They have different lethal temperatures, dissolved oxygen requirements, and spawning needs that are based on their activity levels and behaviors. The three major zones of a lake described as follows (Fig. Because of the water's movement, rivers and streams tend to contain more oxygen than their lentic relatives and have host species that are adapted to the moving water.Aquatic ecosystems consist of interacting organisms that use each other and the water they reside in or near for nutrients and shelter.
This mode of feeding requires the least amount of motion, allowing these species to conserve energy. a. intensity of wind b. angle of incoming sunlight c. length of daylight d. amount of precipitation b. angle of incoming sunlight Which of these species would you classify as a profundal zone organism? Rising water temperatures and increasing acidification of water linked to increases in carbon dioxide are the greatest threats coral reefs face.

D- Crayfish Imagine you are listening to a series of student presentations in which the speakers hypothesize about the kinds of marine life they would expect to find in an abyssal marine zone.

Light penetrates the uppermost of these, the littoral, which contains floating and rooted plants. They also sampled populations of two species of clam worm, Nereis occidentalis and Neanthes succinea, at each point. The ocean ecosystem is divided into four distinct zones. - 11065741 a. ponderosa pine b. choke cherry c. aspen d. lichen.
Only members of the same species can breed to produce viable offspring.
Estuaries occur where saltwater from the ocean and freshwater flowing from rivers or streams meet, creating a unique habitat oriented around water that has a varied salt concentration and has high levels of nutrients resulting from sediments being deposited by rivers or streams.Wetlands are freshwater ecosystems characterized by the presence of water, which could be several feet deep or simply saturate the soil, often with seasonal fluctuations. Wetlands are very important in regulating water levels, filtering water and improving water quality, reducing flood dangers and providing valuable habitat for plants and animals.Oceans are the largest of the ecosystems, covering more than 70 percent of the Earth's surface.
There are two main sources of oxygen to the photic zone: atmospheric mixing and photosynthesis. a. (a) Littoral zone: The littoral zone adjoins the shore (and is thus the home of rooted plants) and extends down to a point called the light compensation level, or the depth at which the rate of photosynthesis equals the rate of respiration. Other articles where Profundal zone is discussed: lacustrine ecosystem: …and animal plankton; and (3) profundal, the bottom and deepwater area beyond light penetration, supporting dark-adapted organisms. a. frog b. plankton c. crayfish d. floating water plants c. crayfish Which of these species might be classified as a pioneer species? - edu-answer.com
Like oceans, lakes and ponds are divided into four distinct zones: littoral, limnetic, profundal and benthic.

Which part of the cell does this illustration represent? Use these resources to explore the diverse species that exist across the globe, and encourage your students to become good stewards of life on earth.
The limnetic zone is the open and well-lit area of a freestanding body of freshwater, such as a lake or pond.
The littoral zone in an aquatic ecosystem (river, lake, sea) can be defined by the presence of sunlight at the sediment level, and the corresponding growth of partially-submerged to fully-submerged aquatic plants. Ask for details ; Follow Report by Lyndseycrabtree8077 09/19/2017 Log in to add a comment Answer. A detrital feeder in the profundal zone, for example, that finds the oxygen concentration has dropped too low may feed closer to the benthic zone.
a. frog c. crayfish b. plankton d. floating water plants. On local levels, over-harvesting of coral and overfishing threatens reefs, as do invasive species and polluted runoff.Rivers, streams and creeks are classified as lotic ecosystems. A small number of invertebrate taxa are predators in the profundal zone. These ecosystems are characterized by flowing freshwater, which moves to a larger river, lake or ocean, and is present during part or throughout all of the year. Lichens make good pioneer species because they can secrete acid that breaks down rock.
