Flow of energy definition biology
WebEnergy flow is, along with the cycling of nutrients, the defining ecosystem process. You can model how energy originally created by the sun would flow through an ecosystem using the model of a food chain. WebThe process of photosynthesis involves the absorption of CO 2 by plants to produce carbohydrates. The equation is as follows: CO 2 + H 2 O + energy → (CH 2 O) n +O 2. Carbon compounds are passed along the food chain from the producers to consumers. The majority of the carbon exists in the body in the form of carbon dioxide through respiration.
