Front of card Back of card

Each organism has a 2 part scientific name: Genus and species.

17

Dichotomous Key

Front of card Back of card

A device that can be used to easily identify an unknown organism.

18

Biogeochemical cycle

Front of card Back of card

Cycle of transferring nutrients from the environment to an organism and back.

19

Open Ecosystem

Front of card Back of card

Energy and matter can flow in & out.

20

3 processes in Water

cycle

Front of card Back of card

Cellular respiration – gives off waterTranspiration – loss of water through leaves.Photosynthesis – uses water

21

Precipitation

Front of card Back of card

Rain, snow, sleet or hail

22

Standing water

Front of card Back of card

Holds water on land Lakes & swamps.

23

Ground Water

Front of card Back of card

Holds water underground

24

Evaporation

Front of card Back of card

Water changes from liquid to gas.

25

Condensation

Front of card Back of card

Water changes from gas to liquid.CLOUDS

26

Run-off

Front of card Back of card

Returns water to oceans, lakes, streams.

27

Acid Rain

Front of card Back of card

Precipitation with a low pH. Caused by sulfur dioxide (g) & nitrous oxides (g)

28

Sulfur dioxide

Front of card Back of card

From industries. Mixes with water in air to make sulfuric acid.

29

Nitrous Oxides

Front of card Back of card

From fertilizers and car exhaust. Mix with water to form nitric acid.

30

Effects of Acid Rain

Front of card Back of card

Kill crops, forests, fish, soil bacteria. Corrodes metals.

31

Solutions for Acid Rain

Front of card Back of card

Scrubbers in smoke stacks, add lime(chemical) to lakes to pH. Less car emissions. Walk, ride bike, take bus…

32

Carbon in Living Things

Front of card Back of card

Trapped and stored by photosynthesis and chemosynthesis.Released by respiration, decomposition, and combustion.

33

Carbon in non-living

things

Front of card Back of card

Most carbon is found in oceans and rocks, shells and corals.

Only 0.03% of atmosphere is CO2

34

Respiration

Front of card Back of card

Uses O2 and releases CO2

35

Combustion

Front of card Back of card

Uses O2 and releases CO2

36

Decomposition

Front of card Back of card

Uses O2 and releases CO2

37

Photosynthesis

Front of card Back of card

Uses CO2

and releases O2

38

Chemosynthesis

Front of card Back of card

Uses CO2 to make C6H12O6

Happens near deep sea vents on bottom of ocean

39

Greenhouse Effect

Front of card Back of card

CO2 in atmosphere traps heat in. Due to burning of fossil fuels and deforestation.

40

Solutions toGreenhouse

Effect

Front of card Back of card

Decrease burning of fossil fuels and deforestation.

41

Ozone holes

Front of card Back of card

Ozone (O3) is broken down by CFCs causing holes in the layer. Ozone protects earth from UV radiation.

42

Effects of Ozone holes

Front of card Back of card

Skin cancer, eye problems and aging of skin.

43

What nitrogen is used for.

Front of card Back of card

1. Proteins (amino acids)

2. Cells3. Nucleic acids – DNA & RNA

44

3 parts of Nitrogen

cycle

Front of card Back of card1. Nitrogen fixation (bacteria and lightening convert N2(g) to NO3-)2. Nitrification (cycle)3. Denitrification (NO3-
