What would happen if animals become extinct?
If animals went extinct there would be less Carbon Dioxide to support photosynthesis and more complex plants would have a difficult time adapting to the reduced levels of Carbon Dioxide. Plants that survived the extinction of animals would be much simpler than presently complex plants.
When a specific behavior is followed by negative reinforcement the behavior is then likely to?
According to the law of effect, behaviors that are followed by consequences that are satisfying to the organism are more likely to be repeated, and behaviors that are followed by unpleasant consequences are less likely to be repeated (Thorndike, 1911).
What is unique about the Sixth Extinction?
The sixth, which is ongoing, is referred to as the Anthropocene extinction. The five mass extinctions that took place in the last 450 million years have led to the destruction of 70-95 per cent of the species of plants, animals and microorganisms that existed earlier.
Why did reptiles survive the Permian extinction?
Terrestrial reptiles (and amphibians) appear to have survived the Permian extinction in large numbers because they were much less affected by the ecological shifts, namely the increased concentration of atmospheric carbon dioxide and the acidification of the oceans.
What birds went extinct because of cats?
They have been implicated in the extinction of several species and local extinctions, such as the hutias from the Caribbean, the Guadalupe storm petrel from the Pacific coast of Mexico, and Lyall’s wren.

What will you do to help in preserving the environment to help prevent species extinction?
Visit a national wildlife refuge, park or other open space . These protected lands provide habitat to many native wildlife, birds, fish and plants. Scientists tell us the best way to protect endangered species is to protect the places where they live.
Is when you take away an unpleasant stimulus to encourage a behavior?
Negative reinforcement is a method that can be used to help teach specific behaviors. With negative reinforcement, something uncomfortable or otherwise unpleasant is taken away in response to a stimulus. Over time, the target behavior should increase with the expectation that the unpleasant thing will be taken away.
What animals may soon become extinct Why might they become extinct?
Species may become extinct because of changes in climate (i.e. the ice age), competition with other species, a reduced food supply, or combinations of all of these. Most natural extinctions are isolated events that happen over a fairly long period of time.
