Definition of Food Chain

Definition of Food Chain

• A food chain is a series of organisms each dependent on the next as a source of food.

Components of a Food Chain

• Producers: organisms that produce their own food through photosynthesis, also known as autotrophs.
• Consumers: organisms that obtain energy by consuming other organisms.

Key Entities in a Food Chain

• Producers: first link in the food chain, convert sunlight into energy through photosynthesis.
• Primary Consumers: herbivores that feed on producers.
• Secondary Consumers: carnivores that feed on primary consumers.
• Decomposers: organisms that break down dead organisms, returning nutrients to the environment.
