The correct answer is - nitrogen and phosphorus.
The nitrogen and the phosphorus are the two substances that cause most of the eutrophication. It is good for the organisms that live in the water when these two substances are available as they are very important nutrients, but if the optimal amount is surpassed than it can be devastating. When there's high quantities of nitrogen and phosphorus in the water it makes it much more rich in nutrients that it should be. That kind of situation is the best for the algae, which start growing all over the place, quickly covering the water and becoming the dominant life form. As that happens, the organisms that use photosynthesis will die out because the Sun will be blocked, and the algae will also contribute to a big reduction of the oxygen in the water too. The end result being totally destroyed ecosystem that has been overtaken by algae.
One of the best examples would be Archaea
No they have a negative charge Protons have a positive charge... I remember because P in Positive and P in Proton
Answer: 300 grams
If Anna’s doctor recommends getting 60% of her calories from carbohydrates, it means that (2000*.60) or 1200 calories should come from carbohydrates.
<span>If one gram of carbohydrate provides 4 calories of energy, then 1200 calories is equal to (1200/4) or 300 grams of carbohydrates Anna should consume each day.</span>
Answer: Carbon dioxide
Explanation:
The chemolithophs are the prokaryotes which uses inorganic matter in order to make organic materials for the other processes.
These organism get energy by the oxidation of the inorganic compounds. The organism such as human beings breaks down the organic compounds in order to get energy and nutritional building block.
The macro molecule used by the organism is carbon dioxide.
