Chapter 55.2, Problem 2R
Summary Introduction
To review:
The characteristics of herbivory and parasitism that helps in promoting specialization.
Introduction:
The consumption of the plant parts by different organisms present in the environment is known as herbivory. Parasitism may be defined as the interaction where the

In some circumstances, grasses that initially lose tissues from being consumed by animals such as elk or cattle regrow more than they would have otherwise, and benefit from the moderate levels of grazing. Which of the following terms would best describe such a plant-herbivore interaction?a) Commensalismb) Mutualismc) Predationd) Parasitism
What are the dynamics of pests, parasites, and pathogens, including the various control strategies?
Integrated pest management deals with the prevention and suppression of harmful organisms and long-term effects on the environment. Good agricultural practices in plant protection include weed control. Why is weed control important to agriculture production?
A) weeds compete with crops for nutrients
B) weeds compete with crops for moisture
C) weeds compete with plants for sunlight
D) weeds compete with plants and crops for nutrients, moisture, and sunlight

- How is integrated pest management (IPM) different from other forms of pest control? O IPM only supports mechanical control of pests in an area. O IPM tolerates a low number of pests in an area. O IPM favors the generation of herbicide-resistant weeds. O IPM prohibits the use of herbicides in an area. O IPM suggests the use of herbicide-resistant plants.arrow_forwardWhat are the effective pesticides in farming?arrow_forwardc) Suppose you count the number of seeds produced by milkweed plants in different habitats with variable numbers of herbivores present.
