Explain the core principles and stability of the ecosystem Good Day... Ecosystem is the interaction of biotic component and abiotic component . Biotoc component are the living things composes the ecosystem. Abiotic factor are environmental variables that would affect the biotic factor such as, water, oxygen, nutrients, minerals etc. and it also include the physical aspect of the environment like temperature, moisture, humidity, wind etc. In biotic component, different ecological relationship presented in order for an organism to survive. Each organism has a role necessary for the stability of ecosystem. If one organism is gone or extinct, other organism are also affected. The higher the diversity of organism in an ecosystem, the more it is stable. Biotic component needs abiotic component like nutrients and minerals which are needed for survival. If one abiotic component is missing, ecosystem will not exist. Hope it helps...=)
