Question

In which zone would you expect to find the greatest abundance of marine organisms?

Answer 1

I believe the correct answer from the choices listed above is the third option. It is in the high littoral zone that you would expect to find the greatest abundance of marine organisms. Organisms are also more complex and often larger in size than those found in the high tide and splash zones.

Hope this answers the question. Have a nice day.

Answer 2

Answer:

Option C, High littoral zone

Explanation:

The ocean zone that is known as the marine ecological realm is the Littoral zone. In this zone effects of tides, long shore currents and breaking waves can be experienced up to a depth of 33 feet.

This zone consists of following features which makes it the most habitable zone of ocean –  

a) Large amount of dissolved oxygen

b) Extensive availability of nutrients

c) Sunlight  

d) High wave energies

e) water motion

f) varying geological nature of shorelines

g) varying nearshore bottoms geology

Due to the above mentioned feature, Lottoral has enormous number of species along with all major phylum type.  

The different types of habitat found in this region are  

a) Coral reefs,

b) sandy beaches,

c) rocky coasts,  and  

d) sheltered embayments  

Hence, option C is correct
