A duck population normally begin migrating south right after the last rain of the late summer season. Suddenly, they’re migrating much earlier. The climate has been changing far too often which is altering the effects of their magnetite.

One of the wolf populations begins to compete with a new bear population for the same herbivores. Over time, bushes, trees and rivers improve in numbers. There is an effect on the producer populations. What is the limiting factor to the herbivore?

A honey-badger digs the ground tunnels in search for snakes. In one occasion, the badger finds a snake and competes with it. The badger leaves scratches and bite marks on the snake before it escapes. After twenty-four hours the snake dies. What is the limiting factor to the snake?

The wolf population gets reintroduced to the ecosystem. There are enough deer to go around, so they eat comfortably. The wolf population begins to grow out of control with so much food. The different wolf families then begin to compete for the few caves that exist. Not everyone has good shelter so some have to sleep in the forest floors. What is the limiting factor to the wolves?

The wolf goes extinct, and the deer population has no predator to worry about. They graze the land. Because there is no more food. Some of the deer begin to bite at each other, while others die of starvation. What is the limiting factor to the deep population?

Which of these factors affects large and small populations in the same ways? (It does not matter what size the population is)

Which of these limiting factors has an influence on the growth of a population based on its density?

In the graph to the right, what is the population of deer at the carrying capacity of the environment?

When a population grows past the ecosystem's carrying capacity, what happens to the population?

The graph to the right shows the interaction of the wolf and moose populations on Isle Pekie. If the moose population continues to increase, the wolves' food supply will increase. What will most likely happen to the wolf population as a result?

Due to stress, large numbers of female lemmings miscarry their young and fail to reproduce.

Many fish die due to a drastic change in water temperature.
