Detailed explanation-1: -Ecosystem: The collection of all living organisms in a geographic area, together with all the living and non-living things with which they interact.

Detailed explanation-2: -Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity. Every factor in an ecosystem depends on every other factor, either directly or indirectly.

Detailed explanation-3: -A habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. For an animal, that means everything it needs to find and gather food, select a mate, and successfully reproduce.

Detailed explanation-4: -An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents.

Detailed explanation-5: -Ecology is the study of organisms and how they interact with the environment around them. An ecologist studies the relationship between living things and their habitats.
