antelope are huntes by both crocodiles and lions. when antelope bend down to drink water, they are vulnurable to lions on land and crocodiles in the water. The lions hide in the grass and ambush them, while the crocodiles hide in the water and ambush them. which environmental change would cause the crocodiles to lose the competition for food?

The environmental change that would cause crocodiles to lose the competition for food with lions would be the drying up of the water sources. If the water sources where antelopes drink become limited or completely dry up, crocodiles would not have access to their hunting grounds, making them unable to ambush the antelopes effectively. This would give lions an advantage as they can still hide in the grass and ambush the vulnerable antelopes on land.
