Final answer:
In stable environments, the Type I strategy, associated with K-selected species, is common due to predictable resources and the production of fewer, well-cared-for offspring. Type III strategy, with many offspring and little investment, is adapted to unstable environments. Economies with high multipliers can be less stable as they amplify changes more than economies with low multipliers.
Step-by-step explanation:
The strategy that occurs more often in stable environments is known as a Type I strategy. K-selected species, which are typically found in these environments, are characterized by the production of fewer offspring with larger investment in each. For example, humans and elephants are K-selected species that provide extensive parental care, ensuring a higher survival rate for their limited number of offspring. This strategy maximizes the success of each offspring in an environment where resources are predictable and competition is high, making it a more sustainable approach in stable conditions.
On the other hand, Type III strategy is more common in unstable environments where the likelihood of young surviving to adulthood is lower. In these settings, species will produce a large number of offspring with minimal investment in each, increasing the chances that at least some will survive to maturity. This strategy adapts to the unpredictability of resources and higher environmental risks.
Regarding economic stability, an economy with a high multiplier may experience more pronounced fluctuations in response to changes in the economy or government policy. The multiplier effect amplifies initial changes in spending through consequent rounds of income and consumption, potentially leading to greater volatility in economic output. Conversely, an economy with a low multiplier might exhibit more stability as changes in spending will have a smaller impact on the overall economy.
