Power+Point+Information

Use this page to collect and organize the information and pictures needed by your group to create your power point.

-Discuss the major limiting factors of the ecosystem and discuss examples of density dependent and density independent factors. -Answer the question, “How has your biome been destroyed, or how can it be destroyed?” Describe its recovery process and tie it to succession. -Describe the major threats to that ecosystem. -Describe endangered species found in the ecosystem and species that have gone extinct in your ecosystem. -Describe positive and negative human effects to the ecosystem. -Describe how climate change is affecting the ecosystem. -Answer the essential question that is key to your biome.
