Energy flows ecosysytems consists of producers and consumers of energy, Plants convert and produce energy directly from sun through photosynthesis, bacteria obtain energy from chemical available in the ecosystem. All other organisms are consumers of oxygen, water and food directly and indirectly from from energy producers.
Consumers produce wastes which support rpoducers.
This is the essential energy flow of the earth's ecosysytem. It is best illustrated by the simple food chain Homeostasis Refers to the idea of relatively constant conditions, i.e. being in balance where internal processes adjust for changes in external conditions. It is therefore not a static state but one of dynamic equilibrium dependent on integration and constant adjustment between different parts of the system. Some ecosystems have low inertia but high resilience or vice versa, but a healthy ecosystem is one with high inertia and resilience. Feedback loops maintain stability in ecosystems positive feedback, e.g. global warming leads to ice melt which increases surface absorption of heat, which will futher increase global warming.
