Summarize the similarities and differences between cellular respiration and photosynthesis in your own words. Include at least six sentences, explaining how these processes are interconnected and how they differ in terms of input, output, energy flow, and organisms involved. Also, discuss how these processes complement each other in the ecosystem to sustain life.

Cellular respiration and photosynthesis are fundamental biological processes that sustain life on Earth, and they are interconnected in the global energy cycle. Both processes involve the transfer of energy and matter; however, they operate in opposite directions. Photosynthesis, occurring primarily in plants, algae, and some bacteria, converts light energy into chemical energy stored in glucose molecules, utilizing carbon dioxide and water as inputs and releasing oxygen as a byproduct. In contrast, cellular respiration, which takes place in both autotrophs and heterotrophs, breaks down glucose molecules to release energy in the form of ATP, consuming oxygen and producing carbon dioxide and water as outputs. The key similarity lies in their reliance on ATP, which serves as the cellular energy currency, and both processes involve a series of enzymatic reactions. The major difference is that photosynthesis requires light energy to synthesize glucose and oxygen, whereas cellular respiration releases energy stored in glucose, making the processes essentially reverse of each other. These processes are tightly linked, with photosynthesis providing oxygen and glucose essential for respiration, and respiration producing carbon dioxide and ATP necessary for various cellular functions. Together, they form a vital cycle that maintains atmospheric balance and supports life through biochemical energy flow across ecosystems (Campbell & Reece, 2005; Berg et al., 2006).
