Click on the flashcard to see the answer
What is Freshwater Biology?
The study of living organisms in freshwater ecosystems.
What are some examples of freshwater ecosystems?
Lakes, rivers, ponds, and wetlands.
What is the importance of freshwater ecosystems?
They provide habitats for a wide variety of plants and animals and are a source of drinking water for humans.
What are the major threats to freshwater ecosystems?
Pollution, habitat destruction, invasive species, and climate change.
What adaptations do freshwater organisms have to survive?
Gills for breathing underwater, streamlined bodies for swimming, and camouflaging colors.
What is eutrophication?
The excessive growth of algae and aquatic plants due to high levels of nutrients in water.
What are some examples of freshwater organisms?
Fish, amphibians, crustaceans, mollusks, and aquatic plants.
What is the difference between a lake and a pond?
Lakes are larger and deeper than ponds.
What is the water cycle?
The continuous movement of water on, above, and below the surface of the Earth.
What is bioaccumulation?
The build-up of pollutants in the tissues of organisms as they consume contaminated food or water.
What is the role of decomposers in freshwater ecosystems?
Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.
What is the difference between a river and a stream?
Rivers are larger and flow more forcefully than streams.
What are some examples of invasive species in freshwater ecosystems?
Zebra mussels, water hyacinth, and snakehead fish.
What is the pH range of most freshwater ecosystems?
6.5-8.5 (slightly acidic to slightly alkaline)
What is the primary source of energy in freshwater ecosystems?
Sunlight
