-photosynthesis
-chemosynthesis
Explanation:
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.
hope it helps:)
Creating a proton gradient across the thylakoid membrane in higher plants uses cyclic electron flow (CEF), which primarily serves two purposes: (1) producing ATP and balancing the ATP/NADPH energy budget; and (2) defending photosystems I and II from photoinhibition.
ATP and NADPH are produced by noncyclic electron transport. The single product of cyclic electron transport was ATP. Both steps are required by a plant to produce the required amount of ATP for the Calvin Cycle. The electrons are released by photosystem I and then brought back into the system during cyclic photophosphorylation. However, in non-cyclic photophosphorylation, the electrons that the photosystems emit do not come back.

13). Atoms are the basic unit of matter
14). Elements (pure substances, one type of atom) and Compound (made up of two or more types of atoms)
16). Chemical change
17). If a rock is changed or broken and stays where it is, it is weathering. If pieces of pebbles and soil from the rock are moved by natural forces, it is erosion
Hope that helps
