What is organic indicator?
Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.

How can a nonnative species effect the ecosystem?
A nonnative species can disrupt the balance of an ecosystem by outcompeting native species for resources, preying on native species, introducing diseases, or altering the physical habitat. This can lead to declines in native species populations, changes in species interactions, and overall ecosystem instability.
What terms defines chance in allele frequency that have a big effect in small populations?
Genetic driftChanges in the frequency of alleles within a population is called genetic drift. Over time, this can cause a significant phenotypic shift from other populations of the same species that have not had the same genetic drift. Given enough time, genetic drift can be significant enough to cause the affected population to be reproductively isolated from the rest of its species and eventually will develop into a new species.

Which of the follwing is an effect of the reduction in bird populations?
The largest effect of a reduction in bird populations is the increase in insect populations. Insect populations grow if there are fewer birds around to eat them.
How do erosions effect animals populations?
They effect animal populations because...... They do! if this ain't the answer you want, well then...... DEAL WITH IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
When a species becomes better adapted to life on land what is the effect on their populations?
When a species becomes better adapted to life on land, their populations may increase due to an expanded habitat range and access to new resources. This adaptation can lead to increased competition with other species and changes in ecosystem dynamics, which can further affect population size and distribution.
An important effect that hunter-gatherer societies may have bad on the environment was?
An important effect that hunter-gatherer societies may have had on the environment was, EXTINCTION.
What effect do keystone species have on an ecosytem?
They maintain biodiversity

Where do many species display founder effects?
Probably the best documented example of the founder effect in action is the Galapagos islands. However the founder effect is seen much more commonly in mountainous regions. Mountains offer many various environmental settings which may cut populations apart. An excellent example of this are populations which cross onto the opposite side of a mountain range than the rest of their species. This is very frequently seen in birds.
What is divergence in relation to evolution?
Divergence in evolution refers to the process by which populations of organisms gradually accumulate differences over time, leading to the formation of new species. It occurs when ancestral populations become isolated or encounter different environmental pressures, causing them to adapt in different ways. Divergence is a key mechanism driving the vast biodiversity seen in the natural world.
