Primary producers in the deep sea use energy from Primary producers are present in every biome, including the deep sea. How can
chemical reactions to drive the reduction of there be primary producers in the deep sea when sunlight does not penetrate to
CO<sub>2</sub> to organic compounds. these depths?
Fitness is decreased because the seeds are not Wheat is a group of grass species. Cultivation originated in the eastern
dispersed. Mediterranean about 10,000 years ago. In comparison to closely related wild
grasses, cultivated wheat has shorter stalks and fewer, larger seeds that are firmly
attached to the stalk (e.g., they don't easily blow away in the wind). These changes
are useful for humans, but will they increase or decrease the fitness of cultivated
strains of wheat in their natural environment?ore
fertilizer Human impact on the nitrogen and phosphorus cycles happens primarily through
our use of:26.10
As temperatures have warmed, flowering occurs earlier in Using records taken by Henry David Thoreau in the 1840s, scientists have
many species. documented what pattern of change in flowering plants around Boston,
Massachusetts?
10% About how much of the nitrogen added to croplands ends up in food?
Nitrogen Gas The source of nitrogen in nitrogen fertilizer manufacture is:
50%; 40-50% Clearcutting for grazing and croplands has destroyed more than ___ of the
preindustrial area of tropical rainforest and, left unchecked, deforestation over the
next century could eliminate _ of all tree species in the Amazon forest.
30 Oceans are about ___ % more acidic than they were in the 1960s.
One-third; 40 _____ of all amphibian species are threatened with extinction, and more than ___ %
have undergone significant population declines in the last decade.
, one-third About___ of the CO2 produced by humans during the past century has been
absorbed by the ocean.
habitat loss, pesticides and other toxins, and fungal Amphibian population declines have been linked to:
disease.
More information is needed about, for example, the A college student walks down New York City's Fifth Avenue at 8:00 AM. She is late

accurately determine her ecological footprint in both a larger ecological footprint when she was walking or when she was on the bus?
situations.
are least able to change their flowering time. A number of plant species have declined in abundance around Boston,
Massachusetts, since Thoreau's time. These tend to be the plants that:
a species that is a habitat specialist and lives at the If you were studying the effects of climate change on the geographic ranges of
highest elevations species living in the mountains and your climate records showed that mean
temperatures were increasing, which species would you be MOST concerned
about from a conservation standpoint?
water vapor and methane In addition to carbon dioxide, which of the following are also considered to be
greenhouse gases?
Yes. Nitrogen is obtained from nitrogen gas, which is in Compared with nitrogen, do we need to be concerned that we may run out of
virtually infinite supply. Phosphate is mined from phosphates?
sedimentary rock and deposits are limited.
a sharp spike in population levels in the spring, when You track aquatic coastal levels of nitrogen and phosphorus at high latitudes and
light levels are higher; not much of a response in winter notice a sharp increase in the winter and then again in the spring. What do you
expect the effect of these nutrient increases will be on the plankton populations?
Decrease the volume of nitrogen used in agricultural Dead zones have been documented in many areas. These dead zones are
areas near dead zones. increasing in size each year. Which of the following would be one of the ways to
decrease the size of these dead zones?
low; high aerobic respiration An abundance of nitrogen (N) and phosphorus (P) in an aquatic environment
leads to _____ levels of dissolved oxygen due to _.
acid; down Carbon dioxide combines with water to form a weak ___ ; this has caused the pH
of seawater to go __ _.
cushions organs from hard blows and allows body to What are the advantages of having a true coelom?
twist without twisting organs
mirror symmetry that results in a distinct head and tail and Bilaterians are distinguished by:
one plane of symmetry.
blastopore that becomes an anus. A deuterostome is distinguished by a(n):
organ systems What feature of animals enabled them to diversify in ways that plants, fungi, algae,
and protozoans have not?
