Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

15 notecards = 4 pages (4 cards per page)

Chapter 21

front 1

How does the movement of energy and nutrients through an ecosystem differ?

back 1

Energy only moves through biotic components while nutrients move through biotic AND abiotic components, sometimes spending longer in "pools".

front 2

Identify the 7 major nutrients and give examples of what organisms need them for.

back 2

nitrogen- for amino acids, nucleic acids,

phosphorus-

sulphur-

potassium-

calcium-

magnesium-

iron- making hemoglobin,

front 3

Describe the processes in the hydrologic cycle.

back 3

Evaporation (from bodies of water, soil, and plants), transpiration and precipitation (rain, hail, sleet, or snow)

front 4

how can human activities affect the processes in the hydrologic cycle?

back 4

  • In developed areas, building materials reduce the amount of surface area able to absorb water, increasing surface runoff, decreasing groundwater replenishment
  • increase in surface runoff increases erosion
  • Reducing terrestrial plant biomass increases surface runoff, erosion and flooding
  • Sometimes we use groundwater faster than it's being replenished
  • Affecting global warming may increase the speed at which water moves through the hydrological cycle

front 5

Describe the 3 processes that return carbon dioxide to the atmosphere

back 5

Respiration- a by-product of organisms that metabolize oxygen

Rock weathering and volcanic eruptions- carbon is stored in rocks, these processes offset carbon burial

Combustion- carbon stored in organic material can be released through fire and the burning of fossil fuels

front 6

Explain how human activity has caused an increase in atmospheric CO2 concentration, and why this is a concern.

back 6

The burning of fossil fuels releases CO2 into the atmosphere at really high rates, much higher than would ever occur naturally. CO2 is a greenhouse gas so increased CO2 means a warmer planet.

front 7

Describe what the bacteria in the root nodules of legumes are doing when they fix nitrogen.

back 7

no data

front 8

Explain how human activity has altered the nitrogen cycle

no data

front 9

Explain what is weathering

front 10

Define eutrophication

back 10

no data

front 11

Explain how eutrophication can lead to ‘dead zones’ in lakes and oceans.

back 11

no data

front 12

List the main processes whereby detritus is decomposed in terrestrial ecosystems

back 12

no data

front 13

Which organisms are most responsible for the main processes whereby detritus is decomposed in terrestrial ecosystems

back 13

no data

front 14

Predict the relative rate of decomposition based on temperature, precipitation, or lignin content

back 14

no data

front 15

Design an experiment to measure how much the rate of decomposition is affected by the presence of invertebrates.
