Some organisms have colorful appearances to warn their predators (animals that would try to eat them) that they are harmful or do not taste good. If other species, that are not harmful, mimic these colors how would that help them reproduce?

• The bright colors would help them attract more mates and allow them to reproduce

• Because they have similar colors they can mate with the harmful species to create hybrids
  

• Bright colors help them be more visible in the dark and most mating occurs after dark

• The similar markings and colors will increase their chance of predators avoiding them and allow them to survive to reproduce

• so that their babies can have friends to play with

• the more offspring the more likely the offspring will survive

• the more offspring the less likely offspring will survive 

• the more offspring the less competition

a bird that can easily outcompete other birds for food and that can produce many eggs has a high

• life expectancy

• mutation rate

• fitness

• adaptability
