Food Web Vs. Food Chain

Before learning about the food chain, you need to understand what the difference is between a food chain and a food web. A food chain consists of six items: the energy source, the producer, the primary consumer, the secondary consumer, the scavenger, and the decomposer. Each of these items play a role in the food chain and are needed for the balance of life. Even though helpless animals may be sacrificed, everything plays its role in the food chain. A food web consists of many interlocked food chains in an area called a biome. A biome is an area of the world that has different characteristics such as temperature, humidity, and rainfall from other biomes. A food web has only one energy source, but many producers, consumers, scavengers, and decomposers are involved.
