What is a stinging needle plants interaction with animals?

Question

I need help with a project.

Answer 1

I'm also not exactly sure which plant you're referring to. In general, empirical evidence has shown that intense herbivory can select for thorns, spines, etc. on certain plants.

If you're referring to stinging nettle, their stinging trichomes will deter many animals. However, their young leaves are nutritious and nettles are browsed upon by snails, certain mammals, and insects. Interestingly, it has been shown that herbivore and mechanical damage will cause stinging nettle plants to increase their trichome density (as an example of (i) phenotypic plasticity and (ii) an induced defence). I include the link to the Abstract of the article below.

Answer 2

If you mean stinging nettle, deer in my area love to eat it. They must have tough tongues!
