coastal estuary
Euryhaline organisms are more likely to be found in estuaries, as they can tolerate a wide range of salinities. Stenohaline organisms, which can only tolerate narrow salinity ranges, are less common in estuaries because of the fluctuating salinity levels in this environment.
Estuaries would be a likely environment for marine organisms well adapted to drastic changes in salinity, as estuaries experience fluctuations in salinity levels due to the mixing of freshwater from rivers and saltwater from the ocean. Organisms in estuarine environments have developed physiological mechanisms to tolerate these changes.
The answer is plankton..
Millions of years ago, when these rocks formed, it is likely that the environment was very different from the present. It could have been a marine environment with shallow seas, indicating the presence of marine organisms. Alternatively, it could have been a terrestrial environment with rivers, lakes, or forests, suggesting the presence of land-dwelling organisms. The specific characteristics of the rocks can provide further insight into the environmental conditions at that time.
An inability to adapt to its environment would likely be the most common.
The change in sea levels will prevent many organisms from migrating. Marine organisms will be the most likely to adapt.
The likely word is the transposition algae, a plural noun (from alga) for mostly one-celled marine organisms.
That is known as natural selection, a key mechanism in the theory of evolution. Organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to future generations.
maybe, maybe not The world may never know
Small shelled marine organisms are the most common easily observable fossils found in rocks.
Ammonites were marine animals that likely fed on small fish, plankton, and other small marine creatures. The shape of their jaws and radula suggest a diet of soft-bodied organisms.
Stable ocean conditions and temperatures contribute to a more predictable and consistent marine environment. Organisms that rely on specific conditions for survival are likely to thrive in these stable ocean conditions. However, sudden changes in ocean conditions or temperatures can disrupt the balance of marine ecosystems.
