• Increases
• Decreases
• Fluctuates

What type of growth is represented behind?

• exponential

• Competition
• Predation
• Emigration
• Immigration

What does a limiting factor do?

• makes a population grow large
• stops a population from growing large
• helps organisms adapt to abiotic factors
• provides geographical boundaries for migration

An environmental factor such as predation, disease, and competition that depends on the number of members in a population per unit

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

NGSS.MS-LS2-4

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

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

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
