Answer:
All cells get energy from glucose
Explanation:
The main source of energy for all the metabolic process and function of body organ individually and as one entity is glucose. Thus, there is essential requirement to transport glucose to all the cells within the body. Insulin and glucagon hormone regulates, control and facilitates the transmission and production of glucose. Both these hormones works opposite to each other, hence a proper balance is to be maintained for producing adequate amount of glucose
Nutrients from fertilizers, such as nitrogen and phosphorus, can be harmful to aquatic ecosystems primarily because they promote excessive growth of algae and aquatic plants. Hence option b "The increase in algae population reduces oxygen in the water" is correct.
This excessive growth is known as eutrophication. The process unfolds as follows:
Nutrient Input: Fertilizers with nitrogen and phosphorus are often utilized in residential and agricultural settings. These nutrients may be introduced into surrounding water bodies by runoff from these locations.
Algal Blooms: Nutrients function as fertilisers for algae and aquatic plants, causing algal blooms. Algal blooms are therefore created as a result of the fast growth in the population of algae. These blooms can completely cover the water's surface, turning it green or murky.
Oxygen Depletion: The process of decomposition consumes oxygen when the algae and aquatic plants die and degrade. An higher need for oxygen results from the large amount of organic material from the deceased organisms. As a result, the amount of dissolved oxygen in the water may decrease.
