A zone where no sunlight penetrates. Which zone of an aquatic ecosystem tends to have more life, both producers and consumers? The photic zone.
Which aquatic ecosystem has more life?
The coastal zone makes up only 10% of the oceanic environment, but it contains 90% of all marine species. Coastal zones are the most nutrient-rich life zones of the oceans. Coastal zones can be divided up into several different life zones. One life zone that can be found in a coastal zone is an estuary.
What are the zones of aquatic ecosystems?
The zones discussed are the Littoral Zone, Limnetic Zone, Profundal Zone, Euphotic Zone, and Benthic Zone. The Littoral Zone is the shore area of the lake or pond. The littoral zone consists of the area from the dry land sloping to the open water and can be very narrow or very wide.
Which aquatic ecosystem is the most productive and has the most diverse life?
Seagrasses form dense underwater meadows which are among the most productive ecosystems in the world. They provide habitats and food for a diversity of marine life comparable to coral reefs.
Which best describes the aphotic zone?
Which of the following describes the aphotic zone in an aquatic ecosystem? The zone where no sunlight penetrates and photosynthesis cannot occur.
Which zone of an aquatic ecosystem has more life both producers and consumers?
What ocean zone begins at the edge of the continental shelf and then extends outward into deeper water? Which zone of an aquatic ecosystem tends to have more life–both producers and consumers? freshwater wetlands.
Which zone of an aquatic ecosystem tends to have more life — both producers and consumer?
Which zone of an aquatic ecosystem tends to have more life, both producers and consumers? The photic zone.
What are the 3 zones of an ocean?
There are three main ocean zones based on distance from shore. They are the intertidal zone , neritic zone , and oceanic zone . Distance from shore and depth of water define ocean zones.
What are the 4 aquatic ecosystems?
Wetlands, rivers, lakes, and coastal estuaries are all aquatic ecosystems—critical elements of Earth’s dynamic processes and essential to human economies and health. Wetlands connect land and water, serving as natural filters, reducing pollution, controlling floods, and acting as nurseries for many aquatic species.
How many aquatic ecosystems are there?
Aquatic ecosystems are generally divided into two types –the marine ecosystem and the freshwater ecosystem. The largest water ecosystem is the marine ecosystem, covering over 70 percent of the earth’s surface. Oceans, estuaries, coral reefs and coastal ecosystems are the various kinds of marine ecosystems.
What regions of the ocean have the highest biodiversity?
Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than 25% of all marine life.
Is there more life on land or in the ocean?
Scientists now estimate that 80 percent of Earth’s species live on land, 15 percent in the ocean, and the remaining 5 percent in freshwater.
Which ecological zone in the ocean has the vast majority of all biodiversity?
The vast majority (more than 93%) of species inhabit the shallow, nearshore littoral zone, and 72% are completely restricted to the littoral zone, even though littoral habitats are a small fraction of total lake areas.
