I think it is from the Sun!
Autotrophs(create their own food) are producers like plants.
So its whatever its prey's food diet.
Answer:
The need for continental time zones stemmed directly from the problems of moving passengers and freight over the thousands of miles of rail line that covered North America by the 1880s. Since human beings had first begun keeping track of time, they set their clocks to the local movement of the sun.
During an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product , which are released.
<h3>What is substrate and product ?</h3>
While products can be produced at the end of the reaction, substrates are the reaction's initial raw material. The distinction between a substrate and a product is that a substrate is the substance used to initiate a chemical reaction, whereas a product is the compound formed when the reaction is finished.
<h3>What do you mean by enzymatic reaction ?</h3>
In an enzyme reaction, the free enzyme E binds to its substrate S to form the enzyme-substrate complex (C1), which is then catalyzed into the enzyme-product complex (C2), from which the free enzyme and product P are released: S + E ↔ C1 ↔ C2 → P + E. This is known as the "lock-and-key" model in enzymatic reactions. The great majority of cellular reactions are represented by this paradigm.
Thus from the above conclusion we can say that during an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product , which are released.
