According to Selye's theory of stress, during the condition of the stress, the body undergoes the general adaptation syndrome, which occurs in three stages. These three stages are fight or flight, resistance reaction, and exhaustion.
The flight or fight reaction is stimulated by the hypothalamus. It results in the excitement of the sympathetic division of the autonomic nervous system. The resistance reaction is caused by the hormones released by the hypothalamus; this is long lasting and provides ATP (adenosine triphosphate) molecules for the counter reaction to the stress.
As the result of use of ATP and other energy resource from body during the resistance reaction, the body becomes deprived of energy. This causes the exhaustion in the body.
So, the resistance phase of the stress expands a considerable amount of energy, which causes exhaustion.

Answer:
Succession is the natural evolution that occurs in an ecosystem by its own internal dynamics, that is, it refers to two stages of something that is (precisely) successive in time.
Explanation:
Genetic diversity occurs at various levels of the organization of the ecosystem, through the species that compose it, from its subspecific populations (provenances), family groups and individual genotypes, down to the molecular level of the gene. A succession consists of the process of change that an ecosystem undergoes over time, as a consequence of changes that occur both in the conditions of the environment and in the populations that comprise it, giving rise to an increasingly organized and complex ecosystem. The effects of a succession are the change in the structure and dynamics of an ecosystem over time, as a result of an interaction of physical forces that break in from the outside and development processes generated within the system. Also when the classes of ecological changes are controlled by the community, changes will occur in the physical substrate and the microclimate, altering the composition of species and diversity as a result of competition and other interactions of the populations. Species diversity tends to increase with succession, the species undergo mutations or transformations, given that the soil, air and even water (abiotic factors) have also undergone important transformations during the succession.
