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.

The purpose of ethical guidelines for handling of experimental subjects is to ensure the safety and well-being of all living creatures in an experiment.
Ethical guidelines include issues such as human rights, animal welfare, safety compliance with the law, conflicts of interest, health standards..
Ethical guidelines are the norms for the acceptable and unacceptable behaviors of the researchers.
Answer: To ensure the safety and well-being of all living creatures in an experiment
Explanation:
ureters
c.
pancreas
b.
kidneys
d.
urethra
b iis to prevent wind erosion
c is to increase weathering
d is to prevent deposition
The answer is; B
Sometimes winds carry the sand of the beaches causing erosion. The fences act as breakers of this wind erosion. As wind tries to carry the sand, they encounter the fence and 'break'. Therefore, the sand is deposited along the fence forming a sand dune. These dunes also form protection from storm surges.
