Chapter 24, Problem 1CTS
Summary Introduction
To describe:
The risk and benefit of relying a few agricultural species.
Concerns about lack of diversity in agricultural production.
Introduction:
The crops are the plants, which are grown and harvested by humans for profit or substantial requirement. There are very few plants, which can be used as crops.

- a) Classify each of the following as intensive or extensive farming: i) poultry and eggs; ii) dairy farming; iii) hog production; iv) cattle ranching; v) wheat and other grains; vi) oilseeds (e.g., canola and sunflower); vii) fruits and vegetables; viii) sheep and goats. b) Choose two types each of intensive and extensive farming. How do the descriptions of intensive farming and extensive farming apply to these types of farming?arrow_forwardDescribe two 'beneficial' aspects from the last 10,000 years of humanity, as well as two 'dis-advantageous' aspects. Agriculture should be your guiding point here.arrow_forward(10)Sustainable agriculture consists of farming and grazing that maintain the healthy soil, clean water, pollinators, genetic diversity, and other resources needed for the production of crops and livestock over the long term. Strategies undertaken toward this end include all of the following EXCEPT: Increased use of new fertilizers without waiting years to test their viability moving back toward the more traditional model of agriculture genetic engineering of crops and livestock Reduction of fossil fuel inputsarrow_forward
- Organisms that damage crop plants are the most costly of introduced species. Weeds, pathogenic microbes, and arthropods that attack crops together account for half of the costs documented by Pimentel and his colleagues. What steps can we—farmers, governments, and all of us as a society—take to minimize the impacts of invasive species on crops?arrow_forward1. what is a crop: 2. Food has to be produced on a large scale. Give reason. 3. What are rabi crops? 4. What are kharif crops? 5. Give example for plants belonging to Leguminosae family. 6. Why paddy cannot be grown in the winter season? 7. What is ploughing? 8. How do you separate good, healthy seeds from damaged ones? 10. What is compost? 11. What is Crop Rotation? 13. What is animal husbandry?arrow_forwardCorn undergoes C4 photosynthesis and does not fix nitrogen, whereas Alfalfa is a nitrogen-fixing plant that utilizes C3 photosynthesis. Both species are equally watered. What can you interpret from this dN/dt vs. N plot given the biculture and monoculture treatments for each species (alfalfa & corn)? Biculture: Both corn & alfalfa grown together in the same pot Monoculture: Corn & alfalfa grown in separate potsarrow_forward
- Which of the following is true of India? The dramatic decrease in the number of rice varieties planted puts the food supply at risk. O Use of pesticides have remained stable over the past century. There has been an increase in the diversity of corn crops due to deliberate efforts. Antibiotic resistance is unlikely to be a problem. The effects of climate change are unlikely to have strong effects on agriculture.arrow_forwardIn 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.arrow_forwardWhat is sustainable agriculture?

- With regard to industrial agriculture, it is distinct from traditional agriculture in that: Its development tends toward monocultures Its development tends toward polycultures Its development involves an equal blend of monocultures with polycultures It is less well integrated into market economies, producing less excess food to sellarrow_forwardHow would you our reconcile the emerging needs of human beings regarding their health and the need to protect the growth of biodiversity? Do you think that earth can exist without human beings taking care of it? Or biodivesity also needs human beings for it to be in continous growing process? What are small ways that you think would promote safekeeping our biodiversity? What do you think are the common human activities that can harm biodiversity? What would be the consequences if these human activities might be stopped and prohibited?arrow_forwardSocial inequality, violence, warfare, disease, overpopulation, environmental degradation, lower health and nutritional quality. These are some of the direct impacts of the development of agriculture. Given all the social and biological ills associated with the shift from being hunter-gatherers to agriculture, it has been said that agriculture is the “worst mistake in the history of the human race?” (https://www.discovermagazine.com/planet-earth/the-worst-mistake-in-the-history-of-the-human-race).
