Ken wrote a few steps to describe how carbon circulates between the atmosphere and living organisms. Step 1 is missing. Step 1: Step 2: Plants use carbon dioxide to make glucose Step 3: Plant-eating animals consume the glucose present in plants Step 4: Animals exhale carbon dioxide Which of the following best describes step 1? (1 point) Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Dead animals are buried and form fossil fuels, which produce glucose on combustion. Dead animals decompose and recycle the carbon in the form of oxygen and water vapor. Carbon dioxide in the atmosphere is converted into glucose by animals during respiration.
Carbon enters the atmosphere as carbon dioxide from respiration and combustion.
Which process takes place in both plant and animal cells? (1 point) Conversion of solar energy Cellular respiration Formation of glucose Photosynthesis
Cellular respiration
The table below shows the role of different substances during photosynthesis. (Flip for table) Which of the following statements would correct one of the roles listed in the table? (1 point) Water combines with oxygen to form glucose. Water is formed with sugar during photosynthesis. Sunlight is not transformed into other forms of energy. Chlorophyll absorbs the light needed for photosynthesis.
Chlorophyll absorbs the light needed for photosynthesis.
During which of the following processes would carbon most likely be stored? (1 point) Burning of coal Formation of fossil fuels Respiration Volcanic eruption
Formation of fossil fuels
Which statement is correct about the mass of carbon dioxide used during photosynthesis? (1 point) It is equal to the total mass of oxygen used. It is less than the total amount of glucose and water used. It is equal to the total mass of glucose and oxygen formed. It is less than the total mass of glucose and oxygen formed.
It is less than the total mass of glucose and oxygen formed.
Which of the following substances is formed deep under Earth? (1 point) Chlorophyll Glucose Oil Oxygen
Oil
Hugh described two substances which participate in photosynthesis-- Substance A: Source of energy for plant-eating animals Substance B: Combines with sunlight and carbon dioxide Which statement is correct? (1 point) Substance A is water and Substance B is oxygen. Substance A is glucose and Substance B is water. Substance A is water and Substance B is chlorophyll. Substance A is chlorophyll and Substance B is oxygen.
Substance A is glucose and Substance B is water.
Look at the following diagram of the carbon cycle. (Flip) Which of the following facts is best represented by the arrow pointing from C to A? The energy stored in atmospheric carbon dioxide is conserved because it is used to create new forms of energy present in decomposed plants. The energy stored in atmospheric carbon dioxide is conserved because it is transformed into glucose during photosynthesis. The chemical energy present in carbon dioxide is reduced when it is converted into chemical energy in glucose. The chemical energy present in carbon dioxide is used up completely during the burning of trees.
The energy stored in atmospheric carbon dioxide is conserved because it is transformed into glucose during photosynthesis.
During cellular respiration, which of the following is equal to the total number of carbon, hydrogen, and oxygen atoms in water and carbon dioxide? (1 point) Number of carbon, hydrogen, and oxygen atoms in glucose Number of carbon, hydrogen, and oxygen atoms in oxygen gas Total number of carbon, hydrogen, and oxygen atoms in glucose and oxygen Total number of carbon, hydrogen, and oxygen atoms in hydrogen gas and oxygen
Total number of carbon, hydrogen, and oxygen atoms in glucose and oxygen
