In a grassland ecosystem, a severe drought causes a significant loss of plant life. How would this change affect the rest of the ecosystem?

Stability increases as predators consume more prey.

Stability does not change because primary consumers will increases to make up for the loss.

Stability decreases due to reduced availability of resources.

Purple loosestrife is an invasive flowering plant species now found in North America. In an effort to control the purple loosestrife, biologists tested and released three beetle species to use as a biological control of the plant.
Which result is an unintended negative consequence of releasing these beetle species into the environment?

There will be an increase in the available habitat for non-native plant species.

There will be an increase in competition for food resources among all beetle species in the habitat.

There will be an increase in the population numbers of native beetle species in the habitat.

Kelp forests are critical ecosystems that provide habitats to a variety of animals, including sea urchins, sea stars, sea anemones, crabs, jellyfish, snails, and fish. They also provide hunting grounds for mammals, including sea otters, sea lions, seals, and many different birds. In recent years scientists have documented an increase in shark attacks on sea otters in and around kelp forests.
Which consequence is most likely to occur in kelp forests as a result of increased predation of sea otters?

Kelp forests will become less stable as sharks will also eliminate the prey of the otters.

Kelp forests will become more stable as sharks replace otters as the top predator in the food chain.

Kelp forests will become less stable due to the increase in the size of the otters' prey population.

A large section of the Amazon rainforest has been cleared to make way for agriculture. This deforestation has led to habitat loss for many species, including jaguars, macaws, and poison dart frogs. Additionally, the removal of trees has reduced the amount of carbon dioxide absorbed from the atmosphere.
Which of the following is the most likely consequence of this environmental change?

Biodiversity will increase as new species move in to replace those lost.

Biodiversity will decrease as the ecosystem becomes less stable.

Deforestation will have no significant impact because tropical species can easily adapt.

The San Marcos salamander, Eurycea nana, is a light reddish-brown translucent salamander about 2-5 cm in length. E. nana is found only in Spring Lake and a portion of the San Marcos River.
Which human activity would most likely decrease the ability of the salamanders to survive?

Public transportation that reduces the number of automobiles that contribute to pollution runoff into the river

Increasing water consumption that decreases the flow of clean water from the springs that feed the river

Tourism that helps fund the educational programs related to river ecosystem conservation

This question has two parts.

East Texas has a wide variety of frog species that take advantage of different resources in the ecosystem, by eating different foods, choosing different ponds, and mating at different times of the year.

Part A
How does the biodiversity of frog species MOST CLOSELY affect the stability of the ecosystem?

By making the ecosystem more vulnerable to population losses

By reducing the ability of individual organisms to adapt to changing conditions

By increasing the ecosystem's ability to stay healthy when conditions change

The population of an invasive crab species, Callinectes sapidus, is rapidly increasing along coastal Europe. This aggressive, fast-growing omnivore reproduces quickly and is causing the extinction of many native species.
Which statement BEST describes the effect of a native species' extinction on local ecosystem biodiversity and stability?

Extinction leads to decreases in biodiversity and increases in stability.

Extinction leads to decreases in biodiversity and decreases in stability.

Extinction leads to increases in biodiversity and increases in stability.
