Question

6. What parts of this cycle show how energy is conserved in living systems?

A. Combustion and decomposition
B. Fossil fuels and carbon dioxide in the atmosphere
C. Cellular respiration and photosynthesis
D. Photosynthesis and combustion

Answer 1

Option (A)

Step-by-step explanation:

Both decomposition and combustion are chemical processes of converting complex material into much simpler compounds. Decomposition is a natural process. When animals and plants die and excrete, their bodies and other waste material are broken down into smaller pieces and ultimately to simpler forms of matter. This process is known as decomposition.
