Answer» Correct Answer - Option 3 : 2 and 3 only

The correct answer is 2 and 3 only​.

  • Abiotic components of an ecosystem include all chemical and physical elements i.e. non-living components.
  • Abiotic components can vary from region to region, from one ecosystem to another. They mainly take up the role of life supporters. They determine and restrict the population growth, number, and diversity of biotic factors in an ecosystem. Hence they are called limiting factors.
  • A terrestrial ecosystem consists of abiotic factors like climate, type of soil or rock, altitude, temperature, nutrients, and minerals, whereas abiotic components in an aquatic ecosystem include dissolved gases, depth of water, salinity, pH of water, light intensity, etc.
  • Biotic components can be classified into three categories:
    • Producers: These include all the autotrophs. They use light energy and synthesize food on their own, e.g. plants, green algae, etc.
    • Consumers: These include all the heterotrophs that directly or indirectly depend on producers for their food. Consumers are further categorized as herbivores, carnivores, omnivores, and parasites.
    • Decomposers: These include saprophytes that act on dead matter and decay them for their nutrition.
