Question

Accepted Answer

Hello everyone. And in today's video we have the following problem. We have that the carrying capacity of a forest for a deer population is not affected by which of the following. So remember the word we're not we're looking for or answer choice. That is incorrect or does not apply to the carrying capacity of this forest. And so before we jump into the problem, let us recall what the carrying capacity means for a community and it is the maximum or the number of members in a community that can be tolerated by the ecosystem. So if this if there's way too many members in that community and it exceeds the carrying capacity then the ecosystem will be disrupted which can bring negative consequences. Now this is the carrying capacity. There is many factors that affect us such as food, shelter, water and the availability of mates for that specific species. So all of these factors will be affecting us. So let's go over answer choices so that we can identify which one does not apply to the carrying capacity. Starting with food. Well the more food that is available for a particular community, the more members that will be able to join this community. So it will increase the carrying capacity. We can cancel this out and the same applies to water. The more water that is available, the more number, the number of species and the more members in that community will be will be able to join it. And so we're going to cancel that as well as it will increase the carrying capacity, then we have answer choice c which is predators. If we have a high enough number of predators, these predators are going to keep the number of species that very city and members in the species very low, so the carrying capacity will be lowered for that community. So predators will also affect the carrying capacity of a deer population since they're actively preying on these deer. And then finally we have wildlife photography, which is really not, it does really not have anything to do with carrying capacity or affecting the number of members that the community will be able to tolerate without disrupting the ecosystem. So we're going to highlight wildlife photography, answer choice D as being or final answer. So, thank you very much for seeing around until the end of this video. I really hope it helped you.
