Animal behavior researchers often refer to an activity associated with punishment or reward as an operant. The basis for training animals is the operant conditioning. It is a learning process where the animal would learn base from its behavior as it responds to its environment. In this type of learning, the behavior is either increased or decreased by the results that follows the action. It uses rewards and punishments in order to associate with the behavior. For instance, you are trying to teach your dog to fetch an object, if he succeeds in fetching the object, then you give your dog a treat. The dog would think that what it is doing is good and that it would get a reward from it so it would start learning the behavior.
Answer:
The correct option is <em>'Using parasites for biological control of pests to increase crop yields.'</em>
Explanation:
Using The method of biological control for killing pests is better than using a chemical control. Chemical controls such as pesticides can lead to the pests developing resistant genes against the pesticides. As a result, the pesticides will no longer be useful for killing pests. Hence, killing of pest through biological controls is a better method. For example, the usage of parasites for killing a certain kind of pest. This will increase the crop yield.
Answer:
A species that is not native to a particular region is called an <u>invasive species. </u>
Explanation:
In ecology, invasive species can be described as species which are introduced into an environment. These species are not native to the environment.
Introduction of invasive species in an environment can destroy a stable ecosystem. The invasive species will compete for resources like food, shelter, water etc. They might cause the extinction of the species on which they start feeding. They might fight with predators feeding on the same prey.
