What Type Of Chemicals Can The Free-Living Nematode, Pangrellus Redivius, Sense In Its Environment? Introduction Chemo sensation allows animals to detect food, predators, potential mates, and other key stimuli in their environments. Animals identify chemicals as attractants or repellents and modify their behaviour accordingly. Multi-cellular animals sense chemicals using specialised cells in the nervous system. Free-living Nematodes are sensitive to numerous environmental chemical stimuli, and will chemo tax to an attractive (water soluble or volatile) compound, and avoid noxious compounds. These animals will also modify their movement, egg laying, feeding, defecation, and their developments based on the detected food available. Observations can be made into their actions via the use of a low-powered microscope or by macroscopic visualizations. Results can be recorded in a table format; a conclusion can be made; and evaluated. Nematodes are the most abundant metazoan within soil, and being decomposers are important for the health of...
