What are the conditions that promote life in the ocean?
In our oceans, there are a number of environmental conditions that affect the growth, survival and productivity of marine organisms. These include light availability, oxygen levels, water movement, salinity, density and pH.
What are the three main zones of the marine environment?
There are three main ocean zones based on distance from shore. They are the intertidal zone, neritic zone, and oceanic zone. Distance from shore influences how many nutrients are in the water.
Why do most marine animals live near the surface of the ocean?
Most marine organisms live within the sunlit surface waters. Strong sunlight supports photosynthesis by marine algae. All marine algae live near the surface because they need sunlight to survive. Most marine animals also live near the surface because this is where they can find food.
What is the shallowest marine habitat What is the deepest?
From the shallowest to the deepest, biologists divide the pelagic into the epipelagic (less than 200 meters, where there can be photosynthesis), the mesopelagic (200 – 1,000 meters, the “twilight” zone with faint sunlight but no photosynthesis), the bathypelagic (1,000 – 4,000 meters), the abyssopelagic (4,000 – 6,000 …
