Which of the following is a negative effect of algal blooms on the environment?
a. transport of carbon to the bottom of the ocean
b. production of oxygen
c. consumption of water’s oxygen
d. large source of energy

c would be your answer i just took the test

The correct answer is c. consumption of water's oxygen

Excessive growth of algae in the water bodies due to presence of nitrogen or   phosphorus from the nearby is called algae blooms. The overgrowth of algae blocks sunlight for submerged plants. Algae bloom may also release toxins in the ponds, lakes. On the death of algae, water dissolved oxygen gets depleted in their decomposition. Due to lack of oxygen other aquatic life unable to survive.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
