Question

decomposers are important in nutrient cycles because they— a. produce oxygen for plants b. prevent soil erosion c. turn nitrogen gas into proteins d. release stored nutrients back into the soil question 9 1 pts which process in the carbon cycle removes carbon dioxide from the atmosphere? a. respiration by animals b. decomposition of dead organisms c. photosynthesis by plants d. combustion of fossil fuels

Explanation:

1. Decomposers break down dead - organic matter. In the process, they release nutrients such as nitrogen, phosphorus, and potassium back into the soil, which is important for the nutrient cycle. Option A is incorrect as plants produce oxygen through photosynthesis, not decomposers. Option B is about the function of plant roots and other soil - stabilizing factors, not decomposers. Option C is the function of nitrogen - fixing bacteria, not decomposers.
2. Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. In this process, carbon dioxide is removed from the atmosphere. Respiration by animals releases carbon dioxide into the atmosphere. Decomposition of dead organisms also releases carbon dioxide. Combustion of fossil fuels releases a large amount of carbon dioxide into the atmosphere.

Answer:

1. D. Release stored nutrients back into the soil
2. C. Photosynthesis by plants
