Answer:
The correct answer is 'B'. Due to cutting of pine trees, the squirrels will loose their nesting and food sources.
Step-by-step explanation:
According to the diagram, both rabbit and squirrel are dependent on the pine trees for their habitat and food.
A food web is the connection of multiple food chains with each other.
If more and more pine trees will be cut, the squirrels will loose their home and the predators will start eating them. Eventually their population will decrease.
Now, fox also feeds on both squirrel and rabbit. If the population of squirrel decreases, this will cause a decrease in the population of fox also as they will have less food to eat and may move to another place or worse die.
