LESSON 1
00:05
BIOTIC FACTORS
00:06
ABIOTIC FACTORS
00:06
BOTH (BIOTIC AND ABIOTIC FACTORS INTERACTIONS)
00:11
BIOTIC FACTORS
00:11
HAVE THE CHARACTERISTICS OF LIFE
00:13
EXAMPLES: plants, animals, and microorganisms.
00:15
Dead things are considered to be biotic since they were once alive or part of a living thing. Once the dead things are completely decomposed by microorganisms, they are considered abiotic. Bone and hair are left behind after the death of an organism that is biotic.
00:21
ABIOTIC FACTORS
00:22
NONLIVING THINGS
00:23
EXAMPLES: WIND, SUNLIGHT, SOIL, TEMPERATURE, ATMOSPHERE, WATER, FIRE, SALINITY, pH LEVELS, ETC.
00:25
DO NOT POSESS THE CHARACTERISTICS OF LIFE
00:31
BOTH BIOTIC & ABIOTIC INTERACTIONS
00:32
BIOTIC FACTORS HAVE TO RELY ON ABIOTIC FACTORS TO SURVIVE.
00:33
EXAMPLES: ECOSYSTEMS; AUTOTROPHS, HETEROTROPHS
00:35
The biotic components of an ecosystem are directly dependent on abiotic components of the ecosystem for survival. When one of the two elements of the ecosystem is destroyed, the whole ecosystem is disrupted.
