Answer:
The answer is option D "Machines have replaced much of the manual labor once needed to run a farm."
Explanation:
* Progress in Engineering: This simply means how technological machines like heavy tractors which are now used and are helpful in farming are  evolving, meaning they are being used in a larger quantity now.
* Natural Environment: This is the normal way of life or doing things which individuals find themselves practicing in a particular society and at a particular point in time.
* As a result of the machines being developed as an Engineering progress which serves the work of people on the farms, there tends to be less manual labor that would be initially required to run a farm. The machines are now serving the work of human beings (laborers) now.

Hi!
Energy will flow through an ecosystem in one <em>direction, </em>from the sun or inorganic compounds to<em> autotrophs </em>and then to various <em>heterotrophs. </em>
The energy flow in an area will be delivering light energy to <em>autotrophs</em>, which make their food from the energy the sun produces. 
The energy flow also delivers energy via inorganic compounds to <em>heterotrophs</em>, which do not make their own food.
Hopefully, this helps! =)
        
             
        
        
        
Answer:
Lipolysis
Gluconeogenesis
Ketogenesis
Explanation:
The physiological responses to starvation follows the below steps;
- Change of carbohydrate metabolism to fat metabolism
- Glycogen stores are depleted
- Increase in gluconeogenesis occurs in 1 to 2 days of starvation
- Ketogenesis takes over due to decreased insulin levels 
- Increased starvation from this step leads to protein catabolism and then organ failures
