Use what you know about natural selection to fill in the blanks in the hypothesis. it should answer the lab question, “what is the effect of the type of food available on the frequency of different types of bird beaks? ” hypothesis: if the type of food available changes, then…

 The blank in the question can be filled as-

If the type of food available changes, then over the passage of time, evolution of different beak types will result  that reflects adaptation according to the changing food habits because their body wants to adapt in order to survive and reproduce ( pass their genes to the next generation) under the changing conditions.

Therefore, the frequency of allele corresponding to beak will be enhanced or increased.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
