well at least i think
dont give me wrong
no
overpopulation
abiotic
Loss of one species from a community has a large effect. This is because this can cause major changes in food webs and chains and can cause other organisms to die.
It can cause overpopulation of a species formerly eaten by the oil covered animal, and cause animals that ate it to die due to lack of food.
E. O. Wilson's book "The Creation" explores this concept very well. In short, biodiversity decline refers to rapid extinction of species. It is a threat to mankind because of the intricate interconnectedness of all species. Loss of one species can lead to overpopulation of another dangerous species.
If an area is having overpopulation then it is sure that they will suffer insufficient resources.Therefore,to fulfill their needs they just migrate to some place which is known to have jobs and sufficient resources.Since they migrate to other place the pevious one is free from overpopulation and hence the population is evenly distributed and balanced.
commensalism
Koalas are not endangered, and they have only recently been added to the "threatened species" list in parts of Australia. While they have all but disappeared from some regions in Australia, in other areas there is definitely an overpopulation problem. Kangaroo Island is one of these areas.
There are three possibilities: 1. Both benefit 2. Parasite benefits, host gets harmed 3. No effect: both are neutral
one species wins and the other isn't harmed or helped one species wins and the other isn't harmed or helped
Hunting is a form of "harvesting" of certain species by other species, having a net effect of reducing the impact of one species (those killed) by increasing the impact by others. Others are of the opinion that: Hunting doesn't benefit the environment.
The species that benefits other species are the common carnivores who eat meat
