The three main cycles of an ecosystem are the water cycle, the carbon cycle and the nitrogen cycle. These three cycles working in balance are responsible for carrying away waste materials and replenishing the ecosystem with the nutrients necessary to sustain life.

Examples of natural processes:

• energy flow and nutrient cycles ( photosynthesis , food webs, decomposition webs)
• sediment transport and soil formation.
• the water cycle.
• reproduction/ regeneration mechanisms.
• natural disturbances (fires, floods, storms)
• succession.

Natural cycles balance and regulate Earth and its atmosphere.

The seasons are a well-known example of a cycle. You may have studied the water cycle or the rock cycle in school. These are just two examples of cycles. Very simply, when scientists talk about cycles, they are talking about sequences of events that repeat themselves.
