Explanation:
Believe it or not, _ENERGY_ within an ecosystem is not transferred back and forth between all levels. Energy begins with the SUN and flows in one direction to PRODUCERS to CONSUMERS and, finally, to DECOMPOSERS.
A FOOD WEB represents all the possible paths for energy to flow within an ecosystem, whereas a FOOD CHAIN represents just one path. When drawing a diagram of a food web, you always draw the arrow in the direction of ENERGY FLOW. For example, an arrow from a PRODUCER to a CONSUMER.
Organisms at all trophic levels eventually die. MICROORGANISMS such as bacteria and fungi, process the stored energy in dead plants and animals and transfer part of it to the soil that the plants will use as nutrients, and the energy cycle continues.
