faltersainse [42]

Water drains into the sinkhole pollution due to factories

The lake was created as limestone gradually dissolved, causing the sediment layer above it to collapse and creating the lake basin. Low lake levels and slow draining can be caused by bottom leaks, sinkholes, and swallets, long-term dryness, and a lack of recent, strong rainfall events.

<h3>What causes lake Jackson to disappear ?</h3>

Before the lake dried up, those walking along the shore of the sinkhole at Lake Jackson on Thursday would have been in three to four feet of water.

  • Environmentalists refer to the process as a "dry down," and it occurs every ten or twenty years. The likelihood of causes includes dry weather, a lack of rain, and a decreased water table.

  • The lake will typically begin to fill again after the sinkhole plugs itself, sometimes taking years to do so pre sinkhole level

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.
