<span>A negative feedback loop works by adjusting an output, such as heart rate, in response to a change in input, such as blood pressure. A basic loop consists of a receptor, a control center and an effector. If you are at rest and your blood pressure increases, pressure receptors in your carotid arteries detect this change in input and send nerve impulses to the medulla of your brain, or control center. This signals the brain to reduce nerve impulses that stimulate your heart muscle, an effector, to contract. Your heart contracts more slowly and your output, or heart rate decreases, causing your blood pressure to decrease to within target levels.</span>
Answer:
Most organisms that live in coral reef habitats are zooxanthellae.
Explanation:
zooxanthellae are the single-celled dinoflagellates that lives in mutual relationship with corals, jellyfish, and nudibranchs. These organisms have a mutualistic relationship between zooxanthellae and corals. Coral produces carbon dioxide and water in the process of cellular respiration while on the other hand, the zooxanthellae use this carbon dioxide and water to carry out photosynthesis for making their own food like plants so both the organisms get benefit from one another.
