Welcome

1. Welcome • Please sign in at the front. While you’re at it, why not have a piece of candy. • Please be aware that you will be put into a team: 1, 2, 3, or 4, so please go ahead and break yourselves up into these teams so that we can get started quickly. If anyone comes in late, please take them into your teams. Don’t just leave them hanging.

2. Getting started • This review will be posted on my SI resources site (See Vista), so there’s no need to write everything down. (unless you just want to) • This session is much different than a regular SI session: this is a fast-paced review rather than going into the material in depth. • Shameless plug: People who come to my SI sessions typically do better on their tests. Please come, having more people generally makes the sessions more enjoyable.

3. Rules • Each team will have a chance to work together to answer questions in order: Team 1, 2, 3, 4 • If the team cannot answer all parts of an original question, the question will be passed to the next team (this is separate from the bonuses). • The winning team may have 4 pieces of candy each, 2nd place gets three, 3rd and 4th get 2. • Please put your notes away unless you are writing in them, no points will be awarded for finding info in your notes.

16. A relationship in which one organism depends on another for nourishment or some other benefit while simultaneously doing the host harm • Parasitism * • Mutualism – relationship in which both organisms benefit • Competition - A relationship in which multiple organisms seek the same limited resource Back toGame

17. Category II for $200 True or false: Intraspecific Competition takes place with members of the same species

18. True: Interspecific competition on the other hand, takes place between members of different species. A good way to remember is Interspecific – between Intraspecific - among Back toGame

30. Category IV for $100 The golden toads, which lived in a Costa Rican cloud forest, became extinct in 1990. What was the cause?

31. Climate change: The increase in temperature caused the clouds to rise, making the forest to dry for the toads eggs. Back toGame

40. Labs - 100 From which two resources do Georgians get the majority of their electricity? • Coal and solar power • Nuclear and coal • Coal and natural gas

41. Coal and Natural gas

42. Labs - 200 What is allometry, and how was it used in your labs?

43. Allometry: "the measure and study of relative growth of a part in relation to an entire organism or to a standard". (Sampling and using equations based on similar subjects to make predictions). You used the diameter of trees to estimate their biomass.

44. Labs - 300 Name two ways to reduce the amount of carbon dioxide in the atmosphere

45. 1. limiting how much CO2 we emit into the atmosphere as we burn fossil fuels, use trees, etc. 2. increase the rate at which we absorb CO2. - carbon sequestration (usually by plant life)

46. Labs - 400 Removing an atom of carbon from the atmosphere also reduces CO2 levels. Why?

47. By conducting photosynthesis, plants take in CO2, and release O2, causing there to be less CO2 in the atmosphere, and more oxygen molecules.
