What do detritivores do? |
feed on detritus (dead and decaying material) increase the rate of decay by increasing its surface area |
|
|
What three things will increase rate of decay? |
+temperature +oxygen +water |
|
|
How dies increasing temperature increase decay rate? |
Increase respiration rate of fungi. |
|
|
How does increasing oxygen levels increase decay rate? |
Bacteria will use aerobic respiration to grow and reproduce faster. |
|
|
How does increasing levels of water increase rate of decay? |
+growth & reproduction of bacteria and fungi material will be digested & absorbed more |
|
|
What food preservation methods reduce decay rate? |
canning (vacuum to prevent entry of oxygen cooling (slow down growth and reproduction) freezing (kill & slow down growth & reproduction) drying (removes water so can't feed or grow) add vinegar (acidic conditions kill) |
