Page 148- divide top 2/3 of page into half vertically. Label one column “Living things” and the other “Nonliving things”

8. What are Biotic Factors? Living or once living parts of an ecosystem.
Plants, animals, insects, bacteria, etc.

9. What are Abiotic Factors? Nonliving parts of an ecosystem
Water, sunlight, air, rocks, temperature, etc.

10. What is an Organism? An individual, living thing.
Use energy, grow, reproduce, respond to environment

11. What is a
Species?
A group or “type” of organisms that are physically similar and can reproduce.
Ex.) humans

12. Think and Discuss:

15. What is a

26. Assignment
Fold your paper into 6 equal rectangles. Turn your paper sideways.
Draw a plant or animal in one section. Label it by name and put “organism” under it.
Draw a population of the same organism ( 2 or more) in the next section. Label it population.

27. Draw a community from the same environment that the organism is found(2 or more species). Just use one section. Label it community.
Use the remaining 3 sections to draw an ecosystem from the same environment that the original organism is found
( include at least 5 living factors, 5 non-living factors). Label them abiotic and biotic items. Label this section Ecosystem.
COLOR ALL sections.
