Answer 1

• An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system.
• Energy enters the system through photosynthesis and is incorporated into plant tissue.
• By feeding on plants and on one-another, animals play an important role in the movement of matter and energy through the system.
• They also influence the quantity of plant and microbial biomass present.
• By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling.
• The term ecosystem was first used in 1935 in a publication by British ecologist Arthur Tansley.
