1. Characteristics of Living Things
In order to be considered a living organism living something must:
Be made of Cells
Grow and Develop
Reproduce
Maintain Homeostasis
Carry Out Metabolic Processes
Contain Genetic Material

2. Hierarchy of Life
Living things are organized into different levels of increasing complexity.
The 3 Levels Include:
Cellular
Organismal
Populational

6. Organism: One Individual Live Thing
Population:

8. Ecology contains both Biotic and Abiotic Factors
Ecology contains both Biotic and Abiotic Factors! What are Biotic and Abiotic factors?
Biotic:
Biological (living) influences upon organisms in an ecosystem.
Ex.: Other organisms (plants, fungi, bacteria,..)
Abiotic:
Physical (nonliving) influences upon organisms in an ecosystem.
Ex.: Climate, Soil, Water

9. Ecosystem: Includes all the living (biotic) and nonliving (abiotic) factors in an area.
Gazelle
Zebra
Elephant
Tree
Abiotic:
Water
Air
Rock
Soil

10. BIOSPHERE: A part of the earth in which life exists to include land, water, air/atmosphere.

11. Habitat-
