Primary forests are usually rich in biodiversity. Biodiversity is the variety of life and life processes. When a natural ecosystem is diverse, it has a variety of living organisms. In this inquiry, scientists wanted to know how much biodiversity the world’s forests contained. Additionally, scientists studied the impact of invasive species and some types of fire on forests’ biodiversity. Be sure to check out the lesson plans for both this Inquiry and the entire journal in the Educators tab below.
