Answer:
B. The city park contains fewer natural predators of the red squirrel than the nature reserve.
Explanation:
When compared to a nature reserve a city park really doesn't have any predators apart from some cats or birds. There really isn't much that can challenge the squirrel in order for their numbers to go down. There is no threat from food shortages and no threat from being eaten by larger animals that could live there.
B) Primary producers. Autotrophs are organisms that produce their own food through photosynthesis, which are primary producers.

Answer:
Fructose 2,6‑bisphosphate (F26BP) activates phosphofructokinase‑1 (PFK -1) and inhibits fructose 1,6‑bisphosphatase (FBPase)
Explanation:
Fructose 2,6‑bisphosphate (F26BP) is a metabolite that is produced with an increase in glucose, hence increasing the availability of fructose-6-phosphate. With, the increased concentration of F26BP, it increases the affinity of PFK- 1 to fructose-6-phosphate, thereby activating glycolysis which enhances the catabolism of glucose. In contrast, F26BP inhibits the activity of fructose 1,6‑bisphosphatase (FBPase), hence inhibiting gluconeogenesis. Gluconeogenesis (formation of glucose) will not be need since there is the presence of glucose in the system.
In summary, fructose 2,6‑bisphosphate (F26BP) reciprocally controls the enzymatic activity of phosphofructokinase‑1 (PFK -1) and fructose 1,6‑bisphosphatase (FBPase); it inhibits gluconeogenesis by inhibiting the enzyme, FBPase and activates glycolysis by activating the enzyme PFk -1
