Question

Explain food chain.

Answer 1

Food Chain:

• In an ecosystem energy flows from one trophic level to another. A trophic level represents a group of organisms, which are either predators or preys. All organisms in an ecosystem are linked to one another based on their nutritional needs. The relation between the individuals in a linear chain is a food chain.
•  A food chain always begins with the producers. The various components of the food chain are a group of organisms. There is transfer of food energy through series of organisms by repeated eating and being eaten.
• A food chain shows how each organism gets food and how nutrients and energy are passed from one creature to the other. Food chains begin with plant-life, and end with animal-life. Some animals eat plants, some animals eat other animals.
