Environmental Science Week 4 Flashcards
Ability to do work
Energy
Energy in motion
Kinetic
Energy at rest
Potential
Biotic (living) components
a. Producers
b. Consumers
c. Decomposers
called autotrophs, they manufacture their own food
Producers
Called heterotrophs, the cannot produce their own food.
Consumers
are fungi and bacteria that convert organic compounds into inorganic forms which can be used again by living organisms.
Decomposers
Abiotic (non-living components)
a. Light
b. Temperature/Climate
c. Soil
d. Water
e. Wind/Air
plants that live in areas submerged in water
Hydrophytes
found in neither wet or dry environment
Mesophytes
found in almost waterless environment
Xerophytes
deals with how energy is transferred in natural processes. It deals specifically with the relationship between heat, work and energy.
Thermodynamics
Energy may be transferred into a system. It may be transformed from one form to another.
First Law of thermodynamics
With each successive energy transfer or transformation, less energy is available for work.
Second Law of thermodynamics
Matter and energy cannot be created nor destroyed but can be transformed or transferred from one form to another
Laws of conservation of matter and energy
