Selection Pressure |
A factor which determines the survival of different species within certain environments. Some species may be unable to survive in some environments and as a result adapt and change over time |
|
|
Evolution due to natural selection |
1. organisms must vary in traits 2. must be selection pressures on these traits and fitness to produce offspring 3. must be an inheritance mechanism capable of passing these traits to offspring |
|
|
Negative selection pressure |
a change in an environment resulting in limited resources, causes competition |
|
|
Negative selection pressure |
a change in an environment resulting in limited resources, causes competition |
|
|
Positive selection pressure |
Factors that increase the chance of a species surviving to reproduce |
|
|
Allelopathy |
production of biomolecules released by plants to inhibit growth of surrounding plants eg. black walnut tree reduces competition from nearby plants |
|
|
Parasitism |
a symbiotic relationship where one organism benefits and another suffers eg. fleas and ticks |
|
|
Mutualism |
symbiotic relationship where both species benefit eg. acacia ants defend acacia trees, trees house the ants |
|
|
Mutualism |
symbiotic relationship where both species benefit eg. acacia ants defend acacia trees, trees house the ants |
|
|
Commensalism |
a symbiotic relationship where organism benefits and another is unaffected eg. barnacles feeding from whales |
|
