a. seasons
b. tide cycle
c. evolution
d. population growth
please select the best answer from the choices provided

Explanation:

• Seasons are cyclical and repeat every year, so they are short - term changes.
• Tide cycles occur daily or semi - daily, so they are short - term changes.
• Evolution is a process that occurs over many generations (thousands or millions of years), which is a long - term change to ecosystems as it leads to the development of new species and changes in the relationships between organisms.
• Population growth can be a relatively short - term phenomenon depending on the species and environmental conditions. For example, a population of rabbits may grow rapidly in a favorable season but then decline.

Answer:

C. evolution
