Q1.
Draw the feeding relationships for the remaining organisms by adding arrows, similar to those in Fig. 12.8.
Answer
Fig. 12.8 already shows Grass → Hare → Leopard. The organisms still to be linked are the grasshopper, the frog, the snake and the eagle. Add these arrows:
Grass → Grasshopper (the grasshopper is a herbivore, so it feeds on the producer) Grasshopper → Frog (the frog is a small carnivore that catches insects) Frog → Snake (the snake preys on frogs) Snake → Eagle (the eagle is a large carnivore at the top)
Put together with what is already there, the grassland now has two chains starting from the same producer:
Two food chains in the same grassland, both starting at the grass.
Why it happens: the grass appears in both chains because a producer supports several different herbivores at once. This is the first hint of a food web — real ecosystems are never a single line.
Q2.
Which is another food chain that can be drawn for the organisms given in this activity?
Answer
The one the book itself gives:
Grass → Grasshopper → Frog → Snake → Eagle
Reading it as trophic levels:
Trophic level
Organism
Role
First
Grass
Producer — makes food from sunlight
Second
Grasshopper
Herbivore
Third
Frog
Small carnivore
Fourth
Snake
Carnivore
Fifth
Eagle
Large carnivore
Tip: a chain always begins with a producer, because that is where the energy enters. Any chain you draw that begins with an animal is incomplete.
