The CARBON CYCLE AND GREENHOUSE EFFECT. The cycling of matter in ecosystems. Energy flows but nutrients cycle. The molecules in an organism will eventually be found in another organism. Recycling is fundamental for sustainability Prevents accumulation of wastes
On the chemical level, the cycle of growth, reproduction, death, and decay of organisms is a continuous process of taking atoms from the environment, assembling them into living organisms (growth), disassembling them (decay) and repeating the process.
