Question

Quizplus · Accepted Answer

Invertebrate grazers often have a greater impact on host plants because they tend to specialize on specific plant parts or species, can have high population densities, and their feeding can lead to significant damage or stress on plants. Vertebrate grazers, like bison, often have a broader diet and their grazing can sometimes even benefit plant communities by preventing any single species from becoming dominant.
