  • They all live together as interdependent components. 
  • The interactions of a particular group of organisms with abiotic factors within a particular habitat resulting in clearly defined energy flows and material cycles on land, water, and air, are called ecological systems.

Explanation:

Abiotic factors:

  • They refer to all the non-living components like physical conditions (temperature, pH, humidity, salinity, sunlight, etc.) and chemical agents (different gases and mineral nutrients present in the air, water, soil, etc.) in an ecosystem.

  • Temperature,
