Question

Physical structure, that is characteristic for each type of ecosystem, is formed due to the :

• A. Interaction of biotic and abiotic components
• B. Vertical distribution of different species
  
• C. Stratification
• D. Both B and C

Answer 1

The correct option is A Interaction of biotic and abiotic components

The structure of the ecosystem includes the organisms and physical features of the environment, including the amount and distribution of nutrients in a particular habitat. It also provides information regarding the climatic conditions of that area.

The characteristic of each type of ecosystem is the interaction between biotic and abiotic factors. The components are linked together with various nutrient cycles and energy flows. Thus it can be visualized as a functional unit of nature.

Therefore, interaction of biotic and abiotic components results in physical structure that is a characteristic for each type of ecosystem.
