MS-LS4-5 (7th)

The environment is constantly changing due to weather patterns, geological events, and human activity.

If a species cannot adjust to these changes in order to successfully reproduce, then it is MOST likely that the species will

• Develop new adaptations to accommodate for the environmental changes

• Become extinct.

• Form a new symbiotic relationship with another species

• Migrate to a new environment that will meet its needs.

The struggle between organisms to survive in a habitat with limited resources is called

• competition.

• predation.

• symbiosis.

• parasitism.

MS-LS4-5. In ________________ humans have the capacity to influence certain characteristics of organisms by selective breeding.

• adaptation

• natural selection

• artificial selection

• mutations
