Question 13 131 (i) Consider the amount of organic matter at the different trophic levels in an ecosystem given below: Trophic L
evel Amount of organic matter (in kg) 250 Tertiary consumers 150 Primary consumers 100 200 Primary producers Secondary Consumers On the basis of the data provided above, construct an ecological pyramid. Comment upon its nature giving at least one example of the type of organism occupying each of the above mentioned trophic levels.
1 answer:
primary producers: Phytoplankton
Primary consumers: Zooplankton
secondary consumers: Small fishes
Tertiary consumers: Large fishes
<h3 /><h3>Ecological Pyramid</h3>An ecological Pyramid is a graphical representation of the feeding relationship that exists between group of organisms in an ecosystem.
Inverted pyramids occurs in the aquatic ecosystem where
the biomass or organic matter of the fishes exceeds that is the primary producers.
The primary producer are the phytoplankton with the lowest organic matter if 100kg weight.
The primary consumers are the zooplankton with organic matter of 150kg in weight.
The secondary consumers are the small fishes with the organic matter that weighs 200kg.
The tertiary consumers are the large fishes with the organic matter that weighs 250kg.
The mass of organic matter represents the mass of living things in a particular trophic level. This is illustrated further in the attached diagram.
