1.2 - 1.3 terrestrial + aquatic biomes

tundra characteristics

short growing season, permafrost, short vegetation, cold desert, fragile biome

taiga characteristics

short trees, pine trees (waxy leaves conserve water) which leaves to acidic soil, nutrient poor soil

grassland characteristics

not enough rain for trees, nutrient rich soil, fire

temperate seasonal forest characteristics

deciduous (lose leaves), nutrient rich soil

temperate rainforest characteristics

coastal biome, wet, pine trees lead to acidic soil, logging

shrublands characteristics

little water, fire, vinyards, nutrient poor soil

desert characteristics

hot and dry, nutrient poor soil

savannah characteristics

warm and wet, nutrient rich soil, fire

tropical rainforest characteristics

warm + wet, high productivity rate, nutrient poor soil, competition for sunlight, year round growing seasom

rivers and streams characteristics

high DO (dissolved O2), no plants, rocky bottom

lakes and ponds zones

littoral = edges w/ plants, limnetic = part of water w/ light, profundal = part of water w/ no light, benthic = bottom, terminal lake = end of river (saltwater)

ocean zones

littoral/intertidal = edge w/ plants, pelagic, nertic = most life, photic = light, aphotic = no light, benthic = bottom

coral reef characteristics

high biodiversity, high productivity

ex) great barrier reef

open ocean characteristics

low productivity per unit area, high total productivity

estuary

where the river meets the ocean

97% ocean

3% fresh

1% surface and ground

which terrestrial biome has the highest net primary productivity?

tropical rainforest

which terrestrial biome has the highest primary productivity per unit area?

tropical rainforest

which biome contains a nutrient-rich environment created by falling leaves + trapped organic materials from large trees that provides the ecosystem service of filtering pollutants from water

freshwater wetlands

which biome is found in shallow waters off the coastline and is Earth’s most biologically diverse marine biome?

coral reefs

which biome is characterized by fast-flowing water that can originate from underground springs or runoff, which carries sediment and organic material?

rivers
