Food
Pyramid
The food pyramid shows how the levels of something can be greater than the other ones the very top shows 100% of energy they can eat everything the second would be 75% the third would be 50% and the fourth wich is the producer would be only 25% because they get their food through photosynthesis. Because the producers get their energy from the sun its very able that they have the lowest level of engergy and that is why most animals eat each other.
Top-100%
Second-75%
third-50%
fourth-25%
Second-75%
third-50%
fourth-25%
In the two graphs above the energy in them is shown by what herbivore(plant eater) eats which producer(grass and plants) and which omnivore(meat and plant eater) eats which carnivore(meat eater). The energy in each of these graphs goes to the animal that eats the other they are alike because when they eat they get energy but when another animals eats them their energy along with all the ones it had before builds up. If a mutation of disease entered on animal it would affect the whole food chain and web, because as each animal eats they are getting what all the other ones did. Since the Tundra is a very dependant place they are cold and dry so, they need help which makes them density-dependant. Not many animals can live in the Tundra and that affects how many more can adapt and be able to be succeptable to all of the conditions. If a pack of wolves take over the Tundra than all the animals would have no chance because wolves are at the top of the food chain so they are the "main man" of the Tundra and alll the other animals have no control over how they rule their teritory.
