As you may know, trees are used to make things like furniture, cottages and paper. Unused paper is then 'thrown in the recycling bin' and recycled (go through the same system to be reused). Deciduous tree leaves specifically, fall off in Autumn so the sticks, trunk, and remains of the tree can be used to make products with the nutrients in the wood. I think this is part of an ecosystem - hope I help! :D
        
                    
             
        
        
        
Answer:
Ocean-Ocean Divergent
Continent-Continent Transform
Continent-Continent Convergent
Continent-Ocean Convergent
Ocean-Ocean Transform
Continent-Ocean Convergent
Continent-Continent Divergent
Explanation:
The above all sites are possible to generate earthquake . The divergent boundary whether it is Continent-Continent or Ocean-Ocean can generate shallow earthquake although it's very weak . The transform plate boundary or strike slip plate motion also generate shallow but powerful earthquake ( example: San Andres Fault is a transform plate boundary) . Another one is convergent boundary which can generate deep and very powerful earthquake .

The correct answer is - grow wheat or oats.
The Great Plains region is a semi arid region. That means that it has relatively low amount of precipitation. Also, the precipitation occurs only in certain parts of the year, and there's relatively long droughts in between. This has led to the Great Plains region to naturally be a grassland. The grasses have contributed with their quick decomposition for a very fertile soil with deep top humus layer. In order to use the soil, the climate conditions, as well as to retain the soil's high productivity, the farmers have mainly orientated towards the farming of crops like the wheat and the oats. They do not require a lot of water, have characteristics that make them suitable for the climate, and their roots and leftovers from the steams are decomposing very quickly which retains the soil's fertility.
