Deciduous Forests Answers

The thick bark of deciduous trees serves two purposes. It insulates the tree during winter, providing protection from cold temperatures. It also helps deciduous trees retain water more effectively, allowing the trees to survive periods of less precipitation.

Deciduous forests contain deciduous trees, or trees that lose their leaves once a year. They have four distinct seasons and experience 30 to 60 inches of precipitation annually. Precipitation occurs throughout the year, rather than being concentrated in one or two seasons.

Deciduous trees lose their leaves in the fall to aid in their survival during the winter months. Most of the water and nutrients plants use are consumed by the leaves. By shedding their leaves, deciduous trees are able to survive off stored nutrients during 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.

The wood frog has adapted to life in the deciduous forest by being terrestrial, being camouflaged, and hibernating in the winter.

Animals in deciduous forests survive winter in several ways. Some hibernate or become less active to conserve energy, some migrate to warmer areas, and others store food. Many grow thicker fur or feathers for insulation, while some change their diets to eat whatever food is available.

A wood frog can survive winter by sheltering beneath leaf litter and allowing much of its body to freeze. It builds up glucose, which helps protect its cells from damage caused by ice. While frozen, its heartbeat and breathing may stop, and they resume when it thaws in spring.
