4.1 ecology Flashcards
Biomass
The total amount of organisms or weight.
Productivity
The rate in which energy is added to an organism.
Efficiency
The ability for protien to nurish an organism.
What are the three inputs of photosynthesis?
Light, carbon dioxide, & water.
What are the outputs of photosynthesis?
Oxygen and glucose.
What are the inputs of respiration?
Oxygen and glucose.
What are the outputs of respiration?
Light, carbon dioxide, & water.
What type of organisms perform the processes of photosynthesis and cellular respiration?
Plants
What is shown in a pyramid of energy vs. a pyramid of numbers vs. a pyramid of biomass?
A pyramid of energy shows the energy flow from the producers through the consumers.
A pyramid of numbers shows how many animals or organims there are in the levels of the food chain.
A pyramid of biomass shows how much of an organism or animal is on each level.
Why it is considered more efficient to eat at a lower trophic level vs. a higher trophic level?
When a producer is eaten, automatically 10% of the energy is lost. As the animal lives and continues, the energy will be burned off. As we reached the top of the food cahin, most of the energy is gone, since most of it was burned or used.
