Why are burrowing animals and ground-dwelling birds common in grasslands?
Burrowing animals and ground-dwelling birds are common in grasslands because there are very few trees in which birds and animals can take shelter. Burrowing also affords animals some protection from the fires and high temperatures that are common in grasslands during the dry season.
What adaptations does a wood frog have that enable it to survive in deciduous forests?

How have savanna plants adapted to long periods of drought?
Savanna plants have adapted to the long periods of drought in a variety of ways. Some savanna plants have the ability to store water. Other plants have long roots which allow them to reach the water table.
Contrast the different ways bromeliads and pitcher plants acquire nutrients from animal sources.
By collecting rainwater in their leaves, bromeliads create mini-ecosystems that house other small animals. When they die, these organisms decompose and the bromeliad benefits from the nutrients. Pitcher plants, meanwhile, actively trap insects and other small animals in their pitchers. The bromeliads are an example of mutualism while pitcher plants are predators.
How have animals in deciduous forests adapted to survive the winter months?
Animals in deciduous forests have adapted to survive the winter months in different ways. Some animals migrate to warmer climates during the winter months and return to the deciduous forest when the weather is warmer and resources are more available. Other animals hibernate during the winter. They eat more during the warmer months, storing energy as body fat. During the winter, their metabolisms are slowed, allowing them to live off less energy.
