Answer:

Option B

Explanation:

The answer is option B or "secondary succession occurs." Secondary succession is when an ecosystem is destroyed but because of some key factors such as surviving animals, soil, and other natural resources, those resources then bring the ecosystem back to life. Common ways secondary succession occurs is when you clear out land from trees, and wildlife. The soil of that land is still there, which means that soil will start the growth of grass, and new animals will come back to eat that grass, that land will slowly start to become an ecosystem again.

Answer: Discriminative stimulus

Explanation:

A discriminative stimulus is associated with reinforcement or punishment, that exerts control over a particular form of behavior. The subject discriminates between closely related stimuli and elicits a specific behavior only in the presence of that stimulus. T<u>his stimulus increases the probability of a given response</u> because of their historical correlation with the availability of reinforcement for the response.

In this example, the hungry rat gets food if it presses a bar only when the light is on. The rat learns that is most likely to request this food in the future in the presence of this light, because historically, the request has been reinforced in the presence of this light. <u>The light in the example became a discriminative stimulus and it evokes the response.</u>
