Explanation:
this is because of the presence of single-cell, characteristics such as inability to produce food for themselves
The killing of all the algae in a part of the open ocean leads to scarcity of food in the ecosystem. Due to this, the food web becomes unstable and a lack of biodiversity is seen in it.
A food web may be defined as the interconnection of a number of food chains with each other in order to form a web-like pattern. One organism can hold more than one position. The flow of energy is very difficult to calculate. It is a series of branching chains instead of a straight line.
Algae is a type of producer in the aquatic ecosystem which holds energy for the rest of the organisms in the same habitat. From algae, herbivores consume direct energy which is transferred to carnivores. But when algae are died off, due to lack of food herbivores are eliminated. And as a result of this, carnivores are found to be absent.
Therefore, the killing of all the algae in a part of the open ocean leads to scarcity of food in the ecosystem. Due to this, the food web becomes unstable and a lack of biodiversity is seen in it.

Explanation:
Enzymes. Most enzymes are proteins and therefore their function is specific to their structure. ... The enzyme binds with the appropriate substrate only in the correct alignment and orientation to connect the molecules. The resulting enzyme-substrate complex enables the reaction to occur.
