Recycling of chemical nutrients from the atmosphere and soil through producers, consumers, and decomposers back to the environment

2

Exchange of energy

One - way flowof energy through an ecosystem, entering as sunlight, converted to chemical energy by producers, passed on to consumers, and exiting as heat
