APES Chapter 3 Quiz Prep
1. Growth rates at which the amount doubles in a fixed unit of time is called exponential growth.
2. Changes that tends to stabilize a system is called negative feedback.
3. Change that tends to destabilize a system is called positive feedback.
4. The lessons of Amboseli National Park teach us:
III. Continued wet-dry cycles change soils, the distribution of plants, and the abundance of animals.
5. The principle of environmental unity states that everything affects everything else; all systems on the planet inherently affect each other.
6. Considering inputs to a pool and outputs from it, the pool will be in steady state when the amount of inputs is equal to the amount of outputs.
7. The figure above illustrates the amount of time vs the locust population. As time progresses, the locust population exponentially increases.
8. This is an example of positive feedback because as time increases, the locust population increases as well.
9. Doubling time=70/%, where the rate is not converted to decimal places.
70/5, which is equal to 14. So, it would take 14 class days to double the # of students.
10. ART=s/f, where s is total, and f is the rate.
ART=1200/600, or 2. The ART is equal to 2 months.
11. This is an example of uniformitarianism because past events, such as millions of years of sediment deposit, influence future ones.
12. The region of the Earth where life exists is known as the biosphere.
13. Amboseli National Park suffered a serious loss of the woodland habitat because of changes in rainfall and soil composition. These were detrimental towards the well-being of these trees, and as a result, they suffered.
14. The Gaia Hypothesis says that the different aspects of the Earth, such as the environment, the atmosphere, and the climate are all impacted by the biota; we directly influence these Earthly attributes.
15. An example of a problem of these long residence timed systems is the issue of
