One reason why it is challenging to explain the effects of eliminating a keystone species on biodiversity is that these effects can be indirect and indirect. make this like a 6thgrader wrote it
It's super hard to explain what happens when we remove a keystone species from an ecosystem, because the effects can be kinda tricky and sneaky. Sometimes, things happen that we don't expect and we're like, "Whoa, how did that even go down?" These effects can be direct, like when something happens right away, or they can be indirect, like when something happens over time. So, it's tough to give a simple explanation, because there's a bunch of crazy stuff going on behind the scenes!
