24. 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.

25. 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.
