What is the role of producers in an ecosystem?
Producers capture radiant energy from the sun and store it in biological molecules like carbohydrates
How do consumers obtain energy?
Consumers receive energy by eating another organism and taking energy stored in its tissues
What does the ‘10% Rule’ refer to in energy transfer?
Only 10% of the energy in one trophic level is passed on to the next level
What are the three types of pyramids used to represent energy in food chains?
- Pyramid of Numbers
- Pyramid of Biomass
- Pyramid of Energy
What is a disadvantage of the Pyramid of Numbers?
The pyramid shape can be distorted or inverted because the size of the organism is not considered
What does the Pyramid of Biomass measure?
The total dried biomass of organisms found at each trophic level
Why can’t the Pyramid of Biomass accurately show energy transfer?
Different tissue types have different amounts of stored energy and equal mass does not mean equal energy
What is the method used to measure energy in the Pyramid of Energy?
Dry, dead organisms are burned to see how much heat energy is created, measured in Calories or Joules
What percentage of energy is lost to life functions in organisms?
90% of the energy is used by the organism to maintain life functions
What is one advantage of the Pyramid of Energy?
It shows the true energy transfer as per the ‘10% Rule’
What is a disadvantage of the Pyramid of Energy?
It is very difficult to do and the organism is killed in the process
Fill in the blank: The process of energy transfer in ecosystems is not 100% efficient, leading to the concept of the _______.
10% Rule
