The Florida Panther is a large cat that is native to the southern parts of Florida. Recently, the panther's main food source, rabbits, have been infected with a deadly disease that only affects rabbits. How would this most likely affect the population of panthers in the coming years?
The panther population will decrease since they won't have access to as much food
The panther population will not be affected because they will adapt to eating other food
The panther population will increase because they will produce more offspring to make up the difference
The panther population will decrease because they will contract the disease.

Michael feeds his fish two teaspoons of fish food every day. Over a period of 4 months, the average population is 40 fish. She increases the amount of food to 2 teaspoons per day. After another 4 months, the population is now 65 fish. How is this possible?

As long as Michael keeps giving them more food, the fish population will continue to get bigger

Sea turtles are marine reptiles. They rely on an external heat source, which makes them ectotherms. They are commonly found in waters off the Mid-Atlantic and Northeast United States during the summer and early fall. Typically, they begin to migrate south to warmer water by late October. However, some sea turtles strand along our shores when water temperatures drop rapidly or unexpectedly. This is called “cold stunning.” Cold stunning is similar to hypothermia in humans. Initial symptoms include a decreased heart rate, decreased circulation, and lethargy, followed by shock, pneumonia and possibly death.
Based from this passage, why do sea turtles migrate?
Sea turtles migrate because their food source is more abundant in the south during the fall.
Sea turtles migrate because predators become more abundant in the Mid-Atlantic and Northeast of the U.S. during the summer and early fall.
Sea turtles migrate because humans are fishing more often in the areas where they are commonly found during summer and fall.
Sea turtles migrate because they depend on external sources of heat to help maintain their body temperature.

In 1910, there were approximately 100,000 cheetahs living in the wild. That number has now dropped to less than 10,000 and has drastically reduced the gene pool. What will be the consequence of this reduction?
Competition in the population will increase
Inbreeding will be less frequent among the remaining population
Cheetahs will be more vulnerable to environmental changes
The surviving cheetahs will be better able to adapt.

The number of pythons found throughout the Everglades has increased in recent years. These huge snakes are invasive to Florida and are believed to have been released into the wild by pet owners. Wildlife biologists have attempted to capture and remove these pythons. Which statement best explains the biologists' reasons for removing these pythons from the Everglades?
The pythons could attract other non-native species to the area.
The pythons could adapt to overcome diseases common to native snakes.
The pythons could prey on native organisms and cause native populations to decline.
The pythons could begin to interbreed with native snakes and produce a more successful species.
