A model of a biome can be created by including several of the abiotic (nonliving) and biotic (living) factors found in the actual ecosystem. A successful model replicates the conditions of an ecosystem, demonstrates some of the processes that take place in the ecosystem, and sustains itself. Aaliyah created a model of a biome by following these steps.

sand being poured into a glass bottle soil being added to a glass bottle plants and water being added to a glass bottle model biome with several plants and a cap on top
First she added rocks and sand to a bottle. Then, she carefully placed soil on top of the sand. She planted ferns and other small plants and added water to the soil. She placed a thermometer in the bottle and closed the bottle with its cap. She then placed her model in front of a window and monitored it for five days.

Identify the abiotic and biotic factors that Aaliyah included in her model.
