TEK 7B calculate birth rate and exponential growth

Beginning Population 100, Birth Rate 20, Death Rate 40

the final population size will...

• increase

• decrease

• stay the same

• This question is dumb... There is no relationship between Math and Science

Birth Rate 20, Death Rate 50
How will the population change

• Increase
• Decrease
• Stay the same

What does it mean if N equals a negative number when calculating a change in population size?

• It means you did the calculation wrong

• It means the population is decreasing

• It means the population is increasing

• It means the population is in equilibrium

Exponential population growth can be described as

• growth when resources are limited

• a j-shaped curve

• a s-shaped curve

• growth that reaches carrying capacity

Logistic population growth can be described as

• growth when resources are limited

• a s-shaped curve

• reaching carrying capacity

• all of the above

occurs when population slows or stops following a period of exponential growth.

• no growth

• population growth

• logistic growth

• exponential growth

Exponential Growth occurs when-

• populations have plenty of food/space

• home to keystone species

• have few evasive species in a habitat

• have little to no competition or predators

Worldwide there were 20 births and 8 deaths per 1000 people in 2017. Calculate the growth rate of the world.

• 1.1%
