Ant Forest Magic Ocean’s popular science Q&A question has been updated today. The question is: Who secretes calcium carbonate skeletons to form stony coral? The source code of the correct answer has been sorted out by the editor of Nethuajiang. You only need to look at the following to understand it briefly, and then you can complete the answer and claim the reward.
Answer: coral polyps
Knowledge expansion: Corals can be roughly divided into two parts: the coral tissue covering the skeleton and the calcium carbonate skeleton supporting the tissue. Intuitively, the entire morphological structure of the coral symbiont comes from coral polyps. Every stony coral that can form a coral reef is formed by the accumulation of calcium carbonate skeletons secreted by coral polyps over many years.
