Lives and harms its host

32
Q

An organism that is fed on by a parasite

33
Q

Predictable changes that occur in a community over time

A

55
Q

Factors that affect all populations in the same way regardless of the population density
Affects everything

A

Density independent factor

56
Q

The higher the population density, the easier it is for a parasite or disease to be transferred from organism to organism

A
