Why is an ecosystem never constant?

Biology

SVEN [57.7K]3 years ago

Lots of factors play different kinds of roles on ecosystems.
Ecosystems are never constant because there are so many levels and layers of animals to each one. It's impossible for the headcount of each species to stay the same within an ecosystem when instances such as flooding, drought, poisoning, and hunting can take part. 
Let's say the hawk, who is over the bunny on the pyramid, gets poisoned by water. Now, there's fewer hawks, which means there's less predators to hunt the bunnies, hence causing more bunnies and even increasing the chance of overpopulation. 
The animals within ecosystems keep each other in check, but numbers are constantly going up and down as things happen. Natural disasters, pollution, and anything such as, effects the ecosystem, therefore it cannot remain constant.

<h3>What is meaning of Extinction?</h3>

Extinction is the final phase of a sort of creature or a taxon—typically a species. Although the ability to reproduce and bounce back may have been lost earlier, the death of the last member of the species is typically considered to be the moment of extinction.

Determining this point is challenging because a species' potential range may be quite wide, and is typically done after the fact. Due to this problem, there are phenomena like Lazarus taxa, in which a species that was thought to be extinct suddenly "reappears" after a period of apparent absence (usually in the fossil record). Estimates place the number of extinct species at over five billion, or more than 99% of all species that have ever existed on Earth.

What are the possible genotypes of the parents of a male child who is colorblind?
viva [34]
Color Blindness is an X-linked trait. This explains why males are much more likely to have it than females. Offspring inherit Color Blindness from their mother, because the father only contributes the Y chromosome.
