Whta is better for an ecosystem slow changes or fast changes? and why?

I would say slow changes

Explanation:

For example Imagine you're really really freezing cold then you're burning up hot. Your body would not react well to this. You may throw up, pass out, ect. Not in the same way obviously to your question but imagine it for that. Although as the changes are beneficial it should be fine either way

cells spend most of their time in interphase
