The Answer is Quick energy.
Answer:
bacteria, archaea, eukaryota
Answer:
Bats are the only mammals that can fly, but vampire bats have an even more interesting distinction—they are the only mammals that feed entirely on blood.
Nocturnal Behavior
These notorious bats sleep during the day in total darkness, suspended upside down from the roofs of caves. They typically gather in colonies of about 100 animals, but sometimes live in groups of 1,000 or more. In one year, a 100-bat colony can drink the blood of 25 cows.
During the darkest part of the night, common vampire bats emerge to hunt. Sleeping cattle and horses are their usual victims, but they have been known to feed on people as well. The bats drink their victim's blood for about 30 minutes. They don't remove enough blood to harm their host, but their bites can cause nasty infections and disease.
Hunting for Blood
Vampire bats strike their victims from the ground. They land near their prey and approach it on all fours. The bats have few teeth because of their liquid diet, but those they have are razor sharp. Each bat has a heat sensor on its nose that points it toward a spot where warm blood is flowing just beneath its victim's skin. After putting the bite on an animal, the vampire bat laps up the flowing blood with its tongue. Its saliva prevents the blood from clotting.
Young vampire bats feed not on blood but on milk. They cling tightly to their mothers, even in flight, and consume nothing but her milk for about three months.
The common vampire bat is found in the tropics of Mexico, Central America, and South America.

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.
