What is a major source of food and oxygen for animal life in lakes and pounds?
They get food by the plants and animals living under the water and they get oxygen by the oxygen dissolved in the water
How do aquatic animals get oxygen and survive?
some have gills (fish and sharks have something simmilar) which suck in water and then seperate the oxygen out of the water. Some water animals like the dolphin and the whale have to swim to the surface to breathe. this is what a hales blowhole is for. Some animals can hold their breath under water for up to 3 days!
How does oxygen get into water for fish to breathe?
Oxygen partially dissolves in water. Respiratory systems of aquatic animals are adapted to get this dissolved oxygen. They have gills for respiration.
Why are there no animals in outerspace?
There is no oxygen. Animals need oxygen to breathe. Plus, no food or water.
How do animals live underwater?
All animals that live underwater must obtain oxygen in one way or another. Fish for example have gills that move water past their blood vessels allowing oxygen to diffuse into their bloodstream. Mammals and some other animals must return to the surface of the water to breath in oxygen. While they are under water they eat many things, other animals, algae, and detritus.
Is oxygen insoluble in water?
Oxygen is soluble in water (dissolves in water). This is the basis for marine animals who breathe through gills and similar structures to get their oxygen.
What is the importance of solubility of gases to aquatic animals?
Aquatic animals still breathe oxygen, even if in water. If there's little oxygen dissolved in the water, they will suffocate.
How does oxygen get to animals at the depths of the oceans?
Oxygen dissolves in water - one of the components of a fishtank is one that bubbles oxygen into the water to keep it oxygenated, but it happens naturally too via different processes. It is this oxygen that fish breathe. Only the top 'layer' of the ocean is particularly oxygen rich, below this, it is colder and poor in oxygen. However water from the top level can become cold and salty under some circumstances, the increased density makes it sink. This is how oxygenated water is brought downwards for bottom-dwelling animals.
Do groundhogs need oxygen under ground to survive?
All animals need Oxygen to respire.
Importance of dissolved oxygen in water?
oxygen is dissolved in water and is also important for the survival of aquactic animals and plants
What animals breathe oxygen?
Every animal breathes oxygen, even fish (they obtain it by the oxygen in the water).
Can a clam breathe under water?
Yes. All aquatic animals have respiratory organs of one sort or another - usually gills - to absorb dissolved oxygen from the water.
