(a) Draw a pyramid of numbers where a large number of insects are feeding on the leaves of a tree. What is the shape of this pyramid?
(b) Will the pyramid of energy be also of the same shape in this situation? Give a reason for your response.
The biomass of a standing crop of phytoplankton is 4 kg/m2, which supports a large standing crop of zooplankton having a biomass of 11 kg/m2. This is consumed by small fishes having a biomass of 25 kg/m2, which are then consumed by large fishes with a biomass of 37 kg/m2.
Draw an ecological pyramid indicating the biomass at each stage and also name the trophic levels. Mention whether it is an upright or inverted pyramid.
Give a scientific reason:
The pyramid of energy is always upright.
| In a forest ecosystem, a large population of insect feeds upon a banyan tree. Several small birds feed upon these insects. The small birds are fed upon by big-sized birds. |
- With respect to this ecosystem, draw a pyramid for each biomass and a pyramid of number.
-
If 20,000 Kcal energy is available at the level of insects, calculate the amount of energy available at the level of big-sized birds.
