• Competition (density dependent)

• Herbivory Effect

• Weather (density independent)

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.

• Predator-Prey Relationships

• Weather (density independent)

• Herbivory Effect

• Competition (density dependent)

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?

• Predator-Prey Relationships between predators and herbivores (density dependent)

• Herbivory Effect

• Competition for sunlight (density dependent)

• Weather (density independent)

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?

• Predator-Prey Relationships (density dependent)

• Competition for Food (density dependent)

• Temperature (density independent)

• Weather (density independent)

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?

• Overcrowding (density dependent)

• Competition (density dependent)

• Weather (density independent)

• Food (density dependent)

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?

• Natural disaster (density independent)

• Overcrowding (density dependent)

• Predator-Prey Relationships (density dependent)

• Shelter (density dependent)
