O photosynthesis and respiration
O chemosynthesis and decomposition
O decomposition and combustion

Answer 1

Autotrophs make food through photosynthesis and chemosynthesis.

Step-by-step explanation:

Autotrophs, or organisms that can produce their own food, use two main processes to make food: photosynthesis and chemosynthesis.

Photosynthesis is the process by which autotrophs convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen. This process occurs in plants, algae, and some bacteria.

Chemosynthesis is the process by which certain bacteria and archaea use energy from chemical reactions to produce glucose. Unlike photosynthesis, chemosynthesis does not require light and can take place in environments where light is not available, such as deep-sea hydrothermal vents.
