Water Ecosystems
| Question | Answer |
|---|---|
| What is the area where the ocean and land meet and interact? | Shoreline |
| What is an area where the tide and churning waves provide a constant supply of oxygen and nutrients to living organisms? | Intertidal Zone |
| What is a pool of sea water found along a rocky shoreline? | Tide Pool |
| What is the repeated rise and fall in the level of the ocean | Tide |
| What is the area beyond the breaking waves that extends to waters that are about 180 meters deep? | Near-Shore Zone |
| What is the area that includes most deep ocean waters; most organisms live near the surface? | Open Ocean Zone |
| What is the place where a fresh water river empties into the ocean? | Estuary |
| What are the three types of water-based ecosystems? | Saltwater, Freshwater and Brackish-Water |
| What are two types of saltwater ecosystems? | Oceans and Seas |
| How deep can sunlight reach underwater? | 200 m (650 ft) |
| What type of adaptation would an organism need to survive in deep water? | It would need to be able to survive with less oxygen and less sunlight. |
| Name 3 organisms that can live in the intertidal zone. | Crabs, Clams, Starfish, Sea Urchins, Seaweed |
| Can producers live in the near-shore zone and open ocean zone? | Yes, but only near the surface as far as sunlight reaches. |
| What are microscopic algae that live near the surface of the open ocean zone and are the first part of an ocean food chain? | Phytoplankton |
| What are microscopic herbivores that eat algae, making them the primary consumers in the open-ocean zone? | Zooplankton |
| Name the three ocean zones. | Intertidal Zone, Near-Shore Zone and Open Ocean Zone |
| List 6 types of fresh water ecosystems. | Streams, Rivers, Ponds, Lakes, Some Marshes and Swamps |
| List 3 types of plants that live in freshwater. | Cattails, Duckweed and Waterlilies |
| List 3 types of animals that live in fresh water. | Frogs, Turtles, Water Striders, Bass, Catfish, Trout |
| What 2 factors determine the kinds of organisms that live in a fresh water ecosystem? | The temperature and spped of the water |
| What is a mixture of saltwater and fresh water called? | Brackish-water |
| What are the most productive ecosystems on Earth? | Estuaries |
| What adaptations do organisms in estuaries need to have? | Adaptations that allow them to survive in both saltwater and fresh water |
| What are 4 factors that make estuaries ideal habitats for many plants and animals? | 1. Calm and still water, 2. Shallow water, 3. Sunlight easily reaches the bottom, and 4. large amounts of nutrients |
| What are two reasons estuaries are so important? | 1. Prevent Shoreline Erosion and 2. Prevent Coastal Flooding |
