NGSS.MS-LS2-3

Struggle between organisms of the same or different species for food, space, light, water, etc.

• Competition

• Adaptation

• Runoff

Tags

NGSS.MS-LS2-4

NGSS.MS-LS2-2

Environmental change that impacts the environment over long periods of time, so organisms may be able to adapt (climate change, pollution, large asteroid impact)

• short term environmental change

• long term environmental change

NGSS.HS-LS2-6

NGSS.HS-LS4-5

Process by which organisms that are suited to a particular environment are better able to survive and reproduce than other organisms that are not.

• Competition

• Natural Selection

• Biodiversity

Tags

NGSS.MS-LS4-4

Variety of life.

NGSS.MS-LS2-5

NGSS.MS-LS4-2

Overflow of water from the land and into a body of water.

• Runoff

• Ecological Succession

• Biodiversity

Environmental change that impacts the environment immediately, so organisms do not have time to adapt; they must migrate or die (flood, volcanic eruption, fire)

• short term environmental change

• long term environmental change

Tags

NGSS.MS-LS2-4

Taking more from the land (or sea) than it can replace such as extreme farming, fishing and using fresh water.

• artificial reef

• overharvesting

• competition
