilizing sunlight in the process science calls photosynthesis. Photosynthesis allows plants to create organic tissue utilizing energy directly from sunlight.
Animals lack the plants' power of photosynthesis. They cannot utilize sunlight to create organic tissue. They must ingest either plant or animal tissue which they then digest to release chemical energy and molecular nutrients. They further need water and oxygen from the air instead of carbon dioxide.
Humans share animal body and like the animals lack the power of photosynthesis. We too must ingest plant or animal tissue. And, we too need water and oxygen.
The biosphere for plants must therefore provide sunlight, carbon dioxide, water, and minerals. It must also be some shelter from environmental extremes. It must not be too hot or too cold.
The biosphere for the animals, and for our human bodies must provide food either plant or animal tissue, oxygen, and water .
