TUNDRA TAIGA(Boreal Forest) TEMPERATE RAINFOREST TEMPERATE DECIDUOUS FOREST TEMPERATE GRASSLAND TROPICAL SAVANNA AND GRASSLAND – “Tropical Woodland” or “Chaparral”TROPICAL SEASONAL FOREST TROPICAL SEASONAL FOREST TROPICAL RAINFOREST Desert

CLIMATE GRAPHS: “AN ECOSYSTEM’S FINGERPRINT”

Tropical Rainforest No seasons…consistently warm Wet and Wetter times of year 100% moisture surplus

Tropical Savanna and Grasslands Dry and Wet Seasons Moisture Deficit, evaporation>precipitation for ¾ of the year (October-June)

DESERT Moisture Deficit, evaporation>precipitation year round Precipitation less than 2cm per month

Temperate Grassland Moisture Surplus Year Round, – Precipitation>evaporation 4 distinct seasons

DECIDUOUS Moisture Surplus Year Round 4 distinct seasons Consistent precip year round Precip> than temperate grasslands supports larger and a greater # of producers

TEMPERATE RAINFOREST Moisture surplus 11/12 months Not as steep a distinction in seasons Precip> 2x temperate deciduous

BOREAL FOREST (TAIGA) Moisture surplus year round 4 distinct seasons Above freezing 1/3 of the year 1/8 the precip of temperate rainforest, 1/3 of the deciduous

TUNDRA Moisture surplus year round due to very low temps (above freezing 1/6 of the year) Precip only slightly > than desert Support for only low-lying vegetation Permafrost

Photosynthesis of the Planet What carries out photosynthesis in the ocean?

ZONES OF THE OCEAN LITTORAL BENTHIC: the deep oceanthe deep ocean TIDAL ZONES: CORAL

WETLANDS CONDITIONS nutrient availability (nitrates and phosphates for example) suspended matter that affects light penetration depth temperature currents bottom characteristics currents connections(aquatic and terrestrial)

Types of Wetlands Bogs (fed by precipitation) and Fens (fed by groundwater) Swamps(forested) and Marshes(tidal) Lakes(littoral and benthic)

Lakes Zones Littoral: Light reaches the bottom (swamps and marshes are entirely littoral) Epilimnion: still photosynthetic (limnetic) Thermocline: layer where light will stop (“warm to cold”) Hypolimnion (profundal): No sunlight Benthic (benthos): organisms feed on detritus
