Which patch of floating plastics is the largest and would therefore have the greatest impact on ocean biodiversity?

It is known as the garbage island and is located in the Pacific.

Explanation:

This garbage island has an approximate size of 1.6 million square kilometers. It is composed of large and microplastic objects. Larger plastic objects kill marine life, trapping fish and other animals, such as turtles. This large accumulation of garbage accumulates due to the confluence of the trade winds from the south with the current of the North Pacific, creating a whirlpool that makes it impossible for the plastic garbage to go towards the coasts.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
