Question

which factors involving the activities of people are a threat to biodiversity?
○ pollution and succession
○ habitat loss and predation
○ poaching and habitat loss
○ succession and poaching

Explanation:

To determine the factors involving human activities threatening biodiversity:

• Pollution and succession: Succession is a natural ecological process (not a human - caused threat), so this is incorrect.
• Habitat loss and predation: Predation is a natural ecological interaction (not a human - caused threat), so this is incorrect.
• Poaching and habitat loss: Poaching (illegal hunting) and habitat loss (due to human activities like deforestation, urbanization) are both human - related activities that threaten biodiversity.
• Succession and poaching: Succession is natural, so this is incorrect.

Answer:

C. poaching and habitat loss (assuming the option identifiers are A, B, C, D in order. If the original options have different identifiers, adjust accordingly. Here, the third option in the list is the correct one which is "poaching and habitat loss")
