Which best describes what is occurring in this population of squirrels?
Scientists have a theory about the relationship between climate and biodiversity. Which best describes this theory?
Interactions between organisms and their environment impact the organism’s overall population. The jaguar Panthera onca is the largest cat in North America. It is found in areas across the Southwest, including Arizona, New Mexico, and Texas. It is a carnivore that has powerful jaws and sharp teeth and preys on fish, turtles, and many smaller mammals.

The burrowing owl is found in dry, open areas such as grasslands, prairies, savannas, deserts, farmlands, golf courses, and urban areas throughout most of western United States and Florida, Central America, and most of South America. It makes its home in burrows of other animals and primarily eats insects and small rodents. As humans build more cities, nearby burrowing owl habitats change due to destruction of burrows and loss of prey. Which is the least likely outcome of the habitat changes that are described?
Ground squirrels are found in many areas of the United States. They live in underground burrows and are often attacked by birds of prey, coyotes, and bobcats. Which of the following is a limiting factor for a ground squirrel population?

The Serengeti plains are part of the African savanna ecosystem and are home to a variety of different species of plants and animals.
