Study of living and non-living things and their relationships.

1

Biotic


living thingsPlants & animals

2

Abiotic


Non-living thingsSunlight, soil, rocks, temp.

3

Limiting Factors


Any resource or condition that lowers the success of an organism.Competition, predators, space, temp.

4

Levels in the Biosphere


Orange People Can’t Ever Be BlueOrganism, Population, Community, Ecosystem, Biome, Biosphere

5

Organism


A living thing

6

Population


A group of organisms of the same species, place & time.

7

Community


2 or more populations in an area.

8

Ecosystem


Community and biotic and abiotic factors.

9

Biome


Large ecosystem based on climateEx. rainforest, tundra, grassland

10

Biosphere


Part of earth that can sustain life.

11

Taxonomy


The study of the classification of living things.

12

Taxon (hierarchical classificatio

n)


Did King Philip Come Over For Grape Soda?

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species (general specific)

13

3 Domains


Archaea – ancient bacteriaEubacteria – true bacteriaEukarya - eukaryotes

14

6 Kingdoms


Archaea Eubacteria ProtistaFungiAnimaliaPlantae

15

Species


A group of organisms capable of interbreeding and producing fertile offspring.

16

Binomial Nomenclatur

e


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

17

Dichotomous Key


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

18

Biogeochemical cycle


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

19

Open Ecosystem


Energy and matter can flow in & out.

20

3 processes in Water

cycle


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

21

Precipitation


Rain, snow, sleet or hail

22

Standing water


Holds water on land Lakes & swamps.

23

Ground Water


Holds water underground

24

Evaporation


Water changes from liquid to gas.

25

Condensation


Water changes from gas to liquid.CLOUDS

26

Run-off


Returns water to oceans, lakes, streams.

27

Acid Rain


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

28

Sulfur dioxide


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

29

Nitrous Oxides


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

30

Effects of Acid Rain


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

31

Solutions for Acid Rain


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

32

Carbon in Living Things


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

33

Carbon in non-living

things


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

Only 0.03% of atmosphere is CO2

34

Respiration


Uses O2 and releases CO2

35

Combustion



36

Decomposition



37

Photosynthesis


Uses CO2

and releases O2

38

Chemosynthesis


Uses CO2 to make C6H12O6

Happens near deep sea vents on bottom of ocean

39

Greenhouse Effect


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

40

Solutions toGreenhouse

Effect


Decrease burning of fossil fuels and deforestation.

41

Ozone holes


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

42

Effects of Ozone holes


Skin cancer, eye problems and aging of skin.

43

What nitrogen is used for.


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-

converted to N2(g) by anaerobic bacteria)
