Question

Shallow lakes with rich organic products are called
(a) Eutrophic
(b) Oligotrophic
(c) Saprotrophic
(d) Meterotrophic

Answer 1

"eutrophication"-answer

the lakes are said to be eutrophic because by throwing domestic garbage in Lake leads to natural aging to lake (meaning of eutrophic)

Answer 2

Answer:

Shallow lakes with rich organic products are called Eutrophic.

Explanation:

• The amount of physiologically important nutrients—such as phosphorus, nitrogen, and others—dissolved in a water body's fluids determines its trophic (nutritional) condition. Increased levels of these limiting nutrients cause greater plant growth in the body of water, which raises its trophic level. The Carlson's index is the trophic index that is most frequently used. Here, the total mass of biomass present in a body of water is used to characterize its trophic condition.
• Eutrophic lakes are those that have a lot of biological productivity. Due to the rich nutritional composition of such lakes, particularly nitrogen and phosphorus, a plethora of plants can be supported. Due to the high quantities of oxygen that a lot of plants growing in the lake give, eutrophic lakes initially speed up the multiplication and growth of lake fauna. However, when things go too far and the lake becomes overrun with plants or algal blooms, the lake's fauna suffers from the high levels of respiration caused by the live vegetation. Both natural eutrophication and anthropogenic environmental impact are possible causes.
