What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

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 primary function of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, to facilitate the process of photosynthesis.

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2 (Carbon dioxide + Water + Light energy → Glucose + Oxygen)

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is one of the raw materials used in photosynthesis, which plants take in from the atmosphere to produce glucose.

What is ATP and its role in cellular respiration?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, produced during cellular respiration to provide energy for various cellular processes.

What happens to energy as it moves up the energy pyramid?

Back

As energy moves up the energy pyramid, approximately 90% of the energy is lost as heat or thermal energy, with only about 10% being transferred to the next trophic level.

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter, which is then passed through the food chain.

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis and cellular respiration are interconnected 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.
