Options

  1. AOnly 1 and 5 are incorrect
  2. BOnly 4 is correct
  3. CAll are incorrect
  4. Donly 2 and 4 are correct

Correct answer

D. only 2 and 4 are correct

Step-by-step solution

Identification and enumeration of plant and animal species of an ecosystem gives its species composition. Vertical distribution of different species occupying different levels is called stratification. The components of ecosystem are seen to function as a unit when you consider productivity, decomposition, energy flow and nutrient cycling. The abiotic component is the water with all the dissolved inorganic and organic substances and the rich soil deposit at the bottom of the pond.
