Question

explain :- 'Living things respond to stimuli'​

Answer 1

Answer:

All living things are able to respond to stimuli in the external environment. For example, living things respond to changes in light, heat, sound, and chemical and mechanical contact. To detect stimuli, organisms have means for receiving information, such as eyes, ears, and taste buds.

To respond effectively to changes in the environment, an organism must coordinate its responses. A system of nerves and a number of chemical regulators called hormones coordinate activities within an organism. The organism responds to the stimuli by means of a number of effectors, such as muscles and glands. Energy is generally used in the process.

Answer 2

Explanation:

Living organisms respond to their environment. Response to stimuli is an important characteristic of life. Anything that causes a living organism to react is called a stimulus(plural is stimuli) Stimuli can be external or internal.

An example of a common tropism in plants is phototropism (or light response). Plants grow towards light sources, and if the direction of light is changed, the plant will also change its direction of growth to accommodate for survive.
