Question

increased competition, presence of predators, and decreased shelter availability lead to slow growth. what does \k\ represent in a population graph? environmental resistance carrying capacity the actual population size growth rate

Explanation:

In population ecology, the letter "K" is a standard symbol representing the carrying capacity of an environment. The carrying capacity is the maximum number of individuals of a particular species that an environment can support over a sustained period, considering factors like available resources (food, water, shelter), space, and interactions with other species (such as competition and predation). As shown in the graph, the population size approaches and stabilizes near the "Carrying capacity" line (represented by the red dashed line), which aligns with the definition of \( K \). Environmental resistance refers to factors that limit population growth (like those mentioned in the text above the graph: increased competition, predators, decreased shelter), but it's not symbolized by \( K \). The actual population size would be the value of the population at a specific time (represented by the blue curve's y - value at a given x - value), and the growth rate is related to the slope of the population - time curve (how quickly the population size is changing over time), not \( K \).

Answer:

B. carrying capacity
