Answer 2

Answer:

(b)biosphere

Explanation:

• The biosphere is the part of the earth where living things exist. It encompasses all living things living in the lithosphere, atmosphere, and hydrosphere.
• The biosphere has existed for about 3.5 billion years. The biosphere’s earliest life-forms, called prokaryotes, survived without oxygen. Ancient prokaryotes included single-celled organisms such as bacteria and archaea.
• Some prokaryotes developed a unique chemical process. They were able to use sunlight to make simple sugars and oxygen out of water and carbon dioxide, a process called photosynthesis.
