In this case, the protozoa will be in category B - animal-like protist.
Animals consume other living organisms to obtain energy. Archaea and bacteria are a high level classification of different kinds of microorganisms that include many different subtypes. So these are not appropriate answers as they are not specific enough. Plant-like protists can photosynthesize which these protozoans cannot. Fungus does have similarities with animals in that it consumes living tissue to survive, however animal-like protist is the best fit for this questions.
Answer:
Yes, but not for a long period of time
Explanation:
-> My answer comes from some quick research I did
"Blue Crabs can last up to 24 hours out of the water as long as they are kept cool and moist." (crabbinghub.com)
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Answer:
Firstly, the partial pressure of nitrogen (78%) is crucial to breathing purposes. Without this pressure, the lungs will burst and animals cannot survive.
Secondly, nitrogen is required for the formation of amino acids (building blocks of proteins) and other organic compounds that are necessary for the survival of living organisms. Principally, in the atmosphere, nitrogen is present in the form of molecular nitrogen (N2). N2 is fixed by nitrogen-fixing bacteria that form nitrates and nitrites. These molecules are then used in biochemical processes to produce proteins (amino acids) and other organic compounds. In the absence of nitrogen, these processes could become seize of limited significantly thus affecting life overall.
Thirdly, nitrogen and its derivatives act as greenhouse gases that maintain the Earth's temperature within a range that supports life. Yes, the increased abundance of nitrous oxides is not good because of acid rain and other issues, however, still, the presence of nitrogen is important for life on this planet.
