Question

target georgias aquatic biomes draw a line to match each biome to its description biome types river lake estuary coastline description a. a mix of saltwater and freshwater, often found near marshes a large inland body of still water, often fed by rivers or rain a flowing body of freshwater that moves higher to lower elevation the edge of the land where it meets the ocean or sea water properties sort sort each property into \chemical\ or \physical\ (use c or p) 1. ph 2. p temperature 3. salinity 4. turbidity 5. c dissolved oxygen 1. pick two water properties and explain how they might affect fish or plants in a lake. • property 1: ____ - effect:

Explanation:

1. For the biome - description matching:

• River: A flowing body of freshwater that moves from higher to lower elevation (C).
• Lake: A large inland body of still water, often fed by rivers (B).
• Estuary: A mix of saltwater and freshwater, often found near marshes and fed by rivers or rain (A).
• Coastline: The edge of the land where it meets the ocean or sea (D).

1. For water - property sorting:

• pH is a chemical property (C) as it measures the acidity or basicity of water based on the hydrogen - ion concentration.
• Temperature is a physical property (P) as it measures the degree of hotness or coldness.
• Salinity is a chemical property (C) as it measures the amount of dissolved salts in water.
• Turbidity is a physical property (P) as it measures the cloudiness of water due to suspended particles.
• Dissolved Oxygen is a chemical property (C) as it measures the amount of oxygen gas dissolved in water.

1. For the effect on fish or plants:

• Property 1: Temperature. Effect: Changes in water temperature can affect the metabolic rates of fish. Cold - water fish have lower metabolic rates at lower temperatures, and extreme temperature changes can be lethal. For plants, temperature affects the rate of photosynthesis and growth.
• Property 2: Dissolved Oxygen. Effect: Fish need dissolved oxygen to breathe. Low levels of dissolved oxygen can lead to fish kills. Aquatic plants also require oxygen for respiration at night. Adequate dissolved oxygen is necessary for the survival and growth of both fish and plants in a lake.

Answer:

1. River - C, Lake - B, Estuary - A, Coastline - D
2. 1. C, 2. P, 3. C, 4. P, 5. C
3. Property 1: Temperature, Effect: Affects metabolic rates of fish and photosynthesis/growth of plants. Property 2: Dissolved Oxygen, Effect: Necessary for respiration of fish and plants, low levels can be lethal.
