Ecology: Ecology is the scientific study of interactions among organisms or groups of organisms with their environment. It encompasses understanding how living entities such as plants, animals, and humans relate to and depend on their surroundings for survival. According to V.S. Saravana Mani (date unspecified), ecology involves examining these interactions to comprehend the functioning of natural systems.
Ecosystem: An ecosystem is a fundamental unit within ecology, defined as a community of different species interacting with each other and with their non-living environment. It involves the exchange of energy and matter among its components. The term "ecosystem" is derived from a Greek word meaning "study of home," emphasizing the concept of a self-sustaining environment where organisms and their surroundings function as a cohesive unit. As per V.S. Saravana Mani, an ecosystem is a community of various species engaging with one another and their environment, directly or indirectly, to sustain life processes.
