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.
At its core, an IP address is an online unique identifier. Every computer has its own IP address, and it is through this naming system that computers can connect with each other and share data. A standard IP address (using what's known as the IPv4 protocol) contains four individual numbers separated by a decimal. While every computer is given its own IP address, the outside world rarely has access to it.
