Biomes in APES

This biome has acid soils. Coniferous Forest/Boreal Forest/Tiaga the dropped needles from the trees cause this.
This forest biome has very little nutrients in the soil. Rainforest-decomposition is so rapid that nutrients are found in trees. Ironically these are clear-cut for agriculture.
Has soil extremely rich in nutrients and humus. Temperature deciduous forest. Deciduous means to drop leaves. That leaf litter accumulates on forest floor and decomposes slowly.
Most disturbed terrestrial biome. temperate deciduous forest.
Has permafrost(layer of frozen soil) all year round, essentially a cold grassland. Tundra
Most animals are grazers here Tropical grassland-savannah.
Ecosystems here are fragile and soils take hundreds of years to recover from disturbance due to lack of water, nutrients, species diversity and slow plant growth. Deserts
They persist do to grazing, drought and fire which prevent many trees and shrubs fro growing there. Grasslands
deep, fertile soil due to grasses that die seasonally temperate grasslands ex)prairies
under snow is carpet of spongy, grasses and lichens Tundra
winter are long, dry and very cold-summers short and cool-shorter daylight hours in northernmost Coniferous forest
In general, precipitation is low and scattered unevenly through year and the nights can be quite cold (heat from soil radiates into atmosphere quickly). Deserts
Type of trees found in the rain forest broadleaf evergreen
Type of trees found in temperate deciduous forest deciduous trees. like the maple, that drop their leaves
vegetation varies with climate and latitude
succulent plants, like cacti, have these adaptations no leaves, store water, and open pores for carbon dioxide at night only
phytoplankton drifting plants and algae
zooplankton protozoa and jellyfish are examples. drifting animals that feed on phytoplankton.
nekton strongly swimming consumers like turtles
benthos bottom dwellers like oysters
fire that burns underbrush and ground material, it has ecological benefits such as freeing up mineral nutrients in decomposing material and releasing seeds from pine cones surface fires
destructive fire that leaps from tree to tree crown fires
If fires are suppressed then... there is a greater chance that the fire intolerant species& underbrush will build up enough and more destructive crown fire will result, this an cause soil erosion, death of wildlife, destroy all vegetation in it's path and move on to human structures.
Make sure you know the ecological and economic services each biome provides and how humans have disturbed them!
