As an important habitat within the marine environment, Seagrass meadows a home to several species of fish, turtles, sharks, marine mammals (dugongs and manatees), mollusks (octopus, squid, cuttlefish, snails, bi
are organisms belonging to the kingdomAnimaliaand the phylum Arthropoda. They are a very diverse group of animals that includes but is far from limited to insects, crustaceans, spiders, scorpions, and centipedes. Arthropods make up the largest phylum in the world, with more numbers and species ...
are one of the most diverse ecosystems on earth. As such, they are referred to as therainforests of the sea. Most of them are found at shallow depths in tropical waters. Some of the species that inhabit the reefs are mollusks, worms, crustaceans, echinoderms, sponges, tunicates, and fish...
Phylum Annelida is a wide phylum that is found in marine or terrestrial habitats. Annelids are also called segmented worms, are bilaterally symmetrical, triploblastic, coelomate and, true segmentation. They show organ differentiation and the body is surrounded by a thick cuticle....
* Given that trilobites were largely marine animals, their diet may have largely consisted of dead or decaying matter as well as marine plankton and some crustaceans.Subphylum ChelicerataSubphylum Chelicerata is composed of such marine and terrestrial animals as scorpions, horseshoe crabs, ticks, ...
However, the largest mix of marine producers (and their consumers) exist in warmer ocean waters. Fish and invertebrates are ectotherms that must rely on the temperature of their environment to maintain a constant body temperature. Organisms that exist in frigid waters, such as near the North and...
Crustaceans, such as shrimp, lobsters, and crabs, are another type of invertebrate. Many people enjoy eating these animals. Marine invertebrates, apart from the groups mentioned earlier, are some of the simplest invertebrates and include sponges and jellyfish. ...
the dominant invertebrates are bivalve mollusks and crustaceans. As for the dominant vertebrates, fish dominated the aquatic habitats. Major predators include elasmobranchs in the seas and Xenacanthida in freshwater. Arthropods on land continued to evolve. Some of them grew intogiants. For example, ...
Different natural products can be used to create edible packaging, but the most effective and widely used is chitosan, a sugar made from the chitin shells of crustaceans. This makes chitosan one of the most plentiful biopolymers – and edible packaging a much greener altern...
Producers include green plants in terrestrial and aquatic ecosystems and green algae in deep-sea ecosystems. The photosynthetic algae in a marine ecosystem are also termed phytoplankton. Both green plants and algae produce organic matter through the process of photosynthesis. In some bacteria in the ...
