"The natural extinction rate" defines the background extinction
Explanation:
The background extinction rate which is being used for the evaluation of the rate by which the extinction in the earth's geological as well as the biological past took place before the contribution of the human beings as the primary contributors to the extinctions. Extinction happens when the last species of the plants or the animals dies out. This occurs as a result of the climate change or human activity.Background extinction occurs at a steady rate over geological time and is the result of normal evolutionary processes, with only a limited number of species in an ecosystem being affected at any one time.
An reaction that releases energy into the environment.
The enthalpy change (energy taken in for bond breaking of reactants - energy released for bond forming of products) can be used to determine whether a reaction is exothermic or endothermic. Since an exothermic reaction has a negative enthalpy change, it means it releases more energy than what it takes in. Hence the third statement is correct.
