The correct answer is Option (2) → Number of secondary consumers

The figure is a pyramid of numbers: each value counts individuals, not weight. From the base: A (5,842,000) primary producers, B (7,08,000) primary consumers, C (3,54,000) secondary consumers, D (3) tertiary consumers.

Option (1) Number of primary consumers — Incorrect. The primary consumers in the grassland pyramid number about 7,08,000. The value 3,54,000 belongs to the next level, the secondary consumers.

Option (2) Number of secondary consumers — Correct. In the pyramid of numbers of a grassland, the producers number about 58 lakh, primary consumers about 7 lakh and secondary consumers about 3,54,000, with only 3 tertiary consumers. The value counts individuals, so it is a number, not a dry weight.

Option (3) Dry weight of secondary consumers in kgm^-2 — Incorrect. The figure is a pyramid of numbers, so its values count individuals. It does not show dry weight in kg m⁻².

Option (4) Dry weight of primary consumers in kgm^-2 — Incorrect. The value is a number of individuals, not a dry weight, and it belongs to the secondary consumers, not the primary ones.
