Consider two plots, where plot 'X' is having less species compared to plot 'Z'. Select the true statement regarding X and Z.

Options

  1. APlot 'X' shows less year to year variation in total biomass
  2. BPlot 'Z' is less resistant to natural disturbance
  3. CPlot 'X' has more productivity than plot 'X'
  4. DPlot 'Z' has more productivity than plot 'X'

Correct answer

D. Plot 'Z' has more productivity than plot 'X'

Step-by-step solution

Biodiversity is can be said to be the measure of the complexity of interactions between organisms and the ecosystem. The greater the number of species results in more interactions which supports biodiversity. Also, helps an ecosystem or habitat to survive and adapt to environmental stress. These will increase the biomass of the particular ecosystem thus, making productivity high. Hence, the plot Z will have more productivity than plot X.
