The number of steps an organism is from the start of the chain is a measure of its trophic level. Food chains start at trophic level 1 with primary producers such as plants, move to herbivores at level 2, predators at level 3 and typically finish with carnivores or apex predators at level 4 or 5.The path along the chain can form either a one-way flow or a food web.he trophic level of an organism is the position it occupies in a food chain.
When you're at home, an IP address is assigned to your computer by your Internet service provider (think Time Warner Cable, Cox Communications, or AT&T). Since they are the ones giving you access to the Internet, it's their role to assign an IP address to your computer.
IP address is short for Internet Protocol (IP) address. An IP address is an identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol route messages based on the IP address of the destination. Contrast with IP, which specifies the format of packets, also called datagrams, and the addressing scheme.
