Question
Humans built a large housing development in the forest which is the habitat of the foxes. The foxes now use human trash as a source of food.(2 marks)4
Outline how the population of foxes could be affected by this change.
Outline how the population of foxes could be affected by this change.
▶️Answer/Explanation
Ans: The population of foxes could totally be affected by this change in a few ways. First, with human trash as a food source, more foxes might be born and their population could grow fast. Second, if they rely too much on human trash, their hunting skills might decline and they might struggle to survive without it. Plus, more interaction with humans could lead to conflicts and harm to the fox population. So, it’s a mixed bag of effects on the foxes population.
Question
Describe how the deer population would then be affected.(3 marks)
▶️Answer/Explanation
Ans: With the housing development on their habitat, the deer may have limited access to natural food sources. As a result, they may rely more on human trash for sustenance, which could lead to changes in their diet and potentially impact their overall health and population dynamics. It’s important to consider the long-term effects of such disruptions on wildlife.
