Food Chain Definition Ecology. The food chain is a series of living things which are linked to each other because each. How about all of the above?
A food chain almost always begins with a green plant (producer) which is eaten by an animal (consumer). In scientific terms, a food chain is a chronological pathway or an order that shows the flow of energy from one organism to the other. Photosynthesis is only the beginning of the food chain.
A trophic cascade often results in dramatic changes in ecosystem structure and nutrient cycling.
Energy is not created or destroyed. Trees and shrubs → giraffe → lion (). See ecology ecology, study of the relationships of organisms to their physical environment and to one another. A food chain represents only one dimension of food or energy flow through an ecosystem and shows a simple relationship between components.
