Terrestrial food chain shows a relationship between plants and animals found on desserts, grasslands, and forests.

The energy pyramid has a large base and becomes smaller at the top.

At the bottom or the first level are the producers. Here, the energy and the number of organisms are very high. For each level or feeding stage, the energy and number of organisms decrease so the pyramid becomes smaller at the top. And at the top are carnivores like a tiger, eagle, etc.
