Question

Arrange the following living organisms in food chain in CORRECT order.

• A. Grass → Frog → Snake → Grasshopper → Eagle
• B. Grass → Frog → Grasshopper → Snake → Eagle
• C. Grass → Grasshopper → Frog → Snake → Eagle
• D. Grass → Grasshopper → Frog → Eagle → Snake

Hint:

In a food chain, the flow of energy starts from producers (like grass) and moves up to herbivores, carnivores, and apex predators. Always remember that the primary producers form the base of the food chain.

Answer 1

The Correct Option is C

Step 1: Understanding a food chain.
A food chain is a linear sequence of organisms where each organism serves as a source of food for the next one in the chain. The energy is transferred from one organism to another as it moves through the food chain. In this question, we are asked to arrange organisms in the correct order based on their roles in the food chain.

Step 2: Identify the organisms and their roles.
Let's break down the organisms listed in the question:
- Grass: Grass is a primary producer, meaning it forms the base of the food chain. It produces energy through photosynthesis and provides food for herbivores.
- Grasshopper: A herbivore, the grasshopper feeds on grass and is considered a primary consumer.
- Frog: The frog is a secondary consumer because it feeds on grasshoppers, making it a carnivore in the food chain.
- Snake: The snake is a tertiary consumer as it feeds on frogs, making it a higher-level predator in the food chain.
- Eagle: The eagle is an apex predator, meaning it is at the top of the food chain. It feeds on snakes, and because it has no natural predators, it is the final link in this chain.

Step 3: Arranging the organisms.
To create a correct food chain, we start with the producers at the bottom and move up through the consumers. The correct order of organisms, starting from the base of the food chain and moving to the apex, is:
1. Grass (Producer)
2. Grasshopper (Primary consumer)
3. Frog (Secondary consumer)
4. Snake (Tertiary consumer)
5. Eagle (Apex predator) Thus, the correct order is: Grass → Grasshopper → Frog → Snake → Eagle. Final Answer: Grass → Grasshopper → Frog → Snake → Eagle.
