Flashcards in Species And Adaptations 2 Deck (6)
How do different species avoid competition in the same habitat
Different species occupy different niches (way organism uses environment) so they tend not to compete with each other unless they occupy the same niche.
Adaptations are characteristics which increase an organisms chance of survival and reproduction in its environment
Co-adaptation definition and examples
Co-adaptation is when 2 species adapt simultaneously.
E.g whistling thorns let ants live in old swollen thorns to deter herbivores.
Ants have a place to live now
What is Evolution process
Evolution process is
Mutation gives rise to new alleles in population
Selection pressure (abiotic/biotic) (predatory/prey/mates/pH/water) occurs, so some struggle to survive.
If there are Individuals with useful alleles they will be more likely survive and pass alleles to offspring
Increased frequency of new allele in population/advantageous allele frequency increases
May give rise to speciation
What is evolution definition
Evolution definition is change in allele frequency within a population in response to a change in selection pressure.
