The soil in Tropical Rain Forest is what?
Where are all the nutrients contained in the tropical rain forest?
trees and vines

quickly recycled by decomposers and taken up by plants
What happens when the forest in the Tropical Rain Forest are cleared?
they leave behind nutrient-poor soils that can only support crops for a short period of time

dark and damp
shorter trees and plants in the Tropical Rain Forest make up the what?
The under-story plants and trees in the the Tropical Rain Forest compete for what?
What allows for for maximum light absorption for the under-story in the Tropical Rain Forest ?
large, flat leaves
Plants in the the Tropical Rain Forest tend to have what?
large, flat leaves and shallow roots
bulges at the base of the trees that help stabilize them
grow from the forest floor, twisting around tree trunks to reach light higher in the canopy
plants that grow on other plants instead of soil, take advantage of its hosts height to get access to sunlight

Bromeliad and Orchids
Which biome supports the most animal species?
Tropical Rain Forest
Animals in the Tropical Rain Forest tend to be what?
Why do plants have a problem with reproduction in the tropical rain forest?
Because plants pollinate by wind, they struggle with pollination because the rain forest receives little to no wind. However, so many rain forest plants have developed elaborate flowers that are brightly colored or have distinguishing smells to attract pollinators.
What an example of a plant that is brightly colored and has a distinguishing smell to attract pollinators?
Corpse flower, it smells like a dead rotting body to attract flies to pollinate them

Tropical Dry Forest are also called what?
tropical deciduous forest
when trees lose their leaves and cease photosynthesis part of the year
Why is the seasonal loss of leaves beneficial in dry climates in the Tropical Dry Forest?
it enables trees to prevent water loss
What kind of trees are most in Tropical Dry Forest?
What kind of adaptations do plants and animals exhibit in the Tropical Dry Forest that enable them to survive during the dry season?
waxy leaf coating, deep roots, estivation, and migration
prevents drying out
waxy leaf coating
Allow plants to seek water that is deeper in the ground
a deep sleep-like period of dormancy in animals, similar to hibernation but triggered by HEAT and DRY CONDITIONS rather than cool temperatures

Characterized by tall evergreen trees, such as cedars, spruces, Douglas fir and hemlocks, that don't lose leaves annually
temperate rain forest
Conifers have ______-______ leaves that are coated with thick, waxy substance that helps prevent what?
needle-like , water loss
Whats better for trees in the temperate forest or in any forest in general, being tall or short?
tall because they have access to more sunlight

Boreal forest has a ______ species diversity
low (not a lot of species live there)
What kind of soil do they have in boreal forest?
nutrient-poor, slightly acidic
Boreal forest have _____-, cold winters, and _____ , cool summers
Name a coniferous species that exists in boreal forest?
Coniferous trees in the boreal forest adapted to the harsh, snowy conditions how?
trees with waxy needles and conical shape
prevent water loss which is a good thing because the ground is frozen and trees can take up water from the ground
Many conifers have what kind of relationship with fungi?
symbiotic relationship, which allows them to make use of scarce nutrients
