A series of organisms each dependent on the next for food is known as food chain. It starts with a primary source like Sun and continues with consumers.
Example-Sun ( producer) - grass - grasshopper ( primary consumer) - Rat ( secondary consumer) - Snake ( tertiary consumer) - Hawk .
Firstly grass grows with help of Sunlight then grasshopper eats grass to survive then rat feeds on grasshopper and after that snake consumes rat and then hawk feeds on snake in their surroundings. This chain continues. Sometimes this foodchain also gets imbalanced.
