• Deep sea
• Open ocean
• Intertidal zone
• Coral reefs

Which ecosystem is this? : These ecosystems are the areas of shorelines that are left uncovered during low tide but which are underwater during high tide; they are usually rocky, but in tropical areas they may be sandy; organisms that live here need to adapt to the waves, the sun, and both marine and land predators (a)

Which ecosystem is this? : These ecosystems occur where rivers connect with oceans; the flows of nutrients carried by the rivers make these ecosystems some of the most nutrient-rich and bio-productive areas on Earth; many species live here, and many more will come here each year to breed and raise their young (a)

• Open ocean
• Intertidal zone
• Estuaries
