NGSS.MS-LS4-4

Definition: adaptation

• inherited characteristic that increases chances of survival

• organisms with traits well suited to their environment survive and reproduce at a greater rate

• a growing population causes a scarcity of resources

• differences in the DNA sequence

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the trait is an acquired phenotype.

What is the main difference between primary and secondary ecological succession?

• Primary begins WITHOUT soil; Secondary begins WITH soil

• Primary is the first state and secondary is the second stage

• Primary builds plant community; secondary builds animal community.

• Primary begins WITH soil; Secondary begins WITHOUT soil

What is an example of an area that is likely to undergo primary succession?

• Glaciers melt and leave exposed rock

• Plants die from drought and decompose

• Land is bulldozed and soil remains
