Higher amounts of nitrogenous compounds will increase algal blooms, leading to less available oxygen in the water, and decrease biodiversity. -------- Let's take a look at each option and consider them in light of our knowledge. 1. These compounds will combine into larger molecules as they interact in the nitrogen cycle and become food for fish and other animals, increasing biodiversity. * This has some problems. Yes, the fertilizers will cause an increase in the food supply, but that doesn't spontaneously cause an increase in biodiversity. The only way to increase the biodiversity is to introduce new organisms. And this isn't such a mechanism. I won't pick this choice. 2. The water cycle will remove excess fertilizer naturally through evaporation, with no impact on biodiversity. * There's some issues here as well. Think about how much fertilizer runoff is considered a pollution issue. If this option were true, then we wouldn't be seeing so many news articles complaining about fertilizer running causing pollution problems. So this answer isn't any good either. 3. Nitrogenous compounds will be recycled into carbon compounds to create new organisms and increase biodiversity. * Still running into the "spontaneous increase in biodiversity" issue here. How would more carbon compounds suddenly increase the biodiversity? This answer isn't any good either. 4. Higher amounts of nitrogenous compounds will increase algal blooms, leading to less available oxygen in the water, and decrease biodiversity. * This is a real problem. Some might think that "Algae is a plant. Plants produce oxygen. Why would more algae cause the oxygen supply to decrease?" Well, the answer is pretty simple. Individual algae cells don't live very long. So you have a log of algae being produced. Releasing oxygen to the air, and then dying. And the dead algae then proceeds to decay, which does consume dissolved oxygen in the water. Which does cause the death of fish and other animals that are dependent upon that dissolved oxygen. And that does reduce the biodiversity in the area. So this is a reasonable and correct answer.

using the food web, describe two complete food chains that include a ptoducer, consumer, and descomposer.​
Damm [24]

Answer:

A food chain is a representation of what eats what in an ecosystem.

A combination of food chains is termed as a food web.

Example of two food chains in a food web are :

Example No 1:

Plant----- Grasshopper------ Frog---snake--- bacteria

Example No 2:

Plant---- rabbits---- fox---- bacteria

In a food chain, producers are usually plants and algae which are able to make their own food. Consumers feed on the plants. In example no 1, grasshoppers are primary consumers, frogs are secondary consumers, snakes are tertiary consumers.

In example no 2,plants are producers, rabbits are primary consumers and foxed are secondary consumers.

Decomposers are organisms that feed on the dead organisms in a food chain. In both the examples of food chain, bacteria are the decomposers.

What is one of the biological uses of Nitrogen? PLZ HELP
Lisa [10]

Nitrogen is a fundamental element required during the growth and development of any organism.

  • Nitrogen is a fundamental chemical element required to synthesize different biomolecules such as nucleic acids (either DNA or RNA) and proteins.

  • Amino acids are the bounding blocks of proteins, whereas nucleotides are the building blocks of nucleic acids, and both contain nitrogen.

  • All organisms in their growth phase requires nitrogen in order to synthesize these biomolecules (i.e., nucleic acids and proteins).

In conclusion, Nitrogen is a fundamental element required during the growth and development of any organism.
