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.
Any device connected to the IP network must have an unique IP address within the network. An IP address is analogous to a street address or telephone number in that it is used to uniquely identify an entity. The traditional IP Addresses (known as IPv4) uses a 32-bit number to represent an IP address, and it defines both network and host address.
