What is the difference between a foodchain and a foodweb?

Answer 1

A food chain starts of with Producers, such as plants and algae. Producers are at the start, or bottom of the food chain because they do not eat other biotic factors to get the energy they need to survive. Instead of taking energy from food , producers get energy by converting it from carbon dioxide and water using sunlight. This process is called photosynthesis. Other biotic factors in the food chain survive by eating the producers. This gives them the energy that producers obtained through photosynthesis. These biotic factors are called consumers because they eat other organisms to get their energy, rather than direct from the sunlight. These consumers can be called carnivores such as a wolf, which eat meat only but consumers may be called omnivores when they eat both meat and plants, such as a bird. So basically a food chain is were energy is past on through different organisms. A food web is were two or more food chains are interconnected with each other.
