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.

Are cockroaches refusing poison baits because of one particular ingredient?
Ainat [17]

it’s somehow re-jiggered its taste system so that the attractant that humans used to draw the insect to poison bait—the sugar glucose—now tastes bitter to the roach, and they avoid it. cockroaches began appearing that avoided the baits, and did so not because they were averse to the poison, but because they were averse to the attractant, glucose. This new trait turned out to be heritable, that is, it had a genetic basis.

Blizzard [7]
Glycolysis is the breakdown of metabolic materials into energy and pyruvic acid. it is supported by me because without energy we wouldn't be able to do anything and almost every thing we do requires energy from taking a walk down to the pumping of blood by the heart throughout the body

What does this animation mean when it says that ATP is like a rechargeable battery?
Solnce55 [7]

I dont know what animation you mean about but i will give my opinion.

ATP are used for energy, they are made inside mitochondria. Mitochondria use oxygen and food to make ATP, which is maybe what u mean by rechargable is because whenever you eat, the mitochondria will produce energy again and again.
