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.
A food chain shows how each living thing gets its food. Some animals eat plants \â æ æçææ¤çæ¼çæçå°©, and some animals eat other anim\àµ¡ls \â ææçæ¸æ¤çæ¼çæçå°© others eat both \â ä¼æ´æ¸æ¤çæ¼çæçå°©. For example, a simple food chain links the phytoplankton, zooplankton, small fiså°h, and then big fish. Food chains are linear.
