Multiple Choice

Frogs are amphibians. Like all amphibians, frogs are cold-blooded, meaning that their body temperatures change with the temperature of their surroundings. When temperatures drop, some frogs dig burrows in the mud at the bottom of ponds. They hibernate in these burrows until spring, perfectly still and barely breathing. Frogs can be found just about anywhere there's fresh water, on all continents except Antarctica. Though they thrive in warm, moist tropical climates, frogs also live in deserts and high on 15,000 foot mountain slopes. The Australian water-holding frog is a desert dweller that can wait for seven years for rain. It burrows underground and surrounds itself in a transparent cocoon made of its own skin. Frogs' skin is critical to their survival. Through it, they drink and breathe. Frogs don't swallow water; they get the moisture they need through their skin. And although frogs have lungs, they rely on the oxygen they absorb through their skin, especially when they're underwater. Frogs must keep their skin moist. Otherwise, oxygen does not easily pass through it and the frog suffocates. Even though frog skin secretes a mucus that helps keep it moist, their skin tends to dry out easily, which is why they usuallystay near bodies of water.

Consider the bar graph comparing the number of frogs in four different habitats. Based on the information above about frogs, what is the MOST LIKELY factor limiting the frog population?

Multiple Choice

Bill is a fisherman on the Gulf Coast, and he has noticed that over the past several years, the shrimp population has grown smaller. He wants to come up with a way to keep fishing for shrimp, but at the same time, he doesn't want the shrimp numbers to drop any further.

• The squirrel will adapt to less food.

• The squirrel will not be affected at all.
