Explanation:
The cellular communication is an important aspect of unicellular and multicellular organisms in the environment. The cellular communication may differ in the bacteria, plants and animals but the mechanism of cellular communication remains the same.
The mechanism involves the receptors, change in the structure of receptors which triggers the signal to respond and then the response of the cell. Therefore the evolutionary biologists must look at this mechanism and the molecules associated with this mechanism.
The biologist can look at these receptors and the ligands which initiate the transduction process in the organisms.
That they were probably on land and that they evolved into sea animals or that that mountain used to be an ocean or water source and that it dried up and a mountain grew there. I'm not positive that this is correct though.
Explanation:
First of all let's see, what's an <em><u>ecosystem</u></em><em>?</em>
- the ecosystem is defined as the result of what happens when a community of living organisms shares and interacts within their environment.
What this means is that the ecosystem is a product of a <em>specific community</em>. There are several types of ecosystems, for example, a marine ecosystem, the rain forest ecosystem etc.
Now, what's a <em><u>community</u>?</em>
- A community in itself is a group of beings that share something in common and work, interact, and live together.
What happens with the community is that the definition of it does not extend to the specifics of which types of ecosystems can come out of the myriad of communities that exist.
Conclusion: Therefore, a community is a formed group of beings with common locality and with a capacity to come together under a common denominator to establish as specific mode of existence, namely, an ecosystem.
I hope this was helpful ! :)
