Strangler figs are plants that attach themselves to trees for their growth and support. They absorb nutrition from the host tree and cause it to struggle to obtain sunlight and nutrients. This indicates that Strangler figs is a parasite to the trees.
Orchids are also plants that attach themselves to tropical trees. However, orchids don’t harm the host. Orchids obtain sunlight and moisture from their surroundings. This indicates that orchids are in a commensalist relationship with the trees.
Both Strangler figs and orchids exhibit symbiotic relationship of two different kinds, namely, parasitism and commensalism.
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>
