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: Photosynthesis produces glucose (food) which is the base of the food chain. Herbivores eat plants (producers that perform photosynthesis), and carnivores eat herbivores.
• Adds oxygen to the atmosphere: The by - product of photosynthesis is oxygen. This oxygen is released into the atmosphere and is essential for aerobic respiration in most organisms.
• Is a source of medicines and fibers: Many plants that perform photosynthesis are sources of medicines (e.g., aspirin from willow bark) and fibers (e.g., cotton from cotton plants).
• Is a source of building materials: Wood from trees (which perform photosynthesis) is a common building material.
• Provides animal habitat: Plants (that perform photosynthesis) form the basis of many habitats. For example, forests provide habitat for a wide variety of animals.

Photosynthesis does not add carbon dioxide to the atmosphere (it takes in carbon dioxide). And breaking down waste materials is more related to decomposers (like bacteria and fungi) 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
