Marine regions cover about three-fourths of the Earth's surface and include oceans, coral reefs, and estuaries. Did you know that ocean plants are among the most important plant life on this planet? Coral reefs are some of the most diverse ecosystems in the world. ... One type of marine algae is kelp. Herbivorous fish like the butterfly fish pictured to the left prey on marine algae. Adaptations are many and varied but they are generally grouped into 3 main categories: structural, physiological and behavioural. The marine biome. Here’s an interesting fact about the marine biome: algae in the ocean absorb carbon dioxide and produce most of the world’s oxygen! Coralline red algae (Corallinophycidae, Rhodophyta) are important components of marine ecosystems. 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. Articulated corallines grow mostly in low intertidal and subtidal coastal areas. Varieties include blue-green algae, green algae, red algae, and brown algae. Other ocean plants are seaweeds, sea grasses, and mangroves. 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. Kelp is important because it provides shelter and food for a lot of sea creatures. ... in all zones of the ocean. A variety of organisms that live in marine biomes. Facts- Both claws are the same length but have different features. Facts About the Marine Biome. Marine biome biotic factors include bacteria, fungi, algae, plants, and animals. It covers about 70% of the earth. Marine organisms have adapted to the great diversity of habitats and distinctive environmental conditions in the marine environment. Marine Biome Plants. Reef fish and coral off Eniwetok atoll in the central Pacific. Red coralline algae can be found in most marine habitats. Algae in the ocean absorbs carbon dioxide and provides much of the Earth's oxygen. ... Food-Sn ails Habitat-Soft rock surfaces with places to hide Adaptation- Crushing knobs and hooks on claws for eating snails. Marine algae supply much of the world's oxygen supply and take in a huge amount of atmospheric carbon dioxide. The average depth of the ocean is 12,400 feet. Some species of algae are microscopic, unicellular organisms that grow in groups while other types are much bigger, such as seaweed and giant kelp. The ocean is a salty place that is often cold. LOCATION: The marine biome is the biggest biome in the world! Structural adaptations. Examples of algae include kelp and phytoplankton. The term algae refers to many different types of organisms that may be found in a marine ecosystem. Without this crucial predator-prey balance, the algae would over-grow, which … Crustose corallines have been found in …
