• 20 degrees Celsius
• 35 degrees Celsius

A population of green iguanas lived on a tropical island. Originally, most of the iguanas had feet without webbing between their toes and a long round tail. A few iguanas had webbed feet and a short, flat tail. As the years passed, the island became smaller and smaller because of flooding. Even the land areas were dotted with ponds and pools. The iguanas had a hard time finding the food they normally ate. To survive, the iguanas had to swim from island to island to find food. How would you expect the iguanas to look many years after the island flooded and food became harder to find?

• The iguanas will look the same but there will be less of them.
• There would be more iguanas with webbed feet and flat tails.
• There would be fewer iguanas with webbed feet.
• The iguanas would no longer be green.

Wildfires are frequent In the Great Basin shrub steppe. Every time there is a fire outbreak, much of the natural vegetation is destroyed. What is the MOST LIKELY impact of fire on this ecosystem?

• A drastic reduction in the animal population due to migration or death by starvation.
• No impact, because the plants have only been temporarily removed from the ecosystem.
• There would be no rainfall because there are no trees or shrubs in the region.
• Non-native plants and animals would migrate into the region.

In a drought, sufficient water is not available for the uptake of water into trees. This directly affects the process of _____________________. Without this process, ample oxygen is not placed into the atmosphere for living things to undergo _______________________.

• oxygen, carbon dioxide
• carbon dioxide, oxygen
• photosynthesis, respiration
• respiration, photosynthesis

A team of scientists examining the effects of drought conditions on fish populations assembled the data shown. The data are collected from automated stations that monitor water levels in a stream. The scientists suspect that one of the automated stations may be malfunctioning. Based on the data shown, which monitoring station is most likely malfunctioning and reporting erroneous data?

• Station A
• Station B
• Station C
• Station D
