Then environment is in dynamic equilibrium when it is gaining?

The environment is in dynamic equilibrium when it is gaining and losing materials or energy at equal rates, resulting in a stable condition over time. This balance allows ecosystems to maintain their functions and support diverse forms of life. For example, in a forest ecosystem, the processes of photosynthesis and respiration continuously cycle carbon and oxygen, keeping the system in equilibrium. Disruptions to this balance can lead to environmental changes and potential degradation.
