Which description best explains how blueberry seeds are dispersed?

• A. The blueberries produced by the plant will be eaten by an animal, and the blueberry seeds will be excreted in the animal's droppings at a new location
• B. The plant's blueberries will disintegrate, and the seeds inside will fall to the ground and later stick to the fur of an animal that walks by
• C. The seeds are carried by wind away from the plant
• D. The blueberries will explode and seeds are shot out to distant locations

Answer: (A)

Blueberries are fleshy fruits, and many plants rely on animals to move their seeds to new places. When an animal eats the fruit, the seeds often survive digestion and are excreted in the animal’s droppings at a location away from the parent plant. This endozoochory mechanism is effective because the fruit provides a tasty reward, the seeds are protected during digestion, and the droppings can help germination with nutrients present in the feces. This description fits blueberries well: the fruit is eaten, and the seeds are dispersed via the animal’s droppings rather than relying on seeds being shed on the ground, sticking to fur, blown by wind, or explosively ejected from the fruit. The other dispersal options don’t align with how blueberries typically spread their seeds.
