Ocean ecosystem: Mixotrophic microorganisms play key role Are water molds autotrophs or heterotrophs? - Answers Jones and Bartlett, chapter 33 by Michael W. Dick. Because most autotrophs transform sunlight to make food, we call the process they use photosynthesis. What position do autotrophs fill in a food chain? Heterotrophs cannot make their own food, so they must eat or absorb it. Examples of heterotrophic protists include amoebas, paramecia, sporozoans, water molds, and slime molds. 6 terms.

Sexual reproduction is possible, but typically only occurs during times of stress. a. cysts Some of the rabbits may move to a better habitat, and some may die. Yeasts are single-celled fungi that are commonly used to make bread and beer. PhotoheterotrophsSome varieties of bacteria use light to create their own food, just like organisms that use photosynthesis. AP BIO PROTISTS. This makes fungi heterotrophs, which means they use organic compounds as food to provide energy for growth, development, and reproduction. This page titled 2.18: Autotrophs and Heterotrophs is shared under a CK-12 license and was authored, remixed, and/or curated by CK-12 Foundation via source content that was edited to the style and standards of the LibreTexts platform; a detailed edit history is available upon request. Oomycetes B. Chlorophyta. This process stores energy from sunlight in the chemical bonds of glucose. While photosynthesis transforms light energy to chemical energy, this alternate method of making food transfers chemical energy from inorganic to organic molecules. Instead, fungi must consume the organic matter and energy of other organisms to survive; this makes them a critical part of the recycling process that keeps all forms of life alive on Earth! The macronucleus undergoes meiosis to produce haploid micronuclei that are exchanged in conjugation; this then produces a micronucleus for general cell housekeeping. C. chloroplasts originated when a nucleated cell engulfed a cyanobacterium. C. Volvox. Fungi can even exist in the air because they can be carried long distances in the form of spores. Some are photosynthetic autotrophs, meaning that they are self-feeders and capable of using sunlight to generate carbohydrates for nutrition. Which is NOT part of the correct description of a protozoan? E. ciliates. Some of the most recently discovered chemosynthetic bacteria inhabit deep ocean hot water vents or black smokers. There, they use the energy in gases from the Earths interior to produce food for a variety of unique heterotrophs: giant tube worms, blind shrimp, giant white crabs, and armored snails. This is in contrast to autotrophs like plants or chemosynthetic bacteria that are able to produce their own food from inorganic sources.
