Aim: How does biodiversity increase the stability in an ecosystem? DN: What will there always be more of in an ecosystempredator or prey? Explain. What is meant by the “Circle of Life”? All living things are dependent on one another Why is this important? Why are there so many different species on earth? Due to the evolution of related organisms ADAPTING TO different environments Biodiversity The diverse number of species (variety of species) in a given area Look for the biodiversity of the soil Why is biodiversity important? What happens If insecticide Is sprayed? All living things are interdependent on one another How do living things depend on each other? All organisms are interrelated by the food web. If one organism in the food web decreases, then others will either increase or decrease What happens to an ecosystem when biodiversity decreases? Ecosystem stability decreases Stability – the ability of the different populations of organisms to survive an environmental change. How does great biodiversity maintain ecosystem stability? In an ecosystem with great biodiversity, organisms rely on more than one type of food, increasing their stability. If one species dies off, others may step in and take over its niche Which ecosystem has greater stability? The forest has greater stability because it has greater biodiversity How is biodiversity lost? Natural disaster & human activities Why is biodiversity important to us? It ensures the availability of a rich variety of genetic material. Biodiversity has provided us with medicines, natural insecticides, & other useful resources.
