Question

what is your opinion of this statement:
"eventually all ecosystems stop changing"

Answer 1

I disagree. First of all, even late successional ecosystems are considered to be in a state of dynamic equilibrium, such that ecosystems are always changing slightly to maintain an overall stable state--if you took a picture one day, and then the next, things wouldn't look exactly the same. If this isn't enough change to make the statement false, then think about the all ecosystems part of the statement. Sure, some ecosystems, like late successional temperate forests, are hard to disturb naturally. However, think of some small ponds, in which you may observe the bloom of a certain algal species one week, and clear water the next--or temperate lakes, which shift their whole structure based on season. Furthermore, let's think about late successional forests for a minute. Do they really stop changing? Do new species ever invade? Do fires change the forest structure? What about glaciers? Shifts in climate? Human disturbances? If we forget about some end all change--what if a comet hits the Earth, say, then we have to believe that the statement is false. Sure, some ecosystems become more stable than others over time, some change less than others daily, and some are more resistant to shifts at all times--but ecosystems are always changing...

Answer 2

Evolution relies on change and change is natural. The earth will gradually get cooler as the core cools and plants and animals will adapt to that.

Where the danger of ecosystems stopping changing lies is probably in the efforts of conservationists!!! They are so determined to protect habitats and so sure they are right without conducting proper scientific studies in the same way as carried out in medical research and other sciences that they are in reality attempting to do just that. Freeze the ecosystem at this moment in time!!

Answer 3

I think the statement goes to the theory that ecosystems tend to evolve to a state of equilibrium.

Think about it in the context of forest succession theory. A temperate forest begins as thick shrubs, grass, and vines. These are replaced by secondary, smaller trees. Eventually, the forest ends up as tall tress with little understory. It will remain this way until there is some sort of a disturbance. Then it will begin again. When it is at its peak, before the disturbance, it is in equilibrium, and changes very little.

Answer 4

In theory an ecosystem could reach an equilibrium. Barring any outside influence.

However, the "all" in that statement, I feel makes it untrue - it would be impossible to ensure all ecosystems will stop changing. And then there's evolution to consider...

Answer 5

I feel persons can consider unfastened to have the opinion that they desire. They will have to be capable to specific there opinion, and people who concentrate (which will have to be plenty of persons) will have to have an open brain, and might be difference there opinion. Some critiques would possibly not grow to be something, however it doesnt imply there nugatory. Even if no one treasures your opinion, you will have to. Its what makes you who you're.

Answer 6

ecosystems will stay the same as long as their environment stays the same. unfortunately that never happens.
weather patterns, creatures inhabiting the area, etc.
they constantly change because they are forced to.

Answer 7

Nothing ever stops changing.

Answer 8

Only two ways that could happen

The system would have found a perfect, unalterable balance or it has totally failed and become lifeless.

Both seem unlikely

Answer 9

I think the only way it would stop changing is if it died out. I don't know??

Answer 10

this is hard to analyze.
but i think this may be true, if we consider the concept of the universe as not infinite.
