Ecosystems

Levels of Organization

100

multiple populations of different species living together

Community:

200

all of the chemical reactions of each cell in an organism that provide energy for life’s processes and create key molecules.

pick a team do do 5 push ups

Metabolism

300

This process can be both sexual and asexual depending on the species

reproduction

400

Which is the correct order of organization. 

A.    Kingdom, class, genus, species, order, phylum, family

B.    Species, genus, family, order, class, phylum, kingdom

C.    Kingdom, phylum, class, order, family, genus, species

D.    Kingdom, order, class, phylum, genus, family, species

C. Kingdom, phylum, class, order, family, genus, species

Binomial Nomenclature: 2-name naming system by this scientist

Carol Linnaeus

Water

100

The 3 MAIN CYCLES that we will study are:

Water (Hydrologic)

Carbon

Nitrogen

200

some water seeps underground from the surface of the Earth.

Aquifer: An underground layer of permeable rock that can hold water.

Infiltration

300

water rises back into the atmosphere as water vapor from plants.

Transpiration:

400

what is the name of this underground layer of porous, honeycombed, water-bearing rock that is between 300-700 feet thick. #2 name the AQUIFER it creates

Limestone - Edwards Aquifer

500

when a body of water becomes overly enriched with nutrients, causing excessive algae growth

Eutrophication

Carbon

100

plants capture CO2 from the atmosphere and use it to make sugar.

BONUS X7

Photosynthesis

200

CO2 released into atmosphere as waste from metabolism.

Cellular Respiration

300

converts carbon from once-living organisms into fossil fuels through intense heat and compression.

Fossilization

400

(like bacteria, earthworms, and fungi) break down dead materials and return nutrients (like carbon) to the soil.

Decomposers

500

when wood or fossil fuels, which contain carbon, are burned causing the release of CO2 in the atmosphere

Combustion

Succession

100

Which organisms are usually the pioneer species in primary succession? 

A) Trees        B) Lichens and mosses      C) Shrubs     D) Birds

B) Lichens and mosses

200

Why does primary succession take longer than secondary succession? A) More disturbances B) Soil must first be created

C) Animals arrive slower D) Fewer pioneer species

B) Soil must first be created

300

Why might areas with frequent disturbances remain dominated by pioneer species? 

A) They never allow soil to form 

B) Disturbances favor quick-growing species 

C) Pioneer species are climax species

D) Soil is destroyed in climax communities

B) Disturbances favor quick-growing species

400

Describe one of the main differences in both primary and secondary succession in terms of their starting points.

while both have the same end point (climax community) they have difference starting points and pioneer species

secondary succession has a head start since it already has multiple layers of living soil

500

What is a climax community? 

A) An unstable ecosystem B) The first community to form on bare rock

C) A mature and stable community 

D) A community destroyed by disturbance

C) A mature and stable community

Nitrogen

100

Bacteria (or lightning!) in the soil or water convert nitrogen (from the air or water) into forms that plants can use

Nitrogen fixation

200

decomposers, like bacteria, break down dead matter, returning nitrogen to the soil.

Decomposition

300

Bacteria convert nitrogen from waste (urine and feces) into ammonia.

Ammonification

400

Name these molecules.

NH4     NO3      CO2          N2

ammonium

nitrate

carbon dioxide

atmospheric nitrogen

500

bacteria convert nitrogen in ammonia to N2 so it can go back into the atmosphere 

BONUS X3

Denitrification

Mixed Bag

100

sun heats liquid water to vapor and it rises to the atmosphere 

Evaporation

200

Put these molecules in order

NH4        N2        NO3          NO2

N2, NH4, NO2, NO3

300

German Scientist developed system to extract atomospheric N2 into ammonium nitrate

Fritz Haber

Random dispersion pattern

500

the theoretical maximum population that a given environment could support

BONUS TAKE AWAY 500 POINTS FROM ANOTHER GROUP

Carrying Capacity

Population

100

Aspects of the environment that limit the size a population can reach

BONUS  x 10

Limiting factors

200

 limiting factors have a bigger impact on more dense populations.

These are factors that can be triggered by an increase in population size, and thus

Density-dependent

300

There are two kinds of limiting factors

biotic and abiotic

400

what kind of pattern AND give an example of a species that follows this pattern

clumped dispersion pattern

500

exponential growth pattern
