1. what products are created by the process of photosynthesis?

a. the suns light and energy
b. oxygen and carbohydrates

d. carbon dioxide and water

Explanation:

1. Atoms are the basic units of matter and the smallest units that maintain the chemical properties of an element. Lipids are a type of organic molecule. Compounds are substances formed from two or more elements. Molecules are groups of atoms bonded together.
2. Proteins, nucleic acids, carbohydrates, and lipids are large molecules, so they are called macromolecules. Solutions are mixtures. Elements are pure substances. Hydrocarbons are a type of organic compound.
3. The geosphere is made of all the rock above and below Earth's surface. The lithosphere is the rigid outer layer. The hydrosphere is all the water. The atmosphere is the layer of gases.
4. Humans are part of the biosphere, which includes all living things. The geosphere is rock. The hydrosphere is water. The atmosphere is gas.
5. Nutrients are the matter that organisms require for life processes. Legumes are a type of plant. Decomposers break down dead matter. Fertilizers are used to help plants grow.
6. Photosynthesis produces oxygen and carbohydrates. The sun's light and energy are inputs. Phosphorus and nitrogen are elements. Carbon dioxide and water are inputs.

Answer:

1. A. atoms
2. D. macromolecules
3. B. geosphere
4. C. biosphere
5. D. nutrients
6. B. oxygen and carbohydrates
