What kinds of organisms does the sublittoral zone usually contains

Different types of oysters, star fish, sea urchins, coral, crabs, and anemones live in the sublittoral zone. They are provided with sunlight and food, but there are also many predators.

Hope that helps!

Explanation:

Typical animals include sea anemones and corals on rocky shores, and shrimps, crabs, and flounders on sandy shores. The zone may alternatively be called the subtidal zone.

Explanation: hope this help and I also hope that you have a SUPER FANTASTIC DAY

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

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.
