What environmental change is most likely to increase the stability of an ecosystem? Answers A) An invasive plant species is introduced to a garden. B) A corn field is allowed to lay fallow (unplanted). C) A section of woods is cleared to make way for sport fields. D) An exterminator sprays chemicals to get rid of pests.

I would say B

Explanation:

Everything else looks like it would decrease the stability

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
