Explanation:
Animal indicator list is a barometer to check how a particular ecosystem is affecting the lives of particular animals. The indicator measures stress or behavior in the ecosystem to know whether to protect the specie or allow them undisturbed
This is to avoid or reduce to barest minimum incidences of extinction of such specie in the ecosystem.
The grizzly sudden reduction in number from well over 100,000 in California to less than nothing in 1942 triggered the need to protect the grizzlies from human destruction and possible extinction. Grizzlies was a national specie and appeared in the flag of California. The population gradually reduced in most of the states of Idaho, Utah, Alaska and many more.
The grizzlies in 1975 were declared protected species to avoid being hunted or trapped by humans and to repopulate them in the areas where they once lived. Their future will depend largely on humans ability to allow them to coexist with them, by setting out a large area for them to live and regroup.
This will go to balance the ecosystem which has been tampered or disturbed by development.
"The Midwest receives the nickname of "breadbasket" because of the abundant cereal crops it produces for the United States and the world; these crops include wheat, corn and oats. The history of staple cereal crop production in the Midwest dates back to the 1700s. The fertile soils of the Midwestern states and availability of cheap, abundant land proved suitable for launching a large-scale farming effort, ultimately leading to high volume production of predictable and reliable crops" credit to google put it in ur own word
B. The continents on a map looked like they fit together.
A is the theory he proposed <em>after</em> making this observation
C and D would disprove his theory, not support it.
The correct answer is - II and III.
The agribusiness has been helping a lot to the people in the developing countries around the world, mostly with better food supply and the support in the traditional agricultural practices.
The better food supply comes from the proper distribution of the food on the home markets, and it is also food that is produced in the country, not imported one, so everyone sees the benefit from it.
The support in the traditional agricultural practices is also very important, as the farmers are managing to get easy access to the things they need for farming, but also they have secured market for their products. The traditional agricultural practices are also supported as in those ways it is possible to produce organic food, for which there's an ever growing market.
