The greatest difference in the littoral zone between fresh and marine ecosystems
marine ecosystem has no plants due to the level of salt water
In lakes and ponds, the area farther from the shore is called the ____ zone.
limnetic
Water with a salinity that is greater than fresh water but less than salt water is classified as _____.
trees that lose their leaves and stop photosynthesis during part of the year
Deciduous
describes average conditions, including temperature and precipitation, over long periods in a given area
climate
Considered the most productive aquatic zone.
Limnetic (Photic)
Rivers and streams are types of ____ fresh water ecosystems.
Lakes and ponds are types of ____ fresh water ecosystems.
flowing; standing
trees that do not lose their leaves at any time of the year
coniferous
zone where the ocean meets the land, mussels, crabs and barnacles might be found here
intertidal
Over a given amount of time, the rate at which plants and algae convert solar or chemical energy into energy stored in the bonds of organic sugars is called ___(3 words)__.
gross primary production
The zone that has the only heterotrophs.
Profundal zone
uppermost zone of an aquatic ecosystem where there is enough sunlight for photosynthesis to occur
photic
zone in aquatic ecosystems that tends to have the highest temperatures
photic
vertical flow of cold, nutrient-rich water toward the surface
upwelling
criteria that scientists use to classify aquatic ecosystems
salinity, depth, and whether the water is flowing or standing
Why the Profundal zone only has heterotrophs
no sunlight
Differentiate between the area near the source of the river and the area toward the mouth of the river.
area near source is where the water is full of oxygen, clear, cold, swift, and near the mouth, the water is warmer, and has less oxygen
In a lake or pond, which zone would you likely find grasses and lots of invertebrates?
littoral zone
shows average monthly temperature and average monthly precipitation
climatograph
Plants found in the ____ of the tropical rain forest will tend to have large, flat leaves.
understory
Deepest zone
Benthos
Discuss the importance of estuaries.
Where rivers flow into the ocean, mixing fresh water and salt water brackish ecosystems called ____ occur.
estuaries
mild, wet winters and warm, dry summers
location--near ocean such as in California and the Mediterranean
chaparral
What is the importance of kelp forests and coral reefs?
Both use light energy for photosynthesis, protect shorelines from erosion, provide food and shelter for a variety of animals, help support biodiversity.
