Document Summary

Distribution of aquatic biomes: aquatic biome distributions impacted by, climate, nutrient and oxygen availability, sunlight availability, primary producers, buoyance important (structural support is not, water is not limiting, distribution of producers governs distribution of consumers. Thermohaline circulation: upwellings, along shore winds move ocean surface water, deeper surface water is moved away from coast, this water is replaced by deeper, cold, nutrient-rich waters from ocean depths. Intertidal zone: rocky, sandy or marty beach exposed to air at low tide but underwater at high tide. Coral reefs: part of neritic system, most diverse oceanic biome (25% of the fish species but only 1% of earth"s surfa(cid:272)e(cid:895, shallow tropical/subtropical reefs. Natural barrier that protects shorelines from storm surges and erosion due to regular wave action: corals and symbiotic zooxanthellae (algae) primary production to support very diverse ecosystem, deep sea reefs build up more slowly (lack zooxanthellae) Pelagic realm: photic zone: photosynthetic algae and cyanobacteria, along with the protists, zooplankton, fish and cephalopods.
