amount of sunlight for photosynthesis.

Which of these bests demonstrates mutualism between certain types of bacteria and humans?

Intestinal bacteria obtain nutrients from the gut and produce vitamin K used by humans.

Bacteria become resistant to antibacterial medication that humans use for treatment.

Bacteria in improperly prepared food is consumed by humans, causing food poisoning.

In the mid-1980s an aggressive strain of algae known as Caulerpa was accidentally introduced into the Mediterranean Sea when a seaside aquarium cleaned out its tanks. The algae contain a toxin that prevents native herbivores from consuming it. Caulerpa quickly spread over the sea floor, crowding out many species including sponges, corals, sea fans, and lobsters. Which statement explains the most likely impact Caulerpa has had on the biodiversity in the Mediterranean Sea?

Caulerpa became dominant within the ecosystem and reduced the biodiversity.

The presence of Caulerpa within an ecosystem is an indicator of the ecosystem’s health.

The spread of Caulerpa improved the habitat for many species of sea grasses, and increased the biodiversity.

Caulerpa interbred with native species with the same adaptations within the ecosystem.

A small town in the piney woods of East Texas has a soccer field composed of native grasses. The soccer field is mowed once a week. What effect does continual mowing have on the ecology of the field?

Mowing maintains a low species diversity by inhibiting further succession.

Mowing increases the likelihood of nonnative species displacing native species.

Mowing increases the number of species found in the field.

Mowing causes different types of communities to form across the field.

Saprophytes are fungi that feed on dead and decomposing organisms. They secrete enzymes that digest components of cell walls, such as cellulose and lignin. Which statement explains why these fungi are an important part of the biogeochemical cycle?

Saprophytes return organic material to the soil for use by living organisms.

Saprophytes perform gas exchange that assists the cellular activities of autotrophs.

Saprophytes extract minerals from living tissue to recycle them back into the soil.

Saprophytes transport nutrients through the xylem and phloem in autotrophs.

Scientists have observed many types of tropical fish moving beyond their traditional ocean ranges into waters that have historically been more temperate. These fish compete for food with native fish, consuming much from the kelp forests and beds of sea grass. The expansion of the ranges of tropical fish was most likely caused by —

the rising temperatures of ocean waters

agricultural runoff that contributes to dead zones in the ocean

global droughts that raise the salt concentration of ocean waters

acid rain pollution that lowers the pH of ocean waters

In North American forests, two species of birds, nuthatches and brown creepers, forage on the same trees for insects. Brown creepers feed on insects found near the bottom of the tree trunk, while nuthatches feed on insects in the top part of the tree. The difference in foraging behavior most likely affects the nuthatches and brown creepers by —

reducing competition between the birds for resources

allowing the birds to avoid many types of predators

preventing the birds from interbreeding with each other

establishing dominance between the birds for nesting sites

The lionfish is a non-native species that is a threat to ecosystems in the Atlantic and Caribbean Oceans. They rapidly reproduce and can destroy massive amounts of coral reefs in a short time period. Which statement best explains why the non-native species is more likely to survive than native
species?

The native species has acquired an immunity to harmful organisms

in the ecosystem.

Both the native and nonnative species are competing for food sources in the ecosystem.

The non-native species has no natural predators in the ecosystem

Both the native and non-native species are prey in the ecosystem.

The photograph below shows a snow-covered spruce forest. A year ago, this spruce forest experienced a mild winter. This year, the spruce forest is experiencing an extremely cold winter. How will the environmental change most likely impact the stability of this ecosystem?

The colder temperatures will cause the spruce forest to maintain the same level of stability as the number of large predators will remain constant.

The colder temperatures will cause the spruce forest to become

more stable, as the number of spruce trees in the forest will steadily increase.

The colder temperatures will cause the spruce forest to become less stable, as the number of insects will steadily decrease.

The colder temperatures will cause the spruce forest to alternate back and forth between being stable and unstable, as the number of shrubs will increase, then decrease.

Legumes, a family of plants with fruits or loments, have structures called nodules on their roots. These nodules contain nitrogen-fixing bacteria that convert free nitrogen from the air into ammonia, which is utilized to make proteins within the plant. What would be the long-term effect of the loss of nodules containing nitrogen-fixing bacteria to the legumes and their ecosystem?

It would result in healthy legumes, a decrease in free nitrogen in the air, an increase in legume-eating herbivores, and an increase in consumers that eat legume-eating herbivores.

It would result in the death of legumes, a decrease in free nitrogen in the air, an increase in legume-eating herbivores, and a decrease in consumers that eat legume-eating herbivores.

It would result in healthy legumes, an increase in free nitrogen in the air, a decrease in legume-eating herbivores, and an increase in consumers that are legume-eating herbivores.

It would result in the death of the legumes, an increase in free nitrogen in the air, a decrease in legume-eating herbivores, and a decrease in consumers that eat legume-eating herbivores.
