Correct answer choice is:
D) Elements continuously cycle between the physical environment and living organisms.
Explanation:
Any nonliving matter that living things want is termed a nutrient. Carbon and nitrogen are parts of nutrients. Unlike energy, the object is converted into ecosystems. Decomposers deliver nutrients when they cut down dead organisms. When one organism eats a different organism, it takes all of its nutrients. Nutrients can also cycle out of an ecosystem. Falling leaves may be moved out of an ecosystem by a water. Decomposers cut down dead organisms into nutrients and carbon dioxide, which they respire into the air.
