Activity 12.7 Let us draw (Pages 199-200) Class 8

Fig. (a) represents a crop field with millets, mice, and an eagle.

Count the number of each type of organism in Fig. (a).

Make a table and set a number in the table against each of the organisms.

Arrange the numbers in ascending order, consider the highest number at the base, and the lowest at the top.

Place the mouse, millet, and eagle appropriately in Fig. (b).

What figure do you get? It looks like a pyramid. Complete the pyramid in Fig. (b).

Answer:

Each organism in a food chain has a specific position, called a trophic level.

Producers (like green plants) are at the first trophic level.

Herbivores (like hares and deer) are at the second level.

Small carnivores (like frogs) are at the third level.

Large carnivores (like tigers or vultures) occupy the next level.
