Photosynthesis, Cellular Respiration, Carbon Cycle Review

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose (sugar) using carbon dioxide and water, releasing oxygen as a byproduct.

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

What is the carbon cycle?

Back

The carbon cycle is the process through which carbon is exchanged between the atmosphere, land, water, and living organisms, involving processes like photosynthesis, respiration, decomposition, and combustion.

What is decomposition in the carbon cycle?

Back

Decomposition is the process by which bacteria and fungi break down dead organic matter, returning carbon to the soil and atmosphere.

What is the significance of producers in the carbon cycle?

Back

Producers, like plants, are essential in the carbon cycle as they convert carbon dioxide into organic matter through photosynthesis, providing energy for other organisms.

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis and cellular respiration are complementary processes; photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.

What is the process of transpiration?

Back

Transpiration is the process by which water is absorbed by plant roots and then evaporated from the leaves, playing a role in the water cycle and helping to draw nutrients from the soil.
