4) biological preparedness
Explanation:
Biological preparedness is a phenomenon that humans and animals have developed over time as a survival mechanism. It explains the tendency of humans and animals to form associations between dangers and some stimuli. In this case, humans tend to associate snakes with danger than flowers to danger. This tendency of humans to associate snakes with danger has made humans, according to evolutionary perspective, to fear and avoid snakes. And so, became a trait for adaptation for humans’ survival.

When the rocks are removed from a desert's ecosystem, the animals that depend on those rocks for homes would be in trouble. If these animals died due to predators and a lack of homes, then the other animals (predators) that depend on them for food would start to need other sources of food. This would cut into another predator's food supply and so on.
