Protecting an area can biodiversity. Deforestation, pollution, and over hunting can biodiversity. 2
5. Protecting biodiversity is important to keep the planet. The more an ecosystem is, the and more it is. 6. A keystone species is a species that influences the of many other species in an ecosystem. a. If the keystone species, the entire ecosystem may. b. example: earthworms are important for. The more earthworms, the the soil, the better the grass. Circle the soil sample below that should be the most fertile. 3
7. Gene Pool Diversity the number of diverse traits in a species a. The traits in a species, the better chance they have of. b. species that lack a gene pool are able to adapt to changes in their environment. 8. Not protecting biodiversity: a. The biggest threat to biodiversity is of. b. If we don t protect biodiversity species can become or. 9.

The Species Act Convention on International in Endangered Species c. habitat preservation The effective way to preserve biodiversity is to protect entire. NO DIVERSITY DIVERSITY 12. Biodiversity Demonstration a. How many different species do we have in Trail 1? If a disease went through this population, and killed all of the yellow squares, how does that affect the population? b. How many different species do we have in Trial 2? If a drought went through this population, and killed all of the red squares, how does that affect the population? c. What was different with the second demonstration? d. How did biodiversity help this population? e. Would the death of part of a population effect the food chain 5
13. Sustainability the capacity to. How biological systems remain and over time. 14. Sustainability examples: Two farmers try to out-produce each other by using different planting techniques. Field 1 grew more until a virus killed all of crop 2. How would this virus effect the two farmers? How are the farmer s fields similar to how biodiversity allows an ecosystem to be stable? 6
