Understanding the Food Chain/ Food Web

Food Chains/ Food Webs are what biologists describe as a relation between animals in their habitat and the foods they eat. A simple food chain would be the sun grows the grass, the deer eat the grass, and the wolves eat the deer. If something goes wrong with one animal then it will reflect on all the other animals. If we have a drought then no grass will grow, so the deer will starve and slowly start dying out. Then there is no food for the wolves and they start running down to dangerously low numbers. Then they are classified as endangered animals. Once an animal is endangered people start protecting them and laws are passed to protect the animals.  Pollution is a major cause of the endangerment of certain animals and a break in the food chain or food web. Pollution involves the inappropriate discharge of waste materials into the soil, water or atmosphere. One example is people using their cars too much and polluting the air.
