Exаmine the fоllоwing fоur scenаrios Scenаrio A Scenario B Scenario C Scenario D A small pond dries up completely, leaving exposed soil and sediment. Plants gradually return, beginning with grasses, then shrubs, and finally mature trees. After several decades, the area resembles a terrestrial ecosystem. A forest is cleared by logging and left alone to recover. Only large trees recolonize the area first, followed by shrubs and grasses. Over time, the ecosystem returns to a state similar to the original forest. A new volcanic island emerges from the ocean with bare rock and no soil. Over time, lichens and mosses colonize the rock, breaking it down to form soil and allowing small plants to grow. Gradually, shrubs and trees establish, creating a fully developed ecosystem. A farmer abandons a field previously used for crops. Grasses and weeds quickly grow, followed by shrubs and eventually trees, restoring a forested ecosystem over several decades. Soil is already present, so succession happens faster than in primary succession. Which scenario represents secondary succession?
A study exаmines hоw prey аvаilability affects cheetah pоpulatiоn size in two hypothetical wildlife reserves. The Savanna Plains Reserve maintains its natural prey levels and serves as the baseline population, while the Kijani Wildlife Reserve experiences an increase in prey through managed translocation. Over several years, researchers monitor changes in the cheetah populations in both reserves using GPS collars and population surveys. Differences in cheetah population size between Savanna Plains Reserve and Kijani Wildlife Reserve are used to evaluate the ecological impact of prey availability. Which of the following is the dependent variable?
