Some plants need sun and obviously nutrients and also if there is no sunlight such as the bottom of the ocean then they just need nutrients and energy
The ocean animals need oxygen to survive.
they can if the ocean is fresh water
There are no plants in the deep ocean, since plants need to photosynthesize to survive. There are plants in shallow water since sunlight is easily accessible.
tropical plants need sunlight, CO2 and water to survive
it depends. however most plants will need at least some light to survive
They all do ... but you may be thinking of plants - they don't need animals to survive but animals need plants.
it depends, but i think that they would eat only plants.
Yes, Animals and Plants need the right climate to survive. c: ~Mystery
Plants need the sun's energy to complete the process of photosynthesis. Plants cannot survive without energy, actually all organisms need energy to survive.
The ocean ecosystem will fall apart. Meat eaters need plant eaters to survive. No meat eaters will cause epidemic. The ocean ecosystem would affect land ecosystem
They posses adaptation feature to the marine habitat.
Green plants can survive with sunlight,water,carbon dioxide and chlorophyll.
