There is no presence of photosynthetic pigments, They are heterotrophs in nature, which means they cannot make their own food, and they depend on other organisms for food, The Animalia Kingdom is highly diverse with some organisms being extremely simple in terms of structure and organisation, and some being specialised with a complex tissue organisation structure, These organisms can produce both sexually or asexually, Common examples of the animal kingdom include Chordata- vertebrates like birds, reptiles, fishes, mammals and amphibians, Mollusca- squid and snails, Anthropoda- insects and crustaceans and more. Some are autotroph in light while in dark they behave as heterotroph. Before we explain the definition of autotrophic and heterotrophic, we should provide a little basic background on carbon. They feed on dead or decaying organic matter, hence they depend on saprophytic modes of nutrition, They have cell walls present in them, which is made of a substance called chitin, Fungi can be either unicellular or multicellular; while yeast could be an example of unicellular, mushrooms could be an example of multicellular, They are heterotrophic organisms in nature, Reproduction occurs through both sexual and asexual methods of spore formation, Carbon is stored in fungi, not in the form of starch, but in the form of oxygen, Examples of fungi include Mushroom, Yeast, Aspergillus, They consist of fine threads known as hyphae. (What does it use to move?) By color. For example, Amoeba, Euglena, Paramecium etc. Heterotrohps absorb organic materials down in both living and dead organisms. Archaebacteria It includes halophiles that are found in extreme salty areas; thermoacidophiles. Most of the protists live in water, some in moist soil or even the body of human and plants. The group is an important component of phytoplankton in all but the colder seas and is an important link in the food chain. Desmids have two sections or semi-cells that are joined by a narrow isthmus. Desmids have two sections or semi cells that are joined by a narrow isthmus. When conditions are favorable, a population explosion or bloom may occur, sometimes resulting in contamination of fish and shellfish and posing a threat to human and animal health. Lv 6. Their mode of nutrition is heterotrophic, which means they cannot make their own food and rely on external sources. Slime Molds. of nutrition. This means that they are able to get food two different ways, by eating other organisms and making their own nutrients. Most of these organisms live in either freshwater or water bodies that are motionless. Imagine a teeny, tiny little critter that has two tails, an eye, can make its own food and whose offspring bursts out of it, killing it in the process. The group is an important component of phytoplankton in all but This system was developed by Robert H. Whittaker in 1969 and was based on the work done by previous biologists like Carolus Linnaeus.
