✔ Carbon cycleNitrogen cyclePhosphorus cycle Plants take in this nutrient when they perform photosynthesis. An animal eats the plant and uses its carbohydrates for energy. The animal releases the nutrient back into the atmosphere during respiration.
Carbon cycle✔ Nitrogen cyclePhosphorus cycle Bacteria in the soil converts this nutrient into a usable form. Plant take up the usable nutrient through the soil and assimilate it into proteins, making it part of the plant. An animal eats the plants, and the nutrient becomes part of the animal. When the animal dies, it decomposes, returning the nutrient back to the soil.
