  1. Biodiversity Chapters 10-12 and some of 6

  2. Food Web Each trophic level that energy goes up, 90% of it is thrown away

  3. Evolution Evolution can be fast or slow or even ’instantaneous’ compared to time. Evolution allows species to adapt to each other in a never ending cycle of adaption. Evolution is the basis of ancestry of all the organisms we know.

  4. Habitat Destruction There are many types of habitat destruction which lead to loss of biodiversity, extinction, even nothing at all (like stepping on 1 pine cone and no one else goes near the forest). Examples are : fragmentation and alteration

  5. Regions Different regions effect biodiversity, like how less species live in an extremely cold tundra than a rain forest.

  6. Genetic Diversity This could be anything from the color of a banana, to the shape of a unicorns head. Leads to different species if left untreated and if they survive the diversity within their own species.

  7. Ecosystem Diversity Diversity in an ecosystem: The more species / organisms that are within an ecosystem makes more diversity. Diversity can help an ecosystem in aesthetics and within it self.

  8. Balance Predator and prey relationship: When the predators are high, prey is low. And vice versa. This creates bumps in the equilibrium of predator and prey relationship

  9. Threats Habitat destruction Introduced invasive species Genetic Pollution Overexploitation Climate Change

  10. Protection Biodiversity Banking Gene Banks Location Specific Approaches Reduction of Pesticides
