Question
Chapter 57.4, Problem 1CC
Summary Introduction
To determine: The type of control after applying fertilizer to a bush, which increases spider density on the bush.
Introduction: Bottom down and top-down controls are two control measures of a food web or chain. These control measures are applied in the food chain to regulate the number of species. If one of them gets affected, then the related ones also have an impact.

do you believe that a combination of Insect Pest management techniques (crop rotation, timing of plantings, and timing of tillage and harvest) is better than using only one type? Justify your stand.
In North Carolina and other soybean-producing states, many farmers grow a species of soybean known as Roundup Ready. Roundup is a weed-killing chemical that was produced by Monsanto, (recently purchased by
Bayer). The farmer can directly spray Round-up on his fields and it will kill all the weeds, yet leave the soybean plants unharmed. One particular farmer noticed that after a few years of using Roundup weed killer, it became
less effective, leaving more andynore weeds alive after spraying. Which of the following explanations, best describes why these weeds remained alive?
After years of exposure to Roundup, the soybeans became more resistant to the weed killer.
Roundup-resistant weeds were more likely to survive and reproduce than were non-resistant individuals.
When Bayer bought out Monsanto, they started selling poor-quality Roundup.
Roundup-resistant weeds have less-efficient photosynthetic pathways than the original form.
If raising honeybees as pollinators becomes unprofitable because of colony collapse, what alternatives do farmers have?

Doug and his research team carry out experiments with the plant species Mouse-ear Cress, or Arabidopsis thaliana. They like this species because it is easy to grow in both the lab and field. Arabidopsis is very small and lives for just one year. It grows across most of the globe and in a wide range of latitudes and climates. Arabidopsis is also able to pollinate itself and produce many seeds, making it possible for researchers to grow many individuals to use in their experiments. Doug chose Arabidopsis populations in Scandinavia and the Mediterranean for his research on local adaptation because those two locations have very different climates. The populations may have adapted to have the highest survival and reproduction based on the climate of their home location. To deal with sudden freezes and cold winters in Scandinavia, plants may have evolved freeze tolerance traits, which produces chemicals that act like…arrow_forwardMany plants mimic other plants or other animals in order to attract pollinators. a) Describe one example of plants mimicking either other plants or other animals in order to attract pollinators. b) Why might these “cheating” strategies have evolved rather than developing “truthful” signals to attract a pollinator?arrow_forward

- A scientist is studying the effect a new fertilizer has on root growth on bean seedlings. Three groups of plants are grown in the same location in a greenhouse, each receiving the same amount of sunlight and water every day. The scientist measures the length of the roots for each plant every day. The scientist then calculates the mean for each group for five days. The results are shown in the following table.
