Solution:

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows.

Ecosystems are communities of organisms and non-living matter that interact together. Each part of the ecosystem is important because ecosystems are interdependent. Damaged or imbalanced ecosystems can cause many problems.

Ecosystem functions are conceived as a subset of ecological processes and ecosystem structures. Natural processes, in turn, are the result of complex interactions between biotic (living organisms) and abiotic (chemical and physical) components of ecosystems through the universal driving forces of matter and energy.
