Final answer:
Animals displaying kinesis will decrease their movement in favorable environments to stay longer and increase it in unfavorable ones to leave more quickly, whereas taxis involves directed movement towards or away from specific stimuli.
Step-by-step explanation:
Animals that move by kinesis will decrease their movement if they are in a favorable environment and increase their movement if they are in an unfavorable environment. This type of movement is undirected and random, and it's based on the principle that by moving more or less, the organism is more likely to remain in or leave a certain environment, respectively. Orthokinesis is when the speed of the movement changes, while klinokinesis involves changes in the rate of turning.
The woodlouse is an example that exhibits orthokinesis by moving faster in response to uncomfortable high or low temperatures, thereby reducing its time in such conditions. Similarly, bacteria like E. coli use klinokinesis to find more hospitable environments. In contrast, taxis is directed movement towards or away from a stimulus, such as the positive chemotaxis in protozoa moving towards a chemical attractant.
