Question

What is a food chain? Explain it with an example.

Hint:

Food chains maintain the balance of ecosystems by transferring energy at different levels.

Answer 1

Definition of Food Chain:
A food chain represents the transfer of energy from one organism to another in an ecosystem. It shows how organisms are linked by their feeding relationships.
Example of a Food Chain:
\begin{center} \[ \text{Grass} \rightarrow \text{Grasshopper} \rightarrow \text{Frog} \rightarrow \text{Snake} \rightarrow \text{Eagle} \] \end{center} Explanation:
1. Producers (Grass): Plants prepare food through photosynthesis.
2. Primary Consumer (Grasshopper): Herbivores that feed on plants.
3. Secondary Consumer (Frog): Carnivores that eat herbivores.
4. Tertiary Consumer (Snake): Feeds on smaller carnivores.
5. Apex Predator (Eagle): The topmost predator in the food chain.
