Write the characteristics of food chain.

The main characteristics of a food chain are that it shows the flow of energy from one organism to another in a sequence. A food chain starts with producers (plants), which are eaten by herbivores, and then carnivores. Energy is transferred step by step but decreases at each level. Food chains help maintain ecological balance.

Characteristics

• Starts with producers like plants
• Shows energy flow in a straight line
• Each level is called a trophic level
• Energy decreases as we move up
• Maintains balance in the ecosystem

Example of Food Chain

Grass → Grasshopper → Frog → Snake → Eagle
