Answer:
Positive and negative feedback differs in that positive feedback loops increase the initial signal, while negative feedback loops decrease the original signal (option d).
Explanation:
Feedback is a process that, applied to biological systems, allows for the changes needed to maintain homeostasis.
- Negative feedback loop occurs when a stimulus is presented, producing a change in the body, so the response is to stop the change that is occurring. It is the most frequent type of feedback and has the greatest impact on homeostasis. An example of negative feedback is a decrease in body temperature through sweating.
- Positive feedback loop occurs when the stimulus produces a change and promotes a response that reinforces that change. The classic example of positive feedback is the secretion of oxytocin, promoted by uterine contractions, whose effect is to increase those contractions, allowing labor.
<em>In summary, </em><u><em>positive feedback loop acts by increasing an action or signal in the body, while the negative feedback loop reduces or stops the action or signal that occurs</em></u><em>.</em>

The answer to your question is the first choice or choice A. Bacteria is a decomposer. That would be the only valid choice. If the question didn't say decomposer then all of these choices would be correct, but because it only says decomposers, bacteria would be the correct choice.
Darwinism refers to a theory of biological evolution postulated by the English naturalist Charles Darwin and others, suggesting that all the species of organisms originate and evolve via the natural selection of inherited, small variations, which enhance the tendency of the individual to survive, compete, and reproduce.
Of the given options, individuals gaining experience during the developmental process leading to the evolution of the thought process is not a component of the modern theory of biological evolution.
