Describe a change caused by kenitic energy as well as a change that involves potential energy

A change caused by kinetic energy is if a ball is moving and it bounces and goes down it is energy and gravity acting upon it . when the ball stops then it has potential energy

kinetic energy object in motion

potential energy object at rest

Bacteria

Explanation:

Some plants, specifically leguminous plants form a symbiotic relationship with certain bacteria species called NITROGEN-FIXING BACTERIA in their root nodules. In this relationship, the bacteria species e.g nitrosomonas, nitrobacter etc help the plants fix atmospheric nitrogen (N2) or ammonium compounds, which are forms of nitrogen that are unusable to the plant into nitrates, a usable form.

Therefore, BACTERIA are the organisms found around the roots of these set of plants (legumes) that turns nitrogen from the form we cannot use to the form we can use.
