It is called a response. Organisms react to their surroundings in order to survive and thrive in their environment.
It would depend on which animal. If it has a brain, it can "feel" in one way or another. Animals with no brain like coral cannot feel, but they do react to negative stimuli as all living things do.
Trees do not have sensory organs like animals do, but they can still respond to their surroundings through mechanisms such as phototropism (growing towards light), gravitropism (sensing gravity to grow roots downwards), and thigmotropism (responding to touch by growing around obstacles). Additionally, trees can communicate with each other and other organisms through chemical signals released into the air or soil.
