In order to know what species would be affected by change one needs to know the type of change you are referencing.
The population of animals in a prairie community would be negatively affected if one is over hunted because it would change the populations of the other species. This makes the ecosystem unbalanced.
bears
If there was no change in species over time, then all fossils of that species would be identical.
Species can change is there is a mass extinction or if the type of species changed the type of climate or terrain which would would make the species evolve to its new environment so that it can survive.
the thickness of the crust
There are 1,500 species sea stars...so eliminating them would decrease the number of species by 1,500. Any species that rely on sea stars for food will be adversely affected as well.
Currently, the monarch butterfly is experiencing some habitat loss and may be affected by climate change. However, they are not evaluated by the endangered species list. I would say it's unlikely they will go extinct at all, since they could be raised in captivity.
Angiosperms cover a wide group. You would have to look at the individual species.
What would make you think that a mouse is suddenly going to change species if it goes outside? No... Rats and mice are both rodents, but completely different species. One can not turn into the other. Rats would kill a mouse if given the chance.
living things in the biosphere
It would depend completely on the types of species in question. Some possible effects could be: 1) Mutualism --> both benefit from one other. 2) Predation --> one species benefits while the other suffers. 3) Neutralism --> despite interaction, there is no overall affect on either species. 4) Competition --> both species are negatively affected by the other. 5) Commensalism --> one species benefits while the other is unaffected. 6) Amensalism --> one species is negatively affected and the other is not affected.
It would be hotter than it currently is.
