Announcement
assignment include filling tables in page 149,
150, 151, 152, 153 and 154. Two graphs
demonstrating changes in frequency and another
two demonstrating changes in fitness values of
both predator and prey

Ecological interactions between organisms
1-Competition two organisms using the same
resources 2-Predator-prey (parasite-host
interactions) benefit itself while harming
another 3-Mutualism both participants benefit
from an interaction 4-Commensalism one
participant benefit while is unaffected 5-Amensali
sm one participant is harmed but the other is
unaffected

Natural selection(Adaptation)
Traits (genetic makeup) that confer superiority
in survival and reproduction to their
owner. Organisms interactions involve reciprocal
changes over time. This kind of evolutionary
is termed coevolution. Fitness genotype
reproductive contribution to
subsequent generation
