Detailed explanation-1: -Introduction. Closed Ecological Systems (CES) are associations of species of organisms that are exchanging materials with each other, thereby forming material cycles, but which are always open to energy exchange from outside.
Detailed explanation-2: -Any ecosystem is an example of an open system. Energy can enter the system in the form of sunlight, for example, and leave in the form of heat.
Detailed explanation-3: -A closed ecological system for an entire planet is called an ecosphere.
Detailed explanation-4: -There are two types of ecosystems, closed and open. Closed ecosystems are ones that do not have any inputs (exchanges of energy from the surrounding environment) or outputs (exchanges of energy from within the ecosystem). Open ecosystems are ones that have both inputs and outputs.
