Biology 5 -energy Flashcards
Inter specific competition
Organisms compete again other different species for resources
Intraspecific competition
Organisms of same species compete for resources
Which type of competition has the greatest impact on organisms
Intraspecific
Predator-prey cycles are always out of
Phase with eachother
The bottom part of the biomass pyramid shows what
The producer
The bar just above the producer is always what
Primary consumer
Why is the biomass pyramid always a pyramid shape?
Most of the biomass is lost due to heat and energy doesn’t go to the next level
Hence why it’s generally only 5 bars long
Efficiency of energy flow
Energy available for next level
———————————————
Energy that was available from previous level
How is elements returned cycled back to the food chain
By decay
Detritus feeders and microorganisms feed on what causing what
Feed on remains of plants/animals
Releasing O2
What removed carbon from the atmosphere
Photosynthesis from plants
Nitrogen fixation can be done through what two ways
Lighting (enough energy to combine oxygen/nitrogen to give nitrates)
Nitrogen fixing bacteria (converts nitrogen from air into other compounds)
What’s the first stage of the nitrogen cycle
Nitrogen fixation
What’s the 2nd stage of nitrogen cycle
Decomposition
Name two decomposers.
What do they convert
Bacteria / fungi
Dead animals/plants proteins and urea into ammonium
