Lesson 36 Honors Biology

Character Education

• The human population is growing very fast, we will need to keep up and help others, more now than ever before

Lesson 36 Honors Biology

Objectives

• Define a population• Describe population dispersal patterns• List some limiting factors in population growth• Draw out a human population growth curve• Define the 4 regions of typical population

growth curves in nature

Lesson 36 Honors Biology

Class Notes

• The human population has grown because of better sanitation, improved health, and agricultural ability to produce food

• When birth rate (BR) and death rate (DR) are equal the population is stable, horizontal line

• When BR > DR the population grows, the line goes up• When DR > BR the population shrinks, the line goes

down• Human population growth is most rapid in developing

countries, slowest in developed countries

Lesson 36 Honors Biology

Notes

• Exponential Growth Curve – rate of growth stays the same and as a result the population increases

Notes

• Logistic Model – exponential growth is limited by a density dependent factor

Class Notes - 37

• Population distributions include:– Random : not evenly spaced– Uniform : evenly spaced– Clumped : clustered in space

• Currently the world population is over 6 billion• In 1776 the world population was 1 billion
