The right answer is: Plant growth would decrease.
Decomposers are living beings directly involved in the decomposition of dead organic matter (necromass) or excrement or excreta of living beings. They play a major role, necessary for the recycling of the elements (minerals, trace elements ...) that make up the organic matter, in an inorganic matter which will subsequently be absorbed by the plants (which explains the decrease of the growth of the plants during the absence of decomposers).
It is the order of DNA bases- adenine, guanine, cytosine, and thymine (A,T,C,G)
Since ribosomes produce proteins, and the endoplasmic reticulum transports the proteins that the ribosome makes it is advantageous for a protein secreting sell to have ribosomes on the endoplasmic reticulum so that the proteins can be transported more quickly and efficiently
