1. The document discusses the interaction between habitats, with a focus on photosynthesis. Key terms defined include glucose, carbon dioxide, oxygen, respiration, and cell. 2. It explains that plants use photosynthesis to convert carbon dioxide and water into glucose and oxygen using energy from sunlight. Chlorophyll in the leaves absorbs light and gives leaves their green color. 3. The process of photosynthesis allows plants to gain energy without eating food, as animals do. Plants use sunlight to power the chemical reaction that produces glucose for energy and releases oxygen as a byproduct.

5. What Is oxygen?
What is something that's invisible, has no taste or smell, and
doesn't make a sound--but you couldn't live without it?
Oxygen, of course! Oxygen is the eighth element on the
periodic table of elements, where it's represented by the
letter O. An element is the simplest form of matter there is--it
can't be broken down into any simpler parts.
