What is true about marine organisms? The organisms present in an aquatic
food web depend upon salinity instead
of depth levels
The organisms present in an aquatic
food web depend upon land related
biotic factors,
The organisms present in a marine food
web depend upon sunlight to exist in the
deep ocean
The organisms in the ocean depend
upon abiotic factors such as depth, light,
salinity, and geography

the correct answer is b

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
