Because of this, plants in the understory of the tropical rainforest have large leaves
competition for sunlight
Rainforests have high/warm temperatures and high _______.
precipitation
This biome has more species in it than all other biomes combined
Tropical rainforests
In the dark aphotic zone this cannot occur
photosynthesis
Plants called this, seasonally drop their leaves when it is cold or dry
Deciduous plants
This biome is defined by its low precipitation
Deserts
Due to the consistently cold conditions, taigas are characterized by these needle bearing trees
conifers, evergreens
Nutrient availability becomes higher the closer you get to this
the coast (the coastal zone)
Animals living in areas that have periods of wet and dry seasons will do this when it is dry.
estivate or migrate.
Because of the large mammals that live in them, the soils of tropical grasslands are often like this
compact
Large mammals, like elk, do this when the brief summers end in the tundra
migrate
This area is characterized by changes in water depth due to changing tides
intertidal area
Plants living in dry environments will have this substance outside their leaves to prevent water loss
waxy outer covering
A layer of permanently frozen subsoil found in the tundra
permafrost
Small mammals living in temperate grasslands do this in order to avoid predation
burrow, camouflage
This zone of the open ocean is where most photosynthesis on Earth occurs.
The photic zone
Some plants living in tropical shrublands depend on this to germinate
fire
Because of the seasonal leaf loss, temperate forests often have ____________ soil
rich, fertile, nutrient full
Many plants in grasslands spread their seeds this way
by the wind
Wetlands are important because they help to filter this from the water
pollutants
