Species Flittera minor Borealis agile Granivora maxima Terranova robusta Traits Short lifespan (1–2 years) High reproductive rate (100+ offspring per season) Little to no parental care Population size fluctuates widely with environment Moderate lifespan (5–7 years) Moderate number of offspring (10–20 per season) Some parental care Population can fluctuate but often stabilizes in favorable conditions Long lifespan (20+ years) Low reproductive rate (1–2 offspring per year) High parental care and investment Stable population near carrying capacity (K) Long lifespan (15 years) Relatively high number of offspring (15–30 per season) Partial parental care Population size moderately stable but can occasionally boom under ideal conditions Which species is most likely K-selected

Examine the following four scenarios Scenario 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 primary succession?

Examine the following graphs. Graph 1 Graph 2 Which of the following is correct?

A study investigates how soil bacteria influence the nitrogen cycle and, in turn, plant growth. Different densities of soil bacteria are added to separate soil samples to test their effect on nitrogen availability. Plants are grown in each soil sample for four weeks, and their growth is measured regularly. By comparing plant growth across the four scenarios, researchers can determine how varying levels of soil bacteria impact nutrient availability and plant development. Scenario Soil Bacteria Density (cells/g soil) A 1 × 10⁵ B 5 × 10⁵ C 1 × 10⁶ D 2 × 10⁶ Which scenario will result in the least plant growth over the experiment time frame?
