Unit 2.5-2.7

What is migration

• Affected by its latitude, longitude, terrain, altitude, land use and nearby water bodies and their current

• Going to a new habitat and adapting to it

• • Ocean species moving further north as water temperature warms

• trait that increases an organism’s fitness

What is Adaptation

• Environmental condition

• Population in an environment

• Crossing over in parent chromosomes creates new combinations of genes

• A new trait that increases an organism’s fitness (ability to survive and reproduce)

Organisms that are better adapted to their env. survive and reproduce more offspring

• Adaptation

• Climate change

• Natural Selection

NGSS.MS-LS4-4

The more rapidly an env. changes, the less likely a species in the env. will be to adapt to those changes

• True

• False

NGSS.HS-LS4-4

NGSS.HS-LS4-5

The more genetic diversity in a population, the better they’re able to adapt to env. change

• True

• False

Primary Succession

• Starts from bare rock in an area with no previous soil formation

• starts from already established soil, in an area where a disturbance (fire/tornado/human land clearing) cleared out the majority of plant life

• Appear after pioneer species have helped develop deeper soil with more nutrients by their cycles of growth/death

• Appear last, after soil is deepened and enriched with nutrients by cycles of growth and death by early & mid successional species

Starts from already established soil, in an area where a disturbance (fire/tornado/human land clearing) cleared out the majority of plant life

• Primary Succession

• Bare rock

• Secondary Succession

• Pioneer or early succession species

Pioneer or early succession species

• appear after pioneer species have helped develop deeper soil with more nutrients by their cycles of growth/death

• Bare rock

• appears after soil is deepened and enriched with nutrients by cycles of growth and death by early & mid successional species

• Appears when the ground is simply bare rock, or bare soil after a disturbance

NGSS.MS-LS2-3

Mid-successional species

• Appear first, when the ground is simply bare rock, or bare soil after a disturbances

• Appear after pioneer species have helped develop deeper soil with more nutrients by their cycles of growth/death

• Appear last, after soil is deepened and enriched with nutrients by cycles of growth and death by early & mid successional species

NGSS.MS-LS2-4

Appears last, after soil is deepened and enriched with nutrients by cycles of growth and death by early & mid successional species

• Late successional or climax community species

• Primary Succession

• Mid-successional species
