Biology B3.3 B - Transferring biomass
Cards in this deck (9)
- 1What are trophic levels?Different levels in a food chain
- 2What are producers, & what trophic level are they on?Organisms that make their own food. They are on trophic level 1.
- 3What are primary consumers, & what trophic level are they on?Herbivores that eat producers. They are on trophic level 2.
- 4What are secondary consumers, & what trophic level are they on?They are carnivores & omnivores that eat primary consumers. They are on trophic level 3.
- 5What are tertiary consumers, & what trophic level are they on?Carnivores & omnivores that eat secondary consumers They are on trophic level 4+.
- 6What is an apex predator?Organisms that have no predators & are at the top of the food chain.
- 7What is a pyramid of numbers? (FUN FACT! doesn't always look like a pyramid)A model to represent the different trophic levels. The number of organisms in each level is represented by a bar.
- 8Why isn't all the biomass transferred from one organism to another?+ Some parts of an organism are not eaten
+ Some parts are not digested
+ Some biomass is used up in cellular respiration - 9How do we work out the efficiency of biomass transfer?average biomass in higher level / average biomass in lower x 100
