Photosynthesis and cellular respiration are chemical processes that demonstrate one way matter is cycled through the ecosystem. Neither matter nor energy can be created or destroyed, and both move through systems. Matter is cycled through a system, and energy flows through a system using inputs and outputs.
To better understand photosynthesis & respiration…
LET’S BREAK IT DOWN!
Photosynthesis is the chemical process in which carbon dioxide and water combine using energy from the Sun to make sugar and oxygen. Photosynthesis is used by plants and other organisms, such as algae and cyanobacteria, to synthesize (make) their own food.
The chemical process in which stored energy is broken down so it can be used by an organism to survive when there is no food source available. Cellular respiration is a multi-step process with different amounts of energy being produced at each step. Both plants and animals go through cellular respiration to access and use stored energy.
