How do tides effect sea life?

Question

Please answer.

I have to write a report.

and I have to do so now. If you are smart and you can tell me please do so. thanks. =]

Answer 1

Tides keep the Oceans Oxygenated therefore maintains marine life.

you might study in an oceanography course. (For example, the Gulf Stream is a current.) These currents are often controlled by winds (the trade winds, for example) or by uneven solar heating of the earth. Currents (and winds) are acted upon by the Coriolis effect. The Coriolis effect is the tendency for currents (or other moving things) in the northern hemisphere to turn to the right, and for currents in the southern hemisphere to turn to the left. This is due to the Earth's rotation, and its influence on currents was first noted in 1835 by Gaspar de Coriolis.

Surface water currents in the world's oceans tend to form large circular patterns or gyres. In the northern hemisphere, these gyres rotate clockwise (turning to the right), and in the southern hemisphere they rotate counterclockwise (turning to the left). In fact, the aforementioned Gulf Stream, flowing northeastward along the east coast of the US, is part of one of these gyres.

So far, we have mainly discussed surface currents, but there are other currents in the oceans, acting at great depths. For instance, cold waters flowing from the Antarctic region are dense (because they are so cold), and they sink to the ocean floor and flow northward. (Note that cold water can hold more oxygen than warmer water, so bottom waters in the world's oceans tend to be oxygenated (but as it moves away from Antarctica, it gradually becomes depleted in oxygen).

Answer 2

The greatest effect of tides on marine life is seen in the intertidal zone - this is the area of the seabed which is exposed at low tide. Animals living in this zone (like mussels, clams, barnacles, worms, crabs, tunicates... the list is huge) are underwater for part of the day but exposed to the air for part of the day as well, so they have to cope with changes in temperature, humidity, desiccation (drying out), predation by animals (such as birds) that can't reach them when they are under water.

Animals trapped in rockpools, even though they are still under water, are affected too. The pool can heat up, and evaporation of the water will increase the salinity of the pool.

Seaweed in the intertidal also has to deal with being exposed for part of the day - they no longer get support from the water to hold them upright, they can't exchange chemicals as efficiently, they risk desiccation.

Hope this helps! Good luck with the report ;)

Answer 3

on the sting of the sea - referred to as the intertidal zone - tides impact marine existence because of the fact tides are a style if kinetic power. Tides (and waves) deliver water and nutrition to animals that stay interior the intertidal zone, and tides get rid of wastes. The organisms merely sit down there and the sea does the paintings. outdoors the intertidal zone, tides have much less effect, different than of direction they convey currents and reason mixing.

Answer 4

well the moon controls the tides which helps with the food chain. as each tide comes in it takes back out plankton which feeds the smaller fish which feeds the bigger fish etc.
