We built our own ecosystems using gravel, 6 small plants, 2 empty soda bottles, sand, soil, clear plastic wrap, 2 rubber bands and water in a spray bottle. Thank you parents for providing our supplies. One ecosystem was then placed in the sun, and the other was placed in a dark cupboard.Expected results: If all goes according to plan, we should observe that plants need sunlight in their ecosystem to stay healthy. The plants in the dark area should be pale and unhealthy. Smaller plants may even be dead.Conclusions: Plants in the sun should be green and healthy. Plants in the dark should be pale and not healthy. Sunlight is neccessary for healthy planys. Most plants on Earth depend on light from the sun.
