Unusual aspects of different animals.
Ecology is the study of the relationships of organisms to their environment and to other organisms.
A major part of ecology is the energy flow through the ecosystem , or collection of populations and habitats. 1 Photosythetic plants capture light energy and store it in the form of carbohydrates, fats, and proteins. We can call plants producers as a result. A primary consumer is a plant-eating animal, and a secondary consumer eats these primary consumers. This food chain is a flow of energy in the form of nutrients from one to another.
