The hay included as part of the culture medium provided a food source for bacteria. Bacteria are a good food source for some typ
lions [1.4K]

Answer:

  • Protozoans → would not have survived because they have no way to produce their own food → Heterotrophs
  • Algae → would have survived without this food source → Heterotrophs

Explanation:

The protist kingdom is composed of two main groups.  The principal difference between them is that algae can produce their own food, while protozoans need to ingest other organisms or organic molecules to survive.

  • Algaes are autotroph
  • Protozoans are heterotroph

<u>Protozoans</u>:

Microscopic unicellular organisms, eukaryotic and heterotrophs -predators or detritivores-. Most of them are aquatic free-living organisms, but some species are parasites. They feed on<u> bacteria</u>, other organic wastes, and other microscopic organisms. The phagocytosis process is normally used to ingest the food, invaginating their cell membrane.  

<u>Algae</u>:

Eukaryotic micro- or macroscopic organisms. Autotroph and photosynthetic. They might be either unicellular or pluricellular. They use sunlight to synthesize organic matter from water, CO₂, and mineral salts. Unicellular ones can be free-living or associate with others to form colonies. They are part of the phytoplankton and are ingested by heterotrophic organisms. Pluricellular algae do not create real tissues but they compose a tale. The depth at which they inhabit depends on the pigments they produce. All of them inhabit fresh or sea waters.

What is diffusion? Include in your explanation "area of high concentration" and "area of low concentration". Does diffusion occu
Luba_88 [7]

Answer:

Diffusion is the process of small molecules moving from a high concentrated area to a lower concentrated area. For example, in a crowded train station, when a train arrives, people move from the high concentrated area, which is the platform, and move onto the lower concentrated area, which is the trian.

Explanation:

The process of diffusion does not cost any energy, as it happens naturally, and would cost energy to go against it, like trying to go from the train into the platform costs more energy than just going with the crowd into the train. And only small molecules can do this without using energy. Large molecules, like starch, can't do this without using energy.(ATP) hopefully, this helped you, and it would mean a lot to me if you could give me brainliest!
