  1. 5. Describes a mixture of freshwater and saltwater. Brackish water has a higher salt content than freshwater but a lower salt content than seawater.
  2. 10. Any vehicle used for traveling on water, including surfboards, kayaks, boats, and ships.
  3. 11. A type of aquaculture involving farming marine organisms, such as fish, shellfish and seaweed in oceans, coastal areas and estuaries. Species are raised in either natural or controlled conditions for food, materials or other products.
  4. 13. The amount of oxygen present in water, essential for the survival of aquatic life. It enters the water from the air or through photosynthesis by aquatic plants
  5. 14. An electronic device used on a boat to measure the depth of water beneath it. It sends sound waves to the bottom and calculates the distance based on how long it takes for the sound to bounce back.
  6. 15. An area of land along the edge of a river, stream or other body of water. These zones are important for supporting diverse plant and animal life and help protect water quality.
  7. 16. The farming of aquatic animals and plants, especially fish, shellfish and seaweed, in natural or controlled marine or freshwater environments.
  8. 18. How cloudy or murky water is due to particles like dirt, algae, or other materials floating in it. Higher turbidity means the water is less clear.
Down
  1. 1. The variety of living organisms within a particular habitat, ecosystem, biome, or globally.
  2. 2. Involving the living components of the environment.
  3. 3. The accumulation of microorganisms, plants, algae, or small animals on surfaces, such as ships' hulls, pipes or underwater sensors, particularly in aquatic environments.
  4. 4. An electronic device used on a boat to detect and locate fish underwater. It uses sonar technology to send sound waves into the water and displays the results on a screen.
  5. 6. The process of breeding and growing new plants or animals.
  6. 7. A natural system, like forests, oceans, lakes or wetlands, that absorbs and stores carbon dioxide from the atmosphere. This process helps mitigate the effects of climate change.
  7. 8. The equipment used for fishing, such as rods, reels, lines and hooks. It includes all the tools and gear needed to catch fish.
  8. 9. A series of interconnected food chains that outlines feeding relationships in an ecosystem
  9. 12. A system formed by the interaction of biotic organisms with each other and with the abiotic components of the environment in which they live. While an ecosystem may be synonymous with a specific environment, the ‘system’ approach enables a focus on the various components and their interconnected nature.
  10. 14. The patterns of activities that meet the needs of the present generation without compromising the ability of future generations to meet their needs.
  11. 17. The non-living components of the environment.
