A Small Group of Leaf-Feeding Beetles Locates a Field of Snap

question 31

Multiple Choice

A small group of leaf-feeding beetles locates a field of snap beans, one of the preferred plants for this species. At first, the population grows rapidly in the snap bean field, but as the beetle population grows larger, predators, such as spiders and birds, discover the beetles and start to remove individuals from the population. Competition for mates, food, and oviposition (egg-laying) sites intensifies for the individuals in the beetle population as population density increases. A fungal disease also starts to kill many of the beetles. The population no longer grows rapidly but levels off. How would you describe the factors limiting the beetle population?

• A) The factors are density-independent factors.
• B) The factors are density-dependent factors.
• C) The factors act on the population as the population density increases.
• D) Both A and C describe these factors.
• E) Both B and C describe these factors.
