Identify the trophic level for insects and leopards. Construct a food chain where a vulture is a quaternary consumer. Name an organism group vital to ecosystems but not depicted.

c) Name the trophic level occupied by the following organisms:

c) (i) Insects
Insects feed on Green Plants (producers) and Decaying Leaves. When feeding on producers, they are primary consumers.

• Primary consumers

c) (ii) Leopards
Leopards feed on Rabbits and Snakes. Rabbits are primary consumers. Snakes are secondary consumers (feeding on rats, which are primary consumers). Therefore, leopards can be secondary or tertiary consumers.

• Tertiary consumers (as they can feed on snakes, which are secondary consumers)

d) Construct a food chain in which the vulture is a quaternary consumer
A quaternary consumer is at the fifth trophic level.

• Green Plants $\rightarrow$ Rats $\rightarrow$ Snakes $\rightarrow$ Leopards $\rightarrow$ Vultures

e) (i) Name one group of organism not shown in the food web but play an important role in the ecosystem

• Decomposers (e.g., bacteria, fungi)
