The Effect of Stimuli on the Behaviour of an Organism. Animals and plants react to stimuli (sing. stimulus) which may come from other living things or from the environment. A stimulus usually causes the organism which receives it to respond to it.Therefore the stimulus changes the behaviour of the organism in some way.he Effect of Stimuli on the Behaviour of an Organism.

Copper is soft and easily bent and so is a good conductor of electricity, which makes it useful for wiring. Copper is also a good conductor of heat and it does not react with water. This makes it useful for plumbing, and making pipes and tanks.
The opposite is not true. There are lot of good non-metallic conductors. Semiconductors may be very good conductors, there are conducting polymers (not as good as copper or aluminum but properly produced they should conduct better than some metals), graphene is a good conductor.
