Answer:
Ribosomes are macromolecular machines, found within all living cells, that perform biological protein synthesis. Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains.
Explanation:
sponges must get their food by "eating" organic matter in their environment; they do not make their own food like plants.
The correct answer is option B.
This shows commensalistic relationship.
What is commensalism?
Commensalism is a biological relationship (symbiosis) in which individuals of one species profit, while those of the other species suffer neither advantages nor disadvantages.
This is in contrast to parasitism, which is related to parasitism in that the parasitoid has a free-living state and eventually kills its host rather than just damaging it, amensalism, where one is damaged while the other is unaffected, and parasitism, where one is harmed and the other benefits.
The host species, which is largely unharmed, may provide nourishment, shelter, support, or means of mobility for the commensal.

Non-prokaryotic organisms typically have two life cycle stages: trophozoite and cyst is Protozoa.
<h3>What is Protozoa?</h3>
- Protozoa is a group of single celled, non- prokaryotic organisms.
- These may either be free living or parasitic in nature.
- These are heterotrophs and reproduce asexually by binary fission.
- The Protozoa consists of many unrelated or loosely related organisms.
- They are divided into four major groups: Sarcodina, Flagellates, Ciliates and Sporozoans..
- Some protozoa consist of two phases in their life cycle: proliferative stage (trophozoites) and resting stage (cysts).
- Trophozoites consists of the proliferative stage in which the protozoa divides and reproduces.
- The resting cyst form helps the protozoa to survive harsh environmental conditions like harmful chemicals, extreme temperature and nutrient and water deficiency.
