Understanding Human Population Growth: Concepts and Patterns in Honors Biology

This assignment summarizes key concepts from Lesson 36 of Honors Biology focusing on human population dynamics. It addresses the rapid growth of the human population due to advancements in sanitation, health, and agriculture. The lesson covers definitions of population, dispersal patterns, and limiting factors in growth. It also explains the human population growth curve and distinguishes between exponential and logistic growth models. Understanding these concepts is critical for addressing population-related challenges today, especially in developing countries.

  1. Homework • Page 393 summarizing the concepts sections 1 – 3 Lesson 36 Honors Biology

  2. 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

  3. 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

  4. 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

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

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

  7. 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
