While some organisms classified under Kingdom Monera are heterotrophic, other organisms are autotrophic. Meanwhile, fungi are basically heterotrophic, since they consume dead organic matter. Desmids are characterized by extensive variation in cell shape and are found worldwide, usually in acid bogs or lakes. They share the characteristics of both plants and animals. Desmid Planktonic, or on vegetation, mostly in neutral to acidic waters. The euglena nucleus and mitochondria can reproduce independently of the chloroplast. The vast majority of bacteria are heterotrophs, i.e., they do not synthesise their own food but depend on other organisms or on dead organic matter for food. Question: What is a desmid's method of locomotion? Since an algae is a plantlike-protists, which are autotrophs, then desmids are also autotrophs. Are Desmids autotrophic?

Taza Ticket Online Travel Agency, Book Online Your Next Flight & Hotel Answer: Certain insectivorous plants, like bladderwort and venus fly trap, are partially heterotrophic. While in heterotrophic nutrition, food is obtained directly or indirectly from autotrophs. Examples of heterotrophic protists include amoebas, paramecia, sporozoans, water molds, and slime molds. Unicellular or multicellular, eukaryotic, autotrophic or heterotrophic organisms. Desmids are found in abundance in peat bogs. Most are found in freshwater lakes, ponds, and pools, though some inhabit brackish environments.The genus was initially described in the early 1830s by German scientist Christian Gottfried Ehrenberg, making it one of the first known groups of .
