Life Science

Life Science…• deals with the structure and

behavior of living organisms, their organization, life processes, and relationships to each other and their environment

• includes biology, medicine, anthropology, ecology,biochemistry, botany, cell biology, genetics, molecular biology, etc.

Life Science Topics• Environmental Science

• Biomes• Animals• Plants• Habitat• Adaptations• Animal Interactions• Ecology

• The Human Body • Health • Body Systems• Nutrition• Genetics

Habitat – place where organism lives and obtains its energy

• Need to compete to get the most resources from your habitat

• Need to develop special characteristics or strategies to beat everyone else

Competition – struggle between organisms to survive in a habitat with limited resources

• Adaptation – behaviors and physical characteristics of organisms that allow them to survive in their environment

And the Winner is…

• Adaptations come from random mutations• Animal doesn’t plan something, but a

behavior or physical characteristic gives them an advantage over others

• E.g. Cheetah

• Natural Selection – process in which individuals that are better adapted to environment are more likely to survive and reproduce

Predation – interaction when one organism kills and eats another

• Predator – killer organism

• Prey – organism that is killed

Predator adaptations:Cheetah – speedJellyfish – stinging tentaclesPitcher plant – rotting smell

Prey adaptations:Protective coveringsToxins Warning colors (red, orange)Camouflage – hide wellMimicry – look like something elseFalse Coloring - eyespots

Food chain – series of events when one organism eats another and obtains energy
