How do scavengers primarily interact with grains?

Scavengers primarily target already damaged grains because they are drawn to food sources that are easier to access and more likely to have been compromised. Damaged grains may exhibit factors such as mold growth, insect infestation, or physical deterioration, making them more attractive to scavengers looking for a meal.

These organisms, which include various insects and pests, sense the nutrients and possible decay in damaged grains, which enables them to exploit the food source effectively. Fresh grains, while they might eventually become a target, are not the primary focus for scavengers since they are intact and less accessible compared to already compromised grains.

Grains stored in sealed bags would typically be protected from scavengers, as these pests cannot access the contents without a breach in the packaging. Finally, scavengers do not attack all types of grains equally; their preferences lean towards those that show signs of damage or deterioration, providing them an easier and more nutritious meal. This is why the response regarding targeting already damaged grains is the most accurate.
