Ch. 1 ReviewPopulations & Communities
Lesson 1 Big Ideas
• An organism gets the things it needs to live, grow, and reproduce from it’s environment.
• Biotic and abiotic factors make up a habitat.• The levels of organization within an ecosystem
are organism, population, and community. • Click the link to watch the Ecosystems Song:

Lesson 2 Big Ideas
• Populations can change in size when new members join the population or when members leave the population.
• Some limiting factors for populations are weather conditions, space, food, and water.
What is the population density of “mini” T-Rex’s on the 3 ft by 4 ft piece
of land below?
Remember…
• Population Density= Number of Individuals Unit Area
What is the population density of “mini” T-Rex’s on the 3 ft by 4 ft piece
of land below? 1 mini T-Rex per ft2
What are two ways to leave a population?

1. Emigration2. Death
What are two ways to join a population?
What are two ways to join a population? 1. Immigration2. Birth
What are factors that limit population growth?
What are factors that limit population growth?
Water, food, living space, and weather conditions
Lesson 3 Big Ideas
• Every organism has a variety of adaptations that are suited to its specific living conditions to help it survive.

• Two major types of interactions among organisms are competition and predation.
• The three main types of symbiotic relationships are mutualism, commensalism, and parasitism.
