Adaptations in a biome as unique as the Coral Reef,there has to be a way that plants and animals can live there without many issues.Being the biome with one of the highest levels of biodiversity,they have to adapt just as most life has to. Over 90% of the life on Earth lives in the ocean. Coralline red algae (Corallinophycidae, Rhodophyta) are important components of marine ecosystems. Without this crucial predator-prey balance, the algae would over-grow, which … Did you know that ocean plants are among the most important plant life on this planet? Here’s an interesting fact about the marine biome: algae in the ocean absorb carbon dioxide and produce most of the world’s oxygen! A variety of organisms that live in marine biomes. Kelp is important because it provides shelter and food for a lot of sea creatures. ... in all zones of the ocean. Coral polyps, the animals primarily responsible for building reefs, can take many forms: large reef building colonies, graceful flowing fans, and even small, solitary organisms.Thousands of species of corals have been discovered; some live in warm, shallow, tropical seas and others in the cold, dark depths of the ocean. Adaptations are many and varied but they are generally grouped into 3 main categories: structural, physiological and behavioural. Marine biome biotic factors include bacteria, fungi, algae, plants, and animals. Other ocean plants are seaweeds, sea grasses, and mangroves. Crustose corallines have been found in … ...

Varieties include blue-green algae, green algae, red algae, and brown algae. Facts About the Marine Biome. Marine algae supply much of the world's oxygen supply and take in a huge amount of atmospheric carbon dioxide. Examples of algae include kelp and phytoplankton. Marine organisms have adapted to the great diversity of habitats and distinctive environmental conditions in the marine environment.
