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.
It could be a yes or no... to me because you try something you did try an put your work in to it when it was hard work.... I agree because you always try when you do something... if it can't be proven at least you tried on it
The answer is: It keeps you Hydrated
Organs,
because a group of organs that function together make up an organ system
Answer:
I choose the ecosystem Wetland. They include trees such as swamp mahogany, swamp paperbark and swamp she-oak. Animals in this area include, Beavers, Muskrat's, and Crane's.
Some adaptations that help the Tree's deal with low oxygen and changing water levels are elongated stems, shallow roots, aerenchyma and adventitious roots.
Beavers have several adaptations that help them in the water, aiding in survival. They have clear eyelids, which protect their eyes and help them see underwater. Valves in a beaver's nostrils and ears can close, keeping water out.
Muskrats have long been recognized by scientists for their role in maintaining wetland ecosystems. By grazing on cattails and other emergent grasses and rushes they help to open the surface of a marsh, keeping it from becoming choked with vegetation.
The whooping crane has many adaptations for its marshy, water filled habitat. The neck of the whooping crane is very long so it can get food from the bottom of a lake, stream, or other body of water without getting its body feathers wet.
