Rain Forest
Conditions vary at each forest level. Different communities evolve to occupy
each habitat.

Deciduous Forests
Stratification also exists within deciduous forests, Less tree biodiversity than found in rain
forests.

Forest Floor
Decaying leaves provide a deep, rich layer of soil.
Insects and other invertebrates live in the soil and debris, feeding on abundant organic matter

Deciduous Forests
Winter AdaptationsMigration
○ Many birds fly south to find warmer temperatures and food
Hibernation○ Some mammals reduce their metabolic
activity so that they do not need as much food for energy.

Recall: Snow acts
as an insulator

Coniferous Forests
Some animals thrive in the winter conditions.

Tundra caribou
Body hair traps air that acts as insulator. migrate during the winter in search of food and water
Wolves Take advantage
of caribou
movement patterns prey on burrowers.

Deserts
Recall: water is very limited.
![Page 15: Rain Forest Recall Stratification Niche Occupation Two factors create enormous biodiversity in animal species. Stratification Diversity of tree species.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649eba5503460f94bc1b03/html5/thumbnails/15.jpg)
Desert Reptiles
Have thick, scaly skin that prevents water loss

Desert Amphibians
Burrow in ground and sleep through the dry season.

Nocturnal BehaviorActive at night
○ Hunting/feeding at night avoids the daytime heat.

Temperate Grasslands
Steppes Prairies

Adaptations During colder months, some animals
hibernate in search of food and warmer temperatures.
During warmer months, large herbivores are supported by the abundant grasses.
Many smaller animals burrow to avoid fires and extreme temperatures throughout the year.

Tropical GrasslandsAKA Savanna
Animal populations concentrate around streams and watering holes. Recall: streams and watering holes are
sources of water and more vegetation.
vertical feeding patterns: Animals eat vegetation at different heights to
avoid competition for limited resources.

More Adaptations
Many animals, such as zebras, migrate long distances in search of water.
Predators follow their migration patterns.
