Unit 3 Exam Review Lectures 5 & 6

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

• Density Independent limiting factors start to occur resulting in the population going farther above carrying capacity.
• Density Dependent limiting factors start to occur resulting in the population going back below carrying capacity.
• The population will go extinct due to lack of resources
• The population grows then finds a new carrying capacity

Limiting factors which impact the size of a population no matter how large that population is.

• Density Independent Limiting Factors
• Density Dependent Limiting Factors
• Carrying Capacity
• Exponential Growth

An environmental factor such as storms and extreme heat or cold that decrease a population are considered to be. 

• density- dependent factor
• population density
• dispersion
• density- independent factor

A lion and a cheetah attempt to occupy the same niche. The more aggressive lion survives; the cheetah does not.

• Density-Dependent: Competition

• Density-Independent: Competition

• Density-Dependent: Predator-Prey

• Density-Independent: Predator-Prey

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

• Herbivory Effect

• Competition
