2. carbon cycle
3. oxygen cycle
4. nitrogen cycle

pls frds pls give the answer pls

Answer 1

Oxygen cycle most likely includes sunlight,photosynthesis and respiration.

- Oxygen cycle is an environmental process where the oxygen is taken from the atmosphere and replenished again in the environment. This whole process continuously goes on in a cyclic way to maintain the oxygen balance in our environment.

- This cycle includes photosynthesis and sunlight because green plants produce oxygen by photosynthesis in the presence of sunlight.

- And this produced oxygen is consumed by the animals for their respiration.

Answer 2

Carbon and Oxygen cycle.

Explanation:

Sunlight, photosynthesis and respiration is included in the carbon cycle and oxygen cycle.

Oxygen cycle: The oxygen cycle is the cycle where in animal respiration atmospheric oxygen is converted to carbon dioxide and in photosynthesis  it is regenerated by green plants.

Carbon cycle: The carbon cycle is the cycle in which carbon moves from the atmosphere into an organisms and then goes back into the atmosphere.
