? Biofouling – Definition and Explanations

Introduction

we give a name biological pollution the contamination (a issue (Matter is the substance that makes up any body that has material reality. Its…) solid) immersed in the aquatic environment consists of living things due to organisms or organisms (bacteria, protists, plants and animals). This phenomenon is mainly found in marine environments where zooplankton are relatively diverse and abundant, but to a lesser extent in freshwater environments.

Description

the biological pollution the same area may consist of hundreds of different species. part plankton (Homer, from the Greek plankton, defined the animals that walk on the surface of the waves…)from invertebrate larvae (porifera, cnidarians, bivalves, brachiopods, tunicates, urochordates, tubeworms, etc.), plants and bacteria (Bacteria (Bacteria) are prokaryotic single-celled living organisms, characterized by…) will eventually let’s sit downthat is, anchored on it substrate (down sand (Sand or arena, small…mud, rock) or on a suitable support (other animal (An animal (from Latin animus, spirit or vital principle) according to classical classification, a…) Or else herbal (A group of classical scientific classifications under the term plant…)sitting or not dead (Death is the final state of a biological organism that ceases to live (even…) or alive reef (Rasif, from Arabic rasif (“cave, dyke”)…) artificial due to human constructions… etc.) for:

• Or anchor there permanently (Certain algae and aquatic plants, foraminifera, sponges, corals, some hydroids, tunicates, tube worms, barnacles, barnacles…etc). These are called living things epibionts. Most time (Time, by man…if the epibiont is removed from its substrate and remains intact water (Water is a ubiquitous chemical compound on Earth, essential for everyone…)it no longer attaches to the substrate and eventually dries up at the mercy of predators.

• But stop everything (The whole, understood as the whole of what exists, is often interpreted as the world or…) by being able to move, albeit slowly, either on the substrate or in some cases in open water (bivalves, brachiopods, sea anemones, etc.). If these organisms are removed from the original substrate and remain in full water, if they are reattached to the substrate, they can attach to it and live normally.

• Some animals, plants, and other species do not always wait to release sperm and eggs into the water, which will lead to plankton larvae that will attach to the substrate after fertilization; If this creature is broken for one reason or another, the severed “limb” will drift in the water until it attaches itself and individual (WikiDictionary is a free and open source dictionary project similar to Wikipedia (both…) separate (Or a new colony in the case of colonial animals). such as in some cnidarians coral (Coral is an animal of the phylum Cnidaria, it usually lives in colonies…) to beator certain algae such as caulerpa.
