Imagine the birds that eat peppered moths went extinct. What would happen to the peppered moth population?

Wildebeest are species of antelope found in southern Africa. The wildebeest herd in Serengeti National Park, Tanzania, is the largest herbivore herd on Earth. Scientists began monitoring the sizes of the Serengeti's large mammal populations in the 1960s. Over the next few decades, they noticed something unusual: the wildebeest population was increasing at a rate much faster than before. The scientists determined that this increase was due to several factors. One factor was a vaccination program that eradicated rinderpest, a viral disease that kills wildebeest. Based on the figure, what kind of population growth model would you use to represent wildebeest (circles) populations? wildebeest zebra 1960 1970 1980 1990 2000 year Figure 1.

Why are species that live at the tops of mountains at increased risk of extinction due to climate change?   a. The colder temperatures at the tops of mountains gradually increase, and the species at the tops of the mountains are displaced by species at lower elevations moving up.    b. The species at the tops of the mountains are adapted to moving up and down the mountains and species at lower elevations are displacing them as they move down the mountains.    c. The species at the tops of the mountains are adapted to lower oxygen and climate change increases oxygen content in the air.    d. Species at the tops of mountains do not have the genetic diversity for adaptation that lower-elevational species do. Therefore species at the tops of the mountains are more likely to go extinct.

imagine that you have a population of monkeys the variety within the species allows for monkeys to be long tailed or tailless; carnivorous or herbivorous; and brown or blonde furred. Describe an example of an environmental change to happen to these monkeys that over many generations?

What will likely happen to the rat population if the grasshopper population decreases

Tigers are solitary animals that require vast amounts of forest landscape as their territory to roam. In order to protect one tiger, we must conserve around 25,000 acres of forest. With poaching and deforestation threatening their survival, what are possible solutions to bring tiger populations back from the brink of extinction?

Sea stars prey on sea urchins in coral reef ecosystems and are known as a keystone species. What does this mean?

The video discuss some of the factors that allowed lionfish to expand throughout the Atlantic region. Which of the following reasons were given for why the lion fish population has been able to expand so rapidly? A. The Atlantic region has fewer parasites that attack lionfish. B. The lionfish outcompete native fish for food. C. Lionfish are able to breed more frequently the native fish. D. Atlantic predatory fish don't eat lionfish. E. None of these
