When referring to a megabyte for disk storage, the hard drive manufacturers use the standard that a megabyte is 1,000,000 bytes. This means that when you buy a 250 Gigabyte Hard drive you will get a total of 250,000,000,000 bytes of available storage.
A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal.
The Food Chain. A cheetah chases down and devours a zebra. The scene is not uncommon in Etosha, where the cycle of life, death, and birth has played out longer than any human can remember. In this situation, the cheetah is the predator, the animal that is eating, while the zebra is the prey, the animal being eaten. Predators and prey comprise only a portion of what is commonly known as a food chain. A food chain explains how food energy is transferred between living things in an environment. Every living thing in a food chain is either a producer or a consumer.
