Ecology Chapter 2/ biochemical, cycles/ hydrogen cycle Flashcards
First law of thermodynamics
Energy cannot be created or destroyed, but can be transformed from one form to another
Second law of thermodynamics
During energy transfer, some energy is converted into a useable form called thermal energy
The suns energy
- Almost all energy is from the sun
Albedo
The amount of energy reflected by cloud, water, and land 
Trophic levels
Levels and ecosystems, which energy and matter are exchanged
First trophic level
(Producers )
Has all the chemical energy to fill otHer trophic levels
Other trophic levels
Called consumers or heterotrophs
Decomposers
Can feed at any trophic level
Food webs
Multiple feeding relationships in an ecosystem and multiple food chains in one diagram
Reactants and products of photosynthesis
(Reactants) solar energy, water, carbon dioxide —> glucose (sugar) and oxygen
Reactants and products of cellular respiration
(Reactants) sugar and oxygen —-> KINETIC and HEAT energy
Chemosynthesis
When non-photo synthetic organisms convert in organic chemicals to organic compounds without solar energy
How many trophic levels or food chains limited to
5
What is biochemical cycling
Cycling of nutrients from the environment to organisms and back to the environment
Organic matter
Compounds with carbon and hydrogen atoms
Decay
Decomposition of nonliving things which makes organic matter available for other living things
Hydrological cycle
Movement of water through the biosphere
Water
Universal solvent ,and organisms depend on water to transport nutrients to cells
Cohesion
Attraction between the same two particles ex. Two water particles 
Adhesion
The attraction between two different particles ex. 1 water and 1 glass particle 
What is the biggest reservoir?
Ocean
Where is ground water?
In earths crust
Evaporation
Liquid to vapour
Condensation
Water vapour to liquid
