Clay- easily waterlogged and forms clumps when wet
loam- different sized particles retains water and does not become waterlogged
sandy- do not retain water and are easily eroded
What is a decomposer
An organism that feeds on and breaks down dead plant or animal matter into inorganic nutrients for photosynthetic producers
Why are decomposers saprotrophs
Because they obtain their energy from dead or waste organic material
What are detritivores
They are organisms that speed up the decay process by feeding on dead and decaying material and break it down into smaller pieces. this increases SA for the decomposers to work on
Prezygotic reproductive barriers
Prevent fertilisation and formation of the zygote
Postzygotic reproductive barriers
Reduce the viability or reproductive potential of offspring
