Question

in which ways is photosynthesis important to life on earth? check all that apply. makes food for all organisms adds oxygen to the atmosphere adds carbon dioxide to the atmosphere is a source of medicines and fibers is a source of building materials provides animal habitat breaks down waste materials done

Explanation:

• Makes food for all organisms: Through photosynthesis, plants (and some other organisms) produce glucose (a form of food). Other organisms either eat these plants (producers) directly or eat animals that have eaten plants.
• Adds oxygen to the atmosphere: A by - product of photosynthesis is oxygen. This oxygen is released into the atmosphere and is essential for the respiration of most aerobic organisms.
• Is a source of medicines and fibers: Many plants that perform photosynthesis are sources of fibers (e.g., cotton) and medicines (e.g., some plants used in traditional and modern medicine).
• Is a source of building materials: Plants (products of photosynthesis) can be used as building materials (e.g., wood from trees).
• Provides animal habitat: Plants (which rely on photosynthesis) form the basis of many habitats. For example, forests (made up of photosynthetic plants) provide shelter, food, etc., for a wide variety of animals.

• Adds carbon dioxide to the atmosphere: Photosynthesis actually takes in carbon dioxide from the atmosphere, not adds it.
• Breaks down waste materials: This is more related to the role of decomposers (like bacteria and fungi in some cases) rather than the direct role of photosynthesis.

Answer:

makes food for all organisms, adds oxygen to the atmosphere, is a source of medicines and fibers, is a source of building materials, provides animal habitat
