Chemical Environment – High in nutrients due to tides Many inverts, some fish, many birds Figure 52.16 (Campbell 9th ed) 44 Aquatic Biomes Marine Coral Reef Physical Environment - Shallow corals: Photic neritic benthic zone w/ warm H2O (18-30oC) - Deep corals: Aphotic oceanic benthic zones 400-2000m Chemical Environment - High [O2] & low freshwater (i.e. not in estuaries) Organisms - Shallow corals symbiotic w/ photosynthetic algae (feed corals) - Many invertebrates and fish due to complex structure Coral polyps w/ CaCO3 skeleton 45 Aquatic Biomes Oceanic Pelagic Zone – Photic Mostly Phytoplankton (1o producers) and zooplankton (1o consumers) w/ some free swimming fish, mammals, squid etc. 46 Aquatic Biomes Oceanic Pelagic Zone - Aphotic Blobfish Anglerfish 48 Terrestrial Biomes A collection of worldwide regions with similar climatic conditions and thus similar vegetation adapted to specific climates Figure 52.9 (Campbell 9th ed) 49 Climate varies with latitude Results in atmospheric and oceanic circulation patterns Due to differential heating of Earth’s surface by the sun 50 Climate also affected by topographical features Temperate rainforest and desserts of the Pacific Northwestern USA Air rises and cools and drops moisture on west side of mountains then dry...
