Your answer: —  Â·  Correct: C

Explanation

Carrying capacity refers to the maximum population size or level of activity that an environment can sustain indefinitely without being degraded. For an environment to maintain its carrying capacity, two conditions are essential:

  • Resource Extraction: The rate of resource extraction must be less than or equal to the rate of resource regeneration. If extraction exceeds regeneration, the resource base is depleted. Therefore, Statement 1 is incorrect as it suggests extraction should be 'above' regeneration.
  • Waste Absorption: The generation of waste should remain within the absorption (assimilative) capacity of the environment. When waste exceeds this capacity, environmental pollution and degradation occur. Thus, Statement 2 is correct.

When these conditions are violated, the environment fails to perform its life-sustaining functions, leading to an environmental crisis.
