You may speak to one type of nature.

Aquatic animals Land animals

Sea animals

trees

other plants

fungi

algae, molds, protozoans

rocks, minerals and soil

You may ask an organism/material of that type of nature any question that it would "know". Of course, their response is limited, for instance, a rock can tell you what a robber looked like as it doesn't have eyes. Likewise, don't expect a rat to give a lecture on Quantum Physics.

If you want you can restrict your communication skills to a single family such as Canidae (dogs) this does not work for the family Hominidae (man).
