How the abotic factors affect the inhabitants
temperature determines which zone many animals of the rocky shore live in. The
zone an animal lives in depends on the amount of change it can withstand. Water holds heat much better than air, therefore
orginizims living in the Sublittoral Zone don't have to endure
as many changes as the animals in the Littoral and Midlittoral Zones do. The animals living at in the upper
zones have to tolerate daily swings in these abiotic factors including temperature, which can vary tens
of degrees. The temperature
of the animals' surroundings also affects their rate of metabolism. Very cold conditions will slow it down, whereas
very high temperatures may speed it up.
The sunlight reaches all zones of the rocky shore.
The most sunlight reaches the Littoral Zone. Another reason there are many animals which live in the Sublittoral Zone
is because the light and heat from the sun still reach the bottom, without the dramatic changes that occur both outside and
inside the water everyday. Some examples of thses changes include wind, temperature and tides.
