उत्तर
Quantities of organisms are given-Hawks-50, plants-1000, rabbit and mouse-250 +250, pythons and lizard – 100 + 50 respectively
T4 (50) T3 (100) T2 (550) T1 (1000)
The pyramid produced is an upright pyramid of numbers where there is a gradual decrease in the number of organisms at each trophic level from T1 to T4. This is an example of a grassland ecosystem.
