Answer: If all the predators in an area were to disappear, a population of scavengers would likely be affected in the following ways:
Increased competition for food: With no predators to consume the carrion and reduce the amount of food available to scavengers, competition among scavengers for food would likely increase. This could lead to a decline in the population of scavengers as individuals struggle to find enough food to survive.
Changes in scavenging behavior: The presence of predators can influence the behavior of scavengers, with many avoiding areas where predators are present. With no predators, scavengers may start to venture into new areas and change their feeding habits, which could lead to increased competition with other species. This could also potentially lead to the increase in the population of scavengers as well.
Explanation: It is worth to note that, depending on the specific ecosystem, this change may also cause a cascade effect that leads to the decrease of other species populations. And also the ecosystem will have an overall change due to the presence/absence of a key species like predators.
