Answer:

E) 2

Explanation:

The energy transfer through the food chain is not 100% from one consumer to another, or from the producer to the primary consumer, but instead it is around 10%. This means that if a producer has the 100% of energy, as it is the one that produces it, the primary consumer will only get 10% of its energy while consuming it, while the predator of the the primary consumer will only 10% from the primary consumer, or rather only 1% from the energy of the producer. In this case we have 200 kg of plant material. The plant material represents a producer, thus it is the one with 100% of energy. A herbivore will eat the plant material, getting 10% of its energy, thus this plant material is supporting about 20 kg of herbivore. The predator of the herbivore gets only 10% from the herbivore's energy, or only 1% of the producer's energy, thus only 2 kg of predator can be supported by the initial plant material.

A graph of coal reserves in the United States versus time slopes downward. This indicates that coal production could have ______
rjkz [21]
The correct answer is:  [B]:  "decreased" .
________________________________________________________
<u>Note</u>:
________________________________________________________
        In a graph of "coal reserves in the United States" vs. "time" ; 

→ the "time" is the "independent variable" that belongs on the "x-axis" .

→ The quantity or amount of "coal reserves in the United States" is the "dependent variable" that belongs on the "y-axis" . 

       If the graph "slopes downward" ;  this would indicate a "decrease" in the amount/quantity of "coal reserves" over "time" .  

→  As the value of "x" increases — "time" increases — and; as "x" increases, the value of "y" {the amount/quantity of "coal reserves"} decreases.  

→ This would be represented by a "downward sloping" graph;  

→  and, among the answer choices given, could indicate that coal production:
_______________________________________________________
                     →  "decreased" ;    
_______________________________________________________
→  which is:  Answer choice:  [B]:  "decreased" .

Which of these products are made from a renewable resource?
aleksandr82 [10.1K]

Renewable resources are those which can be replaced naturally and repeatedly. For example, water, oxygen, and plants are examples of renewable resources.

Wood is a renewable resource as it is a part of trees. Trees are able to be replanted and can be cut down again, once they reach maturity. Plastics, glass, and steel are known as non-renewable resources as they cannot be replaced at a sufficient rate and usually have a limited supply. For example, plastics are created using a variety of different substances such as natural gas and oil (polyethylene). The Earth contains a limited supply of both substances, so plastic is deemed as being non-renewable.

As a result, the only renewable product in the choices provided above is a wooden spoon.
