Choose the correct answer from the codes given below.
Assertion (A) : The pyramid of grassland ecosystem is upright.
Reason (R) : The producers are maximum in number and tertiary consumers are least in number.
Answer: A
Both statements are correct, so the answer is (A) and (R) are correct.
An ecological pyramid of numbers for a grassland is upright: the base is formed by a very large number of grasses and herbs (producers), above them fewer herbivores such as grasshoppers, then still fewer carnivores such as frogs and snakes, and at the top only a few tertiary consumers such as hawks. The Reason states exactly this pattern of numbers, which is why the pyramid narrows upward.
The options saying only one statement is correct are therefore wrong, and the last option is wrong because the Reason does describe why the pyramid is upright.
