Which of the following is correctly matched ?

  1. Stratification-Population
  2. Parthenium hysterophorus-Threat to biodiversity
  3. Aerenchyma- Opuntia
  4. Age pyramid-Biome

Answer

(2) Parthenium hysterophorus-Threat to biodiversity

Solution

Parthenium hysterophorus (carrot grass) is an alien invasive weed; as per NCERT, alien species invasions such as carrot grass ( Parthenium), Lantana and water hyacinth ( Eichhornia) are a major cause of loss of biodiversity. ⇒ (2) is correctly matched.

∵ Stratification (vertical distribution of species at different levels) is a feature of an ecosystem/community, not of a population.

∵ Aerenchyma is found in hydrophytes (e.g. Hydrilla, water hyacinth), whereas Opuntia is a xerophyte with phylloclades.

∵ An age pyramid represents the age structure of a population, not a biome.

Answer: (2)
