Phytoplankton stay near the surface of the ocean because they need sunshine for photosynthesis. Deeper in the ocean the light is much dimmer.
PHYTOPLANKTON ARE PLANTS. THEY NEED SUNLIGHT, WHICH IS NON EXISTANT AT THE OCEAN'S DEPTHS.
Very simply. They float around in the sunlight zone, using photosynthesis to produce food. Phytoplankton must stay in this zone to make use of the sunlight.
They stay consistant
Oceans are seawater throughout, not only on the surface.
Dolphins are mammals. They breathe AIR. They do not live in the ocean floor- they swim in water, and come to the surface to breathe. If they were in the ocean floor they would drown.
They prefer to stay near the bottom of the ocean
Glass squids stay between the surface and midwater depths of open oceans.
A seal must stay near the water
it stay at the surface
Sharks get sun from the sun. Some that stay in the deep ocean don't need sun, and others get it by merely swimming near the surface. Basking sharks have a habit of basking in the sun, which is how they got their name.
well, you better know how to swim fast and skip things around you! aligators like to stay near the surface and on the ocean floor! so dont swim there or your dead! lol. but really! why would you want to swim a river with alligators???? well, you better know how to swim fast and skip things around you! aligators like to stay near the surface and on the ocean floor! so dont swim there or your dead! lol. but really! why would you want to swim a river with alligators????
As water warms, it expands. Having expanded, it is lighter, and floats at the surface- where it may be warmed more by the sunlight.
This is because they need Oxygen for respiration
Tiger sharks tend to stay in the deeper waters of the ocean. Usually they stay at around 1,000 feet below the surface.
Tiger sharks do. they sometyimes come to the surface for a while then go back into deeper areas and stay there.
The weather in the ocean is different at certain depth's. At the very bottom, it is burning hot. The top of the ocean is as cold as it could get. Most sea animals like/have to live near a heat source, so they stay at the bottom.
Skates and rays are found near the ocean floor. They are eaten by mostly humans, other animals try to stay away.
Walleye's tend to stay near the bottom of a lake or river during the day. They stay 15-30 feet below the surface when the sun is out due to sensitive eyes. You can find them close to the surface at night, when it's easier for them to see and sought out prey.
Tropical waters are nutrient poor at the surface. When living things die at the surface they sink to the bottom where they decompose. The nutrients that are released when they decompose stay at the bottom because there's a thermocline--the deep water is cold and the surface water is warm and they don't mix. So the surface waters don't have much algae and stay clearer.
In an ocean.
for as long as they can they live in the ocean .
It is impossible to swim in the ocean and stay dry.
She would be destroyed if raised. She's much to brittle to be taken to the surface. A common philosophy is "Save the artifacts, leave the wreck".
