is there a food chain that doesn't need sunlight?

Question

I need to find out for my school project and so far i can't find anything and it's due in two weeks so please help me.

Answer 1

Twokay is correct -

Hydrothermal vents at the ocean floor (where it is so deep there is no light at all) - typically along the Mid-Atlantic Rift - produce very hot and sulphorous water, due to the vicinity of magma through the Eath's crust.

Along these vents there are a large number of thermophyllic bacteria species that produce organic molecues and energy from the highly su;phorous conditions. There are also a number of algae strains that utilise the by products these bacteria produce and therefore can survive in these conditions. The algae is used as a foodstuff for a curious species of shrimp that are also adapted to live in these extreme (high temperatures and acid content) conditions.

So you have a bacteria => algae => shrimp food chain independant of sunlight.

Answer 2

There is only one food chain on earth. That food chain cannot exist if there was no sunlight (rays of the sun).

Answer 3

no because in every food chain, we are going to start with a plant and a plant needs sunlight to be able to perform photosynthesis. No sunlight, no plant; no plant no food chain

Answer 4

The chain reaction ouver this predatorical periodisation would be so, even on a microscale organism,human cell could've ensured
should it be replaces of any non-edible or nonpotable liquids either. a twin headed,or even doubler wouldn't had got paid faster electricaly,either, I'd guessed.

Answer 5

There are organisms that live in or near hydrothermal vents on deep sea beds. They do not rely on oxygen or light to survive.
