Coral reefs, often hailed as the rainforests of the sea, are some of our planet's most biodiverse and complex ecosystems. These underwater cities, teeming with life, are the architects of the underwater world, shaping the very structure of the ocean floor. But how do these majestic structure...
Diving in the ocean,marine biologist Erika Woolsey has seen how coral reefs (珊瑚礁) are being damaged by climate change.It has made her decide to find a way to share her experience —including those who can't easily explore the ocean.Through her non-profit,The Hydrous,Woolsey is using ...
Before learning how reefs form, it's helpful to define a reef. Acoral reef is made up of animals calledstony corals. The stony corals are made up of tiny, soft colonial organisms called polyps. Polyps look a lot like a sea anemone, as they are related to these animals. They are inver...
Coral reefs form from the skeletons of dead coral that have built up over time. These reefs are created through a symbiotic relationship between the coral and single-celledalgae. As the coral dies, the reef breaks into pieces and compact. Our planet displays astonishing biodiversity. It is brim...
These underwater structures, built by colonies of tiny coral polyps, provide shelter, food, and breeding grounds for a vast array of marine organisms. Coral reefs are essential to maintaining the health of marine ecosystems, offering crucial services such as coastal protection, biodiversity support,...
How are coral reefs being damaged?Coral Reefs:Coral reefs are landforms that are found in the ocean. They are built of the skeletons of corals, which are marine animals. Scientists estimate that there may be between one and nine million different species of living things which live in our ...
D. They are built by fish. 相关知识点: 试题来源: 解析 B。解析:文中提到“Over time, these exoskeletons accumulate and form large structures known as coral reefs.”,即珊瑚的外骨骼随着时间的推移堆积形成珊瑚礁,不是直接长得很大,也不是和海草结合或者由鱼建造的,所以答案是B。
Did you know that coral in the sea will die if peoplecut down (at down) more rainforests? It happens like this. If people___(cut down) more rainforests, theworld's temperature___.(rise)If the temperature of the water___(go up) too, the small animals and plants that live in the...
But what is coral bleaching? Coral bleaching is a phenomenon that occurs when the white skeleton of the corals becomes visible after the microalgae that live inside their translucent tissues are expelled. Even though coral reefs can recover from bleaching events, the ...
How many coral reefs are in the ocean? Coral Reefs: Usually found near the equator, coral reefs are the most biologically diverse and dense marine ecology. As the name suggests, coral reef built by reef-building corals with the help of other organisms like red algae or symbiodinium. Today,...
