* The scientific study of the interactions between organisms and their environment is called _____. | ecology p.850 |
*The intensity of sunlight that hits the Earth in any given place or season is determined by the ____. | angle that the sunlight strikes the surface of the Earth (Sunlight strikes the Earth most directly at the equator and the angle becomes lower as you move away from the equator. Winter is caused by the fact that due to the Earth's tilt, the angle that the sun strikes the parts of Earth experiencing winter is much lower than when it strikes the same places in summer. A 90 degree angle would be straight overhead. Many people falsely believe that the seasons are caused by the elliptical orbit of Earth around the sun. In the northern hemisphere, the Earth is actually closer to the sun in the winter) p.852,  |

* Oceans cover about ____ of the planet's surface. | 75% p.859 |
* Any organism that is not strong enough to swim against the current (and therefore basically floats and drifts) is referred to as ______. If they are photosynthetic, they are called _____. If they are heterotrophs, they are referred to as ____. | plankton, phytoplankton, zooplankton pp. 860, 861, 862, 885&886 |
* The different seasons are caused by ______. | Earth's tilted axis (Sunlight strikes the Earth most directly at the equator and the angle becomes lower as you move away from the equator. Winter is caused by the fact that due to the Earth's tilt, the angle that the sun strikes the parts of Earth experiencing winter is much lower than when it strikes the same places in summer. A 90 degree angle would be straight overhead. Many people falsely believe that the seasons are caused by the elliptical orbit of Earth around the sun. In the northern hemisphere, the Earth is actually closer to the sun in the winter) p. 853,  |

* Which type of population growth does this graph show?,  | Logistic growth p.869,  |

* At which point in the graph below is the population growth rate the highest?,  | The population growth "rate" is the highest at point B. (You can determine the growth rate by finding the slope of the line tangent to the curve. Remember, slope = rise divided by run. In this case, the rise is the current population. The run is time.

* Which survivorship curve would represent the human species? Which would represent a typical fish species?,  | Humans would be type I (due to their fairly high infant survival rate) Fish would be type III (because most lay many eggs and generally don't guard them or protect the juveniles, so most fish are eaten when they are small, if they even manage to make it out of their egg) p. 866,  |
