Assuming a 10% trophic efficiency, the herbivore (primary consumer) will get 10% of the producer energy. Then, the second consumer that eat the herbivore will get 10% of the primary consumer energy, so it is 10%*10%= 1% of the primary producers.
Then, the t<span>ertiary consumer should get 0.1% of the primary producers' energy.</span>

Since only 10 percent of energy obtained in one trophic level is successfully passed to the next trophic level in the case of the tertiary consumer ( the organism that is in the third trophic level) the organism will obtain only 1 percent of the initial energy.
For example, a plant would obtain the energy from the radiation of the sun, 10% of that will be passed to a field mouse that eats the plant, and the 10% of the 10% or 1% of the initial energy would be obtained by the hawk.

Brums [2.3K]

There are options for this question they are:

a) neutral stimulus; conditioned stimulus

b) conditioned stimulus; neutral stimulus

c) unconditioned stimulus; conditioned stimulus

d) neutral stimulus; unconditioned stimulus

e) unconditioned stimulus; neutral stimulus

The correct answers are - In this example, the buzzer begins as the neutral stimulus and eventually becomes the conditioned stimulus. The buzzer initially is a neutral stimulus because it have no role to play in the blinking response. Eventually though through learned association the buzzer becomes a conditioned stimulus because you now associate it with a puff of air to the eye which in turn causes you to blink.
