The habitat of manatees in a Central Florida river would largely depend on environmental parameters that directly affect their survival and well-being. The best response choice would be:
water temperature, water turbidity, water depth, and food sources
This option considers the critical factors that affect manatees, such as their need for warm water, clear water to navigate and find food, appropriate depths for movement, and the availability of food sources like aquatic plants. Other options either include irrelevant factors (like the amount of wind or natural enemies, which don't directly relate to habitat parameters) or are incomplete.
