This event could've caused herbivorous and carnivorous organisms to become extinct because, as the text says, "the impact threw huge amounts of dust into the atmosphere which spread across Earth's sky, blocking the sunlight." By this, we can come to the conclusion that the impact was so great that it killed all life on Earth at that moment, as, according to the text, "dinosaurs, and many other forms of life in all regions of Earth, became extinct." Since the large object mentioned in the text crashed into the Yucatan Peninsula of Mexico, we can also infer that it probably caused a huge tsunami that wiped out the dinosaurs as well as other forms of life in all regions of Earth.
