Solution
The correct option is A C
The pyramid of numbers describes the relationship in terms of the number of producers, herbivores and the carnivores at their successive trophic levels. The number pyramid varies from ecosystem to ecosystem. Partly upright pyramid of number is seen in the forest ecosystem where the number of producers are lesser in number and support a greater number of herbivores and which in turn support a fewer number of carnivores thus making the pyramid again upright. Thus, the correct answer is option D.
