How do you make an ecosystem in a jar?

Answer 1

Materials: soil, large clean jar, sand, rocks, green plants, twigs and sticks, crawling insects (ants, beetles, caterpillars) earthworms, screen, masking tape Procedures: # Place the soil in the bottom of the jar. # Add the sand and rocks. # Position the green plants so they will be easy for the insects to climb on and under. # Add an arrangement of the twigs and sticks. # Add the crawling insects and earthworms one at a time. # Place the screen (or lid with holes) on top of the jar. # Tape around the screen so it stays in place. Watch the insects and plants adapt to the environment.
