Tundra Energy Pyramid
The energy pyramid shows the process of energy going to a different organism. It is similar to the food chain but it shows the energy from each organism. "If 100% of the energy is available at the first trophic level, what percentage of the total energy is available at the highest trophic level?" If plant material 15-30% and if animal material 60-90%. "Why is energy lost?" Energy is lost because it is usually used up by the animal whereas a plant cannot move.

Tundra Food Web
The relationship in the food web is like most. The plant uses photosynthesis for energy, the lemming and musk oxen eat the plants for energy, and the snowy owl and arctic fox eat the lemming and musk oxen for energy. The arctic fox also eats plants for energy which means it is an omnivore. A herbivore is an animal that eats only plants. For example the lemming and musk oxen. There is also the snowy owl who is a carnivore, an animal that eats only meat. The wolf and caribou is an example of predator prey relationship. The caribou hunts and the wolf eats the left over or the caribou. If the plants were gone, all the animals would die. For instance the lemmings would have no plants to eat therefore it would eventually die, leaving the snowy owl with no food. Examples of density dependent factors in the tundra would be food and water as population increases. examples of density independent factors would be food shortage and weather changes.
