Population Ecology Review

Largest number of individuals of a population that the environment can support  

• carrying capacity
• primary succession 
• denitrification
• mutualism

An environmental factor such as storms and extreme heat or cold that affects population regardless of their density

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

Any factor that limits population growth

• Limiting Factor
• Immigration
• Succession
• Abiotic Factor

How do predator-prey relationship affect a population?

• They are in competition with each other
• One will go extinct
• Predators have exponential growth
• Controls size of both populations

When a population has reached carrying capacity

• Growth & Immigration are equal to Death & emigration
• Growth & Immigration are less than Death & emigration
• Growth & Immigration are greater than Death & emigration
• Growth is exponential

__________ growth shows growth of a population under environmental constraints (carrying capacity-K) that sets a maximum population size 

• logistic
• exponential
• niche
• uniform

What two factors influence population growth?

• increase Emigration & Immigration
• increase Immigration rate & increase Birth rate
• increase Birth rate & increase Death rate
• Death rate & Emigration rate

What two factors are attributed to population decline?

• increase Birth rate & increase Death rate
• increase Death rate & increase Emigration rate
• Emigration & Immigration
• Immigration &  increase Birth rate

Population numbers get too large for the environment to support it and growth slows reaching carrying capacity, this growth is known as _______.

• Exponential growth
• Logistic growth
• Natality
• Emigration

One reason predators might increase is if...

• The weather is warmer
• Parasites have increased
• The prey have increased
• Food has decreased
