DONT USE GOO_GLE FOR DA ANSWERS

A double diet is where an organism gets nutrition from plants/meat and the sunlight. An advantage is that they can stay energised for a long time without having to eat by just staying in direct sunlight.

Explanation:

1. glaciers are melting

2. more water going into ocean (water's such as fresh waters, etc)

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
