Question 44

The reason tropical deforestation is worse than temperate deforestation is because __________.

there's more carbon in the ground in tropical forests

rates of photosynthesis are higher in temperate forests

there's more carbon in the ground in temperate forests

governments in the tropics can't deal with the problem

there's more carbon in the trees in temperate forests

Question 45

The first species to appear in an area undergoing either primary or secondary succession is called a pioneer species.

True

False

Question 46

Tides are driven primarily by:

the density of sea water

surface wind waves

magnetic forces within the Earth

Gravitational attraction by the moon

plate tectonics

Question 47

Ironically, beach erosion is often caused by the very structures built to prevent the erosion in the first place.

True

False

Question 48

Why is the nitrogen cycle especially complicated?

It just is, now stop asking.

It involves multiple chemical form changes.

Because nitrogen tend to bind to complex compounds.

It is complicated by bacterial involvement.

Because Dr. Morris over-complicates everything.

Question 49

Energy enters the ecosystems mainly by the process of

nutrition.

metabolism.

biogeochemical weathering.

photosynthesis.

biosynthesis.

there's more carbon in the ground in tropical forests

rates of photosynthesis are higher in temperate forests

there's more carbon in the ground in temperate forests

governments in the tropics can't deal with the problem

there's more carbon in the trees in temperate forests

Explanation / Answer

44. There is more carbon in the ground in tropical forests.

About 10% of carbon emissions come from tropical deforestation.

45. True.

46. Gravitational attraction by the moon.

47. True

48. It is complicated by bacterial involvement.

It involves multiple chemical form changes.

Nitrogen cycle involves a sequence of biochemical changes beginning from free atmospheric N2 to complex organic compounds and further to simple inorganic compounds and thereby release of molecular N2 back to the atmosphere. This cycle involves both symbiotic and non-symbiotic bacteria.

49. Photosynthesis.
