Given what we know, we can confirm that the correct option is D, which states that "<em><u>They are used by living things as the </u></em><em><u>main source </u></em><em><u>of </u></em><em><u>energy</u></em>."
<h3>What are carbohydrates?</h3>
- They are the primary source of energy for most cells.
- They are what we refer to as sugars.
- The main example of this is glucose.
- They are formed by monomers called monosaccharides.
Therefore, we can confirm that since carbohydrates are what we refer to as sugars, which include molecules like glucose and this is the main source of energy for most cells, option D is the correct choice.

There are 2 stages in photosynthesis
light stage and dark stage
light stage takes placein the grana because there's presence of chlorophyll. 2 reactions take place here.
1. photolysis of water where water molecules are split into hydrogen ions and oxygen gas in presence of chlorophyll and oxygen gas. the oxygen gas is released into the atmosphere but hydrogen ions are used in dark stage.
2. formation of adenosine triphosphate which is formed by combination of adenosine diphosphate and an inorganic phosphate in presence of light. this adenosine triphosphate is also used in dark stage
dark stage is a light independent stage which takes place in the stroma. energy is provided by adenosine triphosphate formed in the light stage. this stage involves tge combination of carbon(iv)oxide and hydrogen ions to form a simple carbohydrate and a water molecule. this process is known as carbon(iv)oxide fixation which is the reduction of carbon(iv)oxideby hydrogen ions using adenosine triphosphate energy to form a simple carbohydrate.
This simple carbohydrate is changed to glucose for use in the plant or to starch for storage
Answer:
<h2>
C) circulatory-transports materials for energy</h2>
Explanation:
Excretory system - the elimination of wastes produced by homeostasis.
Digestive system - the conversion food into energy and basic nutrients to feed the entire body.
Circulatory system - carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
Respiratory system - allows your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood.
