Today, the farmland is covered in a variety of grasses, shrubs, and small trees, and is home to rabbits, gophers, and other small animals. The evidence most strongly supports which of the following conclusions? A. The farmland is undergoing primary succession, which eventually will restore the original climax community. B. The farmland is undergoing secondary succession, which eventually will restore the original climax community. C. The farmland is undergoing secondary succession, which may or may not restore the original climax community. D. The farmland has undergone primary succession, and is now a stable climax community.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

the answer would be d : p
