What happens when two solutions separated by a selectively permeable membrane reach osmotic equilibrium? what happens when two s
liubo4ka [24]
The answer should be water molecules still move between two solution, but no net movement.
Osmotic equilibrium means where two solution has reached the same amount of water potential because of the osmosis before, they have the same solute concentration now.
Always remember that water molecules still move in all solutions, but just that since there's no more concentration difference, the water molecules that move from right to left and left to right is equal. Therefore there's no net movement.

How does an ecosystem differ from a community
Ray Of Light [21]

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 ! :)
