Although protist flagella have a diversity of forms and functions, [11] two large families, flagellates and ciliates, can be distinguished by the shape and beating pattern of their flagella. [ 2 ] In the phylogenetic tree on the right, aquatic organisms (living in marine, brackish, or freshwater environments) have their branches drawn in blue ...
Primary nutritional groups are groups of organisms, divided in relation to the nutrition mode according to the sources of energy and carbon, needed for living, growth and reproduction. The sources of energy can be light or chemical compounds; the sources of carbon can be of organic or inorganic origin.
There are many modes of feeding that animals exhibit, including: Filter feeding: A form of food procurement in which food particles or small organisms are randomly strained from water. Deposit feeding: obtaining nutrients from particles suspended in soil; Fluid feeding: obtaining nutrients by consuming other organisms' fluids
Protistology is a scientific discipline devoted to the study of protists, a highly diverse group of eukaryotic organisms. All eukaryotes apart from animals, plants and fungi are considered protists. [1]
Osmotrophy is a feeding mechanism involving the movement of dissolved organic compounds by osmosis.Organisms that use osmotrophy are called osmotrophs.Osmotrophy is used by diverse groups of organisms. [1]
Heterotrophic Protists. In the microbial food web, protists including ciliates and flagellates are significant consumers. By consuming bacteria, algae, and other tiny particles, they move nutrients and energy up the food chain. Larger creatures like zooplankton feed on these protists in turn. [3]
Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It provides organisms with nutrients , which can be metabolized to create energy and chemical structures.
Holozoic nutrition (Greek: holo-whole ; zoikos-of animals) is a type of heterotrophic nutrition that is characterized by the internalization and internal processing of liquids or solid food particles. [1]
