2.

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?

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?

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?

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?

This question has two parts.

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?
