Which statement best summarizes the changes in agricultural techniques over time?(1 point)
Over time, humans have decreased the inputs of energy and chemicals in agriculture.
Humans have been using the same agricultural techniques since the beginning of sedentary agriculture.
Over time, agricultural techniques shifted from requiring large inputs of labor to requiring large inputs of energy
and technology.
Over time, agricultural techniques shifted from very expensive to very cheap.
Over time, agricultural techniques shifted from requiring large inputs of labor to requiring large inputs of energy and technology.
The best statement that summarizes the changes in agricultural techniques over time is: "Over time, agricultural techniques shifted from requiring large inputs of labor to requiring large inputs of energy and technology."
Which agricultural system requires the lowest input of labor and energy?(1 point)
The statement that best summarizes the changes in agricultural techniques over time is: "Over time, agricultural techniques shifted from requiring large inputs of labor to requiring large inputs of energy and technology."
To arrive at this answer, let's break down the options and explain the reasoning behind each:
1. "Over time, humans have decreased the inputs of energy and chemicals in agriculture."
This statement is not accurate because, in general, agricultural practices have actually increased the use of energy and chemicals over time. With advancements in technology, farmers have introduced more machinery and chemical inputs to increase productivity.
2. "Humans have been using the same agricultural techniques since the beginning of sedentary agriculture."
This statement is incorrect as well, as agricultural techniques have evolved significantly since the inception of sedentary agriculture. Innovations in tools, practices, and technologies have shaped and transformed agricultural systems over time.
3. "Over time, agricultural techniques shifted from requiring large inputs of labor to requiring large inputs of energy and technology."
This statement accurately highlights the shift in agricultural practices. Initially, agriculture relied heavily on manual labor, with farmers working the land manually. However, with the advent of machinery and technology, energy and technology have become essential inputs in modern agriculture.
4. "Over time, agricultural techniques shifted from very expensive to very cheap."
This statement is generalizing and oversimplifies the matter. While some advancements have made agriculture more efficient and cost-effective, others may have increased costs in terms of equipment, technology, or specialized practices. Thus, it is not accurate to state that agricultural techniques have universally shifted from expensive to cheap.
Therefore, option 3 is the statement that best summarizes the changes in agricultural techniques over time.
