Matter is recycled, but energy must keep flowing into the system. 6 terms. Carnivores (secondary consumers) such as mountain lions hunt and consume the deer.In hydrothermal vents, the food chains producer is autotrophic bacteria. E. red tide. Primary consumers such as snails and mussels consume the autotrophs. Under harsh conditions, plasmodial slime molds produce reproductive stalks called sporangia that contain spores. Fungi live on (the leftovers of) other organisms and are therefore considered to be heterotrophs. An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. hold lots of water. b. multicellularity b. foraminiferans "Protista Kingdom of Life." .

The macronucleus undergoes meiosis to produce haploid micronuclei that are exchanged in conjugation; this then produces a micronucleus for general cell housekeeping. heterotrophs; they are either consumers (slime molds) or decomposers or parasites (water molds) protist. Autotrophs are usually plants; they are also . Heterotrophs depend either directly or indirectly on autotrophs for nutrients and food energy. Other protists, such as algae, exhibit a type of alternation of generations in which they alternate between haploid and diploid stages in their life cycles.

Autotroph, Heterotroph, and Energy Flow Explained a. volvox Promoting heterotrophs. These temporary extensions of the cytoplasm allow the organism to move as well as to capture and engulf organic material through a type of endocytosis known as phagocytosis, or cell eating. Heterotrophs can only obtain their energy from other living, or previously living, sources. E. having a cell wall of cellulose and having diploid adult forms both make water molds different from fungi. This is an amoeba with finger-like pseudopodia (dactylopodia).

Fungi are heterotrophs, meaning they cannot produce their own food. B. synthesis of carbohydrate. Are water molds autotrophs or heterotrophs? - Answers 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! c. diatom Living organisms obtain chemical energy in one of two ways. D) Conclude that your expectation might have been wrong. National Geographic Headquarters 1145 17th Street NW Washington, DC 20036. An autotroph is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) using carbon from simple substances such as carbon dioxide, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis). Radiosynthesis is the process in which fungi obtain energy from radiation. and an additional one-and-a-half million Slime molds & Water molds [edit | edit source] There are two phyla of slime moulds and one phylum of water moulds.

This is apparent from Figure below. Most species are saprotrophic (i.e., they live on dead or decaying organic matter), although some cause diseases in certain fishes, plants, algae, protozoans, and marine invertebrates. This huge blob of cytoplasm with many nuclei resembles slime that moves slowly in an amoeba-like fashion.

STEVE GSCHMEISSNER/SCIENCE PHOTO LIBRARY/Getty Images. Herbivores are the second trophic level. Other protists are heterotrophs, which acquire nutrition through feeding on other organisms. The producers, as autotrophs are also known, begin food chains which feed all life.
