Matter and Energy Transfer

Describe the role of producers, consumers, and decomposers in energy transfer within an ecosystem.

• Producers convert water into energy, consumers obtain energy by consuming rocks, and decomposers break down living organisms and release toxins into the ecosystem.

• Producers convert carbon dioxide into energy, consumers obtain energy by consuming air, and decomposers break down soil and release harmful chemicals into the ecosystem.

• Producers convert moonlight into energy, consumers obtain energy by consuming stars, and decomposers break down plastic and release pollutants into the ecosystem.

• Producers convert sunlight into energy, consumers obtain energy by consuming producers or other consumers, and decomposers break down dead organisms and waste, releasing nutrients back into the ecosystem.
