I think the correct answer from the choices listed above is option B. You can find methanogens in the human intestines. These organisms can  work with or without oxygen. Too much of oxygen for them is toxic. They are obligate anaerobes.

Answer:

Melody is a rhythmic sequence of pitches that create a musical phrase or motif. A melody also consists of two parts: pitch and rhythm. We sometimes think of melodies as the vocal part of a song. However, a melody can also be the top line of your instrumental drop, a signature bass line, or even a unique vocal sample.

Scientists calculated the net primary productivity at two different forest sites. Both forests have the same gross primary produ
Katen [24]

Answer:

The answer is C.

Explanation:

Net Primary Productivity is a term that is used to express the difference between CO2 that is taken in by the plant with photosynthesis minus CO2 that the plant releases.

The two forest sites given in the example may not have the same biodiversity and the same species of plants so we can't be sure of option B.

Again for the same reasons, we can't be sure of option D because we do not know the specific plant species in each forest since they are in different areas.

Option A can be ruled out for the same reasons, the lack of information about the forest sites, since we do not know the death rate of the plants in either of the forests.

Option C can be true because forest A has a higher net primary productivity rate which can be an indication of lower respiratory activity hence lower CO2 production, resulting in the given higher net primary productivity.

I hope this answer helps.
