Ecosystems

Energy flows through feeding relationships while matter cycles. Changes in one population or environmental factor can affect others.

What to remember

  • Producers capture energy.
  • Consumers transfer energy through feeding.
  • Decomposers recycle matter.
  • Population changes can alter food webs.
  • Abiotic conditions affect ecosystems.

Key words

producer — organism making food
consumer — organism eating others
decomposer — breaks down dead matter
biotic — living factor
abiotic — non-living environmental factor
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 25 attempts on the same browser.
