AssignmentAssignment•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.

•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.
