Question

If the temperature of our oceans continues to rise, what possible long-term effect will this have on marine organisms?

The geographic range of phytoplankton will be reduced and thus shrink the base of the marine food chain.

The overall temperature of the oceans will increase as will the distribution of marine life.

The salinity of ocean waters will decrease and thus endanger marine life diversity.

The available oxygen of ocean waters will decrease thus reducing marine life diversity.

Answer 1

I go with the first answer, cos

phytoplankton(floating plants in ocean which are found around ocean surface and are fed on by small and large fishes,

but mainly the small) which floats around the sea surface is supplied with nutrients from the ocean depth, and these nutrients only come to it when the surface of the ocean is cold, then the temperature rises,

this nutrients needed for phytoplankton growth is no longer supplied to it.

hence they die, this reduces the food for small fishes causing them to die off and in the process reducingg the food fo larger organisms
