Answer:
Explanation:
There are four ocean zones named as the neritic zone, midnight zone, twilight zone and abyssal zone depending upon the depth of water and the availability of sunlight. Other factors like pressure, oxygen, salinity contributes to the diversity of organisms found and develop in these zones. These factors also makes the organism unique in forms due to living in the oceanic zone.
The two adaptations are as follows:
1. Many organisms which live in the neritic zone are adapted to bouyancy. Some organisms float to conserve the energy for swimming, others float to fatch food near the surface of shallow waters.
2. The animals in the twilight or disphotic zone are adapted to live life in darkness which is found in cold water and high pressure. They have adaptations such ability to see in dark waters and they produce bioluminescence to catch food in darkness.
They all regulate and support your body’s functions. They all work together by stabilizing each detail and movement of your body and keeps it functioning.
