Video transcript

Hello everyone and welcome to today's video. So we need to choose the correct statement regarding habitat corridors. So, I want you to recall from previous videos what this term means and in case you forgot. I want to help you recall it. These habitat corridors are going to be or are going to allow the safe movement between isolated populations and areas. So if a population is called population A is an in an isolated space, it can use these habits are corridors to move to a new area in this area, it might find new resources or just shelter. So they are very beneficial for these isolated species. Knowing this, let's go over answer choices so that we can solve the problem. Beginning by answer choice A. They expand the food supply for many species. Since we saw here these isolated species are going to be able to reach new areas and these new areas may have food shelter and many other resources, which would definitely expand the food supply for these isolated species. This is a correct statement. So we're not going to cancel it out. Then we have B they in increase the likelihood of predation here. Remember that this allows the safe movement between isolated populations and areas. So this is not going to be a true statement because predation is most likely not going to take place in this habitat corridors. Then we have see they contribute to the death of numerous organisms. Remember again that these are safe corridors. These are habitat corridors that allow the movement of isolated populations and areas in a safe manner. So again, this is not going to be a true statement, since the only statement that we were not able to cancel out is going to be statement A That will be the final answer to our question. This habitat corridors definitely expand the food supply for many species. This is the end of the video, and I really hope this helped you.

When wild plant and animal populations are logged, fished, or hunted, only the oldest or largest individuals tend to be taken. Many of the commercially important species are long lived and are slow to begin reproducing. If harvesting is not regulated carefully and exploitation is intense, what impact does harvesting have on a population's age structure? How might harvesting affect the population's life table and growth rate?
