Differentiate Kineses and taxes
A kinesis can be defined as a behaviour in which an organism or a cell changes its random movement speed in response to environmental stimulus. This response to stimulus is non-directional and it enables an organism to hurriedly escape a strange environment. Kinesis occur either when an organism changes the rate of turning or when it changes speed of movement. As the organism speeds up its movement, it may reach a more favorable environment, at that point the rate of movement reduces. For example, when the pullbugs move from a dry area to a damp area it slows down its speed when it blunders into a damp environment. Turning rapidly by an organism similarly is likely to take an organism to a different condition, possibly conducive environment (Fraenkel, G.S.  Gunn, D.L. 1961).

A taxis on the other hand is a natural behavioral response by an organism to a directional stimulus. In this case, the organism has motility and express direct movement towards or from the stimulus. For example, the graylag butterfly has positive taxis to bright light when being followed by a predator. This response help in blinding the predator and hence, enabling the moth to escape (Fraenkel, G.S.  Gunn, D.L. 1961). Similarly, fish are negatively geotaxis, that is, they move their dorsal body surface away from the force of gravity. Taxes are controlled by simple neural mechanisms and are often observed in simple animal and protests (Morris, G.K., et al. 1978).

In conclusion as discussed in this paper, an organism responds to stimuli from their a biotic environment by kineses or taxes movement. This depends on whether the movement is random or directed.
