AP BIOLOGY

Detailed explanation-1: -Which of these organisms is involved in the carbon cycle? Which step is it involved in? What is happening during this process with this organism? Bacteria; nitrogen fixation, ammonification, nitrification, denitrification; convert atmospheric N to usable N, convert N to ammonia, etc.

Detailed explanation-2: -Plants absorb carbon from the environment in photosynthesis and return it in respiration. Animals obtain their carbon by eating plants; they release carbon in respiration. Micrororganisms (such as fungi and bacteria) return carbon to the environment when they decompose dead plants and animals.

Detailed explanation-3: -Carbon Cycle Steps Carbon present in the atmosphere is absorbed by plants for photosynthesis. These plants are then consumed by animals and carbon gets bioaccumulated into their bodies. These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.

Detailed explanation-4: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-5: -Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them.
