Question

9. The pyramid of number in a grassland
ecosystem is
(a) linear
(b) upright
(c) irregular
(d) invert​

Answer 1

in a grassland ecosystem, pyramid of number will be upright because number of primary consumers are less than primary producers and that of secondary consumers are less than primary consumers and so on. On the other hand, in a parasitic food chain the pyramid of number will be inverted

Answer 2

Answer:

option b) upright

Explanation:

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.
