MANGROVE TREES – Adaptations for life in salt water and mud with low oxygen Red Mangrove Has stilt like Roots Black Mangrove – roots below water. “snorkel like root structures called Pneumatophores”
Why Mangrove Ecosystem Important? Mangrove Trees Large Entangled Roots…. 1. Provide habitats for juvenile fish and invertebrates 2. Hold soil well, protects shoreline from erosion from currents, waves, and storms
Coral Reef – Coastal Ecosystems Contintental Shelf Vast assortment of life, stony formation built from seafloor up, sunny, warm waters, colorful
Coral Reef – Abiotic Factors Sunlight Shallow water – moderate movement to prevent sediment from accomulating on polyps Warm Rocks Shells
Arctic – Abiotic Factors Cold, Icy Water – often dominated by ice Ice and snow – reduces sunlight in water Much sunlight in summer, Little sunlight in winter Ocean surrounded by land - bordered by shallow continental shelves of NA, Greenland, Russia, Eurasia
Antarctic – Abiotic Factors Cold Water – often dominated by ice Ice and snow – In winter…water at edges freeze adding an area the size of North America to the continent More Extreme Climate than Arctic Antarctica is a continent….not a frozen sea…it has its own continental shelf
