DECOMPOSITION & NUTRIENT CYCLING: Insects and their arthropod relatives are responsible for much of the nutrient cycling‚ conditioning and aeration of the soil; e.g. dung beetles‚ flies‚ carrion beetles‚ millipedes‚ cockroaches‚ & termites. 3. FOOD FOR WILDLIFE AND IN MEDICINE: Many different kinds of animals eat insects making them essential parts of the food chain; e.g.: amphibians‚ reptiles‚ birds‚ fish‚ arthropods and other invertebrates‚ mammals (primates including humans).

Chikungunya is a viral disease spread by the bite of infected Aedes Aegypti mosquitoes. It causes fever‚ severe joint pain and rash on the body. Chikungunya virus (CHIKV) is an arbovirus i.e. it is an arthropod borne virus and is a member of the genus Alphavirus‚ in the family Togaviridae. The first outbreak of the disease was seen in the year 1952‚ in the Makonde plateau‚ along the border between Tanzania and Mozambique. The disease occurs predominantly in Africa‚ Asia and the Indian

Skin is the soft outer covering of vertebrates. Other animal coverings such as the arthropod exoskeleton have different developmental origin‚ structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin cutis‚ skin). In mammals‚ the skin is the largest organ of the integumentary system made up of multiple layers

species include names like Pantopoda or Pycnogonids. Usually these species are categorized as Arthropods and the sea spiders are under the class of Pycnogonida. The sizes of the sea spiders range between 1 millimeter to over 90 cm (35 inches)‚ the smaller species of sea spiders are usually found in more shallow waters and are under the traditional classification as chelicerates. These marine arthropods are very similar to traditional spiders‚ they are small in the body with eight legs. Some of the

According to Reece et al. (2015)‚ animals can be described as organisms that are multicellular‚ heterotrophic eukaryotes that have tissues made from embryos. The difference between plants and animals are from their source of nutrients. Plants get their food by making them through a process called photosynthesis‚ which makes plants an autotroph. Animals‚ on the other hand‚ get their food by consuming other organisms and ingesting them‚ which makes them a heterotroph. Besides that‚ there are also variations

Animal Kingdom The animal kingdom is a taxonomic kingdom composed of multicellular‚ eukaryotic organisms. Mostly‚ their body structures become fixed as they develop‚ yet still some organisms in this kingdom have the ability to undergo metamorphosis. The majority of these organisms are motile‚ which means they can move on their own and with spontaneity. All animals are heterotrophic‚ which implies that they depend on other organisms for food. Animals live in places that provide their necessities

TETRANCHUS URTICAE AND THE GREENHOUSE STRAWBERRY PLANT Mites belong to the Chelicerata‚ a branch of arthropods and the second largest group of terrestrial animals. Within the order Acari‚ spider mites belong to the Acariformes with fossils dating from the Lower Devonian period 410 million years ago (Edgecombe‚ G. D.‚ 2010). The two-spotted spider mite‚ Tetranychus urticae‚ is a web-spinning mite. The name refers to their ability to produce silk-like webbing used to create
