Double-Column Notes Format

• We will set up compbooks together.• 1st Fold your paper in half and draw a line

down the middle• 2nd Questions will go on the left-hand side• 3rd Answers will go on the right-hand side• 4th ALWAYS skip lines between questions

(everything should line up perfectly)

Question 1

• What is an organism?

• An organism is any living thing.

Question 2

• What must an organism obtain in order to live, grow, and reproduce?

• Food, water, shelter, and space

Space

Water

Shelter

Food

Question 3

• What is a habitat?

• An environment that provides the things the organism needs to live, grow, and reproduce.

Question 4

• Give an example of an area that contains many habitats.

• A forest: mushrooms grow in the damp soil, salamanders live on the forest floor, and woodpeckers build nest in tree trunks.

Question 5

• Why do different organisms live in different habitats?

• Because organisms have different requirements for survival.

Tropical HabitatArctic HabitatDesert Habitat

Question 6

• What are biotic factors?

• The living parts of a habitat.

Frog

Plant Life

Question 7

• What are the biotic factors of a prairie dog habitat?

• Grass and plants that provide seeds and berries; the hawks, ferrets, and eagles that hunt the prairie dogs; worms, fungi, and bacteria that live in soil.

Question 8

• What are two biotic factors from your environment?

• Answers will Vary!

Question 9

• What are abiotic factors?

• Nonliving parts of an organisms habitat

Sunlight

Soil

Oxygen

Temperature

Wa t e r

Question 10

• List and explain the five abiotic factors discussed on pg. 8 in the textbook.

• (the answers will be on the next slide. Make sure they go on the right-hand side of your compbook. #10 will have a long answer.)

Abiotic Factors (#10)

• Water: all living things require water to carry out their life processes.

• Sunlight: sunlight is required in order for photosynthesis to occur.

• Oxygen: oxygen is so important to the functioning of the human body that you can only live a few minutes with out it

• Temperature: the temperatures that are typical of an area determine the types of organisms that can live there.

• Soil: the type of soil in different areas influences the kinds of plants that can grow there. Soil is also used as a home for many organisms.

Question 11

• What are the four levels of organization?

• 1. Organism• 2. Population• 3. Community• 4. Ecosystem

Question 12

• What is a species?

• A group of similar organisms that are physically similar and can mate and reproduce.

The Frilled Shark is a very rarespecies of shark.

Question 13

• What is a population? Give an example.

• All members of one species in a particular area are called populations. The 400 million prairie dogs in Texas town would be an example of a population.

Question 14

• What is a community?

• All different populations that live together in an area.

Question 15• To be considered a community, different populations must live close

enough to interact. How do populations interact?

• Populations interact by using the same resources, such as food, water, and shelter.

Question 16

• What is an ecosystem?

• The community of organisms that live in a particular area, along with their nonliving surroundings.

Question 17

• Copy this statement in your compbook on the question side!

• The smallest level of organization is a single organism, which belongs to a population that includes other members of its species. The population belongs to a community of different species. The community and abiotic factors together form an ecosystem.

Question 18

• What is the study of how living things interact with each other?

• The study of ecology!!!!!
