Question

giant pandas were once extensively scattered in eastern and southern china, as well as in certain areas in neighboring countries, such as burma and vietnam. today, this herb
animal species is on its way to extinction. human activities are the major causes for the constant decline in the population of the giant panda.
which activity is least likely contributing to the decrease in the giant panda population?
bioaccumulation
habitat destruction
migration obstruction
poaching

Explanation:

• Habitat destruction (e.g., deforestation for agriculture, urbanization) directly reduces the living space of giant pandas.
• Migration obstruction (e.g., building roads, dams) disrupts their movement for food, mates, etc.
• Poaching for their fur or body parts also harms the population.
• Bioaccumulation (accumulation of toxins in the body) is less relevant as a major direct cause compared to the others for giant pandas.

Answer:

bioaccumulation
