Match the following

• What is a niche? What happens if 2 species of organisms occupy the same niche?

• Phosphorus

• Why is nitrogen-fixing bacteria so important to plants?

• A niche is an organism’s  way of life. A niche is the way an organism uses its physical and biological conditions in which it lives.  It includes habitat, resources and the organisms role in the environment; If 2 species live in the same niche, competition will occur.
