Question

identify the cycle described. this nutrient is cycled between living things and the soil. plants absorb this nutrient and it into organic compounds through assimilation. animals eats the plants and pass it along the food chain from one organism to another. when the animal dies, it decomposes and returns the nutrient back to the soil. the nutrient can also enter the soil through weathering and 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. 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. done

Explanation:

The first description matches the nitrogen cycle where nitrogen is cycled between living things and soil, bacteria convert it to a usable form, plants take it up and incorporate it into proteins, and animals get it from plants and return it to soil upon decomposition. The second description about plants taking in a nutrient during photosynthesis and animals releasing it during respiration describes the carbon - cycle.

Answer:

First cycle: Nitrogen cycle
Second cycle: Carbon cycle
