A forest is an ecosystem in which different species of trees, insects, shrubs, and animals interact. How would the sustainability of a forest ecosystem be affected if the biodiversity of the forest increased?

• The sustainability of the forest ecosystem would decrease because there would be more interactions between different species.

• The sustainability of the forest ecosystem would increase because there would be fewer interactions between different species

• The sustainability of the forest ecosystem would decrease because there would be fewer interactions between different species.

• The sustainability of the forest ecosystem would increase because there would be more interactions between different species.

Sustainability is defined as the ability of an ecosystem to survive over time. How does biodiversity affect the sustainability of an ecosystem?

• It introduces fewer new species of organisms.

• It helps to keep the ecosystem balanced.

• It allows organisms to avoid competition.

• It creates a constant state of change.

Scientists collect data regarding Earth's surface temperature over the last 900,000 years using direct and indirect methods. If they construct a graph of this data, which statement best describes the graph?

• The graph would start low, and then curve upward significantly to show a rapid rise in average temperatures.

• The graph would have a fairly straight line with a sharp curve upward to show recent rising temperatures

• The graph would have both highs and lows to show the periods of warm and cool temperatures.

• The graph would show stable temperatures followed by a sharp curve down as temperatures cooled

The Edwards Plateau in west-central Texas is home to a diverse group of bats, reptiles, and birds. How does the biodiversity of the Edwards Plateau affect the sustainability of local ecosystems?

• The variety of interactions among the different species helps the ecosystems remain sustainable

• The variety of interactions among the different species prevents the ecosystems from being sustainable.

• The uniformity of interactions among the different species prevents the ecosystems from being sustainable.

• The uniformity of interactions among the different species helps the ecosystems remain sustainable.

Where is the "GOOD" ozone located?

• troposphere

• stratosphere

• mesosphere

• thermosphere

Which is true about ozone formation and destruction?

• Its formation and destruction is an example of a dynamic process in nature.

• It forms when a free oxygen atom reacts with a molecule of oxygen.

• UV radiation breaks up ozone by splitting off an oxygen atom.

• Ozone cannot reform once it absorbs UV radiation.
