• B. Always inverted
• C. Either erect or inverted
• D. Irregular

Answer 1

The correct option is A Always erect

An ecological pyramid is a graphical representation of each trophic level in a given ecosystem. The pyramid of numbers is a graphical representation the number of organisms in a food chain in a particular ecosystem. In a grassland ecosystem, the producers which are grasses are the maximum and are followed by the primary consumers-herbivores. The secondary consumers-snakes, lizards lesser in number and the final consumers the hawks and other birds are least in number. Therefore the grassland pyramid is always upright and erect.

So, the correct answer is option A.
