An increase in resource availability typically results in population growth, as more resources mean that organisms have access to the necessary food, water, and habitat they need to thrive. This enhanced availability leads to higher reproductive rates, allowing the population to grow—often exponentially—if conditions remain favorable.

Following this phase of rapid growth, it is common to observe cyclical patterns in population dynamics. A population cycle reflects the fluctuations in population size that occur due to changes in resource availability, predation pressures, disease, and other environmental factors. Such cycles can lead to periods of growth followed by declines as resources become limited or other factors exert pressure on the population.

For instance, if the population grows rapidly due to plentiful resources, it may eventually reach a point where the resources become strained, leading to a decline. Yet, after a time when the environment rebounds (perhaps through recovery of resource levels), the population may rise again, establishing a cycle of population fluctuations.

The other options do not adequately describe the natural responses following an increase in resource availability. Population crashes typically occur due to sudden resource depletion rather than initially following resource growth. Population stabilization implies a leveling off without significant cyclical changes, and population decline outright indicates a decrease without the intermediate growth phase being considered.
