Question

question 1 - 18
invasive python populations have had a significant impact on biodiversity in the everglades. as a result, there has been a severe decline in the number and variety of mid - sized mammals.
what can be inferred about the relationship between the python and mammals in the everglades? (sc.912.l.17.6)
the python does not prey on mid - size mammals but competes for food and nesting spots.
the python and the mid - sized mammals in the everglades have a commensal relationship but compete for food.
the python preys on mid - sized mammals in the everglades and also competes with mid - sized mammals for food.
the python and mid - sized mammals in the everglades prey equally on each others populations and have formed a mutual relationship

Explanation:

• Option 1: If python doesn't prey on mid - size mammals but competes for food and nesting spots, it doesn't explain the "severe decline in the number and variety of mid - sized mammals" as stated in the problem.
• Option 2: Commensal relationship means one benefits and the other is neither helped nor harmed. But the problem mentions a decline in mid - sized mammals, so a commensal relationship is not likely.
• Option 3: If python preys on mid - sized mammals (which would cause a decline in their numbers) and also competes with them for food (which can further stress their population), this aligns with the situation described (a decline in mid - sized mammals due to python populations).
• Option 4: Mutual relationship means both species benefit. But the problem shows a negative impact (decline) on mid - sized mammals, so this option is incorrect.

Answer:

C. The python preys on mid - sized mammals in the Everglades and also competes with mid - sized mammals for food.
