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.
• 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 nonliving factors). Label them abiotic and
biotic items. Label this section
Ecosystem.
• COLOR ALL sections.
