1. Biology EOC Review

2. Chapter 8 & 9 – Photosynthesis and Cellular Respiration pg 9
53. What is the formula for photosynthesis?
54. What are the reactants and products?
  Reactants:  
Products:  
CO2 + H2O + Energy → C6H12O6 + O2
Carbon dioxide + water + sunlight → glucose + oxygen
carbon dioxide, water
glucose, oxygen

3. energy, carbon dioxide, water
55. Write the formula for cellular respiration: 56. What are the reactants and what are the products of cellular respiration? Reactants: Products:
C6H12O6 + O2 → CO2 + H2O + Energy
glucose + oxygen → carbon dioxide + ATP + water
glucose, oxygen
energy, carbon dioxide, water

4. 57. Cellular Respiration occurs in (Plants / Animals / Both)?
 58. Photosynthesis occurs in (Plants / Animals / Both)?
 59. Photosynthesis converts solar energy into chemical energy
60. Cellular respiration converts chemical energy (glucose) into different chemical energy (ATP)
61. What factors affect the rate of photosynthesis?
light intensity, color of light, amount of water, temperature, amount of carbon dioxide

5. 91. How does photosynthesis relate to energy getting into ecosystems
91. How does photosynthesis relate to energy getting into ecosystems? 92. What role do decomposers play in the environment? 93. What is a trophic level?
Plants use photosynthesis to make their own food, other organisms then rely on plants for their food, other animals rely on those herbivores
They break down matter so it can be recycled back into the environment
Each level in a food chain or food web (producers, primary consumers, secondary consumers)

6. sun Oak tree – blossoms, nuts, leaves
94. What is the ultimate source of energy for this food web? 95. What are the producers in this food web? 96. What are the primary consumers (herbivores) in this food web? 97. What are the secondary consumers in this food web?
sun
Oak tree – blossoms, nuts, leaves
Bees, deer, mice, rabbit, insects
Wolf, Bear, toad, birds, red fox,

7. Most At the bottom  leaves
98. Create an energy pyramid from the food chain:
leaves → insects → birds → red fox → bear
99. Where is the most energy in this pyramid? Where is the least energy?
Most At the bottom  leaves
Least At the top  bear

8. 100. What happens to energy as it moves through the food chain/web? 101. Assume there are 10,000 kilocalories of energy in the leaves. Estimate the amount of energy in each of the other levels of the energy pyramid.
It is lost as heat
Only 10% of energy is available from the level before:
Bear – 1 kilocalorie
Red fox – 10 kilocalories
Birds – 100 kilocalories
Insects – 1,000 kilocalories
Leaves – 10,000 kilocalories
