9. What is coral bleaching
What is coral bleaching? - coral bleaching happens when the coral expels the alga that helps it photosynthesis and turn sunlight into sugars that are at the base of the food web due to increase water temperatures; the coral dies and disrupts the feeding structures; coral reefs also serve as nursery for marine species and therefore affect the pelagic zone of the ocean.

10. Deforestation - Cutting down of trees.

11. HIPPO
Habitat Loss
Destroying habitats, organisms die due to this.
Invasive Species
An organism that is not native to an area is introduced and competes for food with the native species
Ex. Zebra mussel in lake erie

12. Pollution
Harming the environment with toxins or gases.
Population Growth
Increasing human population; need more resources
Ex. Asian countries
Over Consumption
People taking more than they need
Ex. China consuming many endangered species

13. Current rate of species extinction?
18-50 species a year
The science of protecting species.
Conservation biology
What countries are the top importers of illegal wildlife?
U.S., China
Why are endangered species sold around the world?
- food, clothing, pets, traditional medicines.

14. What are specialist organisms?
Organisms that eat only one thing, they have a special role in the environment, keeping what they eat in check. If they die out the ecosystem will change affecting other organisms.
What is a keystone species?
- Species that is important in keeping the ecosystem stable, when the species is removed the ecosystem changes drastically.

15. Trophic cascade
When a species is removed the ecosystem changes drastically.
What is the current rate of consumption around the world?
- 30% more than what the world can regenerate.
