How would the decrease in tree ferns would affect the triceratops?

The decrease in tree ferns, which were a significant food source for triceratops, would have a direct impact on their diet and nutrition. Triceratops relied on tree ferns for sustenance, so a decrease in their availability could lead to malnutrition and potential population decline. This change in food availability could also disrupt the triceratops' ecosystem and lead to cascading effects on other species within their environment.
