Question

Write the Characteristics of food chain?​

Answer 1

Characteristics of a food chain

1. Linear Structure - In an ecosystem, a food chain represents the transfer of nutrients and energy from one organism to another.

2. Energy Flow - Energy moves from the producer to the primary consumer, then to higher-level consumers, in a single path in a food chain.

3. Trophic Levels - Depending on where they are in the food chain, different types of organisms are categorized into different trophic levels.

4. Energy Transfer Efficiency - The amount of energy available at each trophic level decreases as it climbs up the food chain.

5. Dependence on Producers - In the end, all species in a food chain rely on producers (often plants) to use photosynthesis to turn sunlight into useful energy.

Answer 2

Food Chain

The sequence of living organism in an ecosystem in Which one organism consumes another organism to transfer food energy is called food chain.

Characteristics of food chain

• It shows nutritive interaction between living organisms,
• It is always straight
• There is a unidirectional flow of energy. (sun→ producers → consumers)
• There are usually 3-4 trophic levels in a food chain.
• Organisms can occupy different positions in different food chains.
• As per second law of thermodynamics. 80-90% of energy is lost as heat at each trophic level
