Biology Study Notes - Cycling Of Matter

Front 1

Water cycle

Back 1

.

Front 2

Condensation

Back 2

Water vapour is cooled as it rises and turns into water droplets (vapour/gas to liquid droplets)

Front 3

Transpiration

Back 3

Evaporation of water from plants (liquid to gas)

Front 4

Evaporation

Back 4

Water in the liquid form heats up by the Sun's rays causing it to convert from a liquid to a vapour/gas (liquid to gas)

Front 5

Precipitation

Back 5

Result of condensation and falls from the sky as rain, snow, sleet, etc. (vapour/gas to liquid)

Front 6

Surface run-off

Back 6

Water from rain, snowmelt, or other sources, that flows over the land surface

Front 7

Groundwater

Back 7

Water held underground in the soil or in pores and crevices in rock

Front 8

Human influences on the water cycle

Front 9

Carbon cycle

Back 9

.

Front 10

Fossil fuels

Back 10

A natural fuel such as coal or gas, formed in the geological past from the remains of living organisms (ex. coal, oil, natural gas)

Front 11

CO2

Back 11

Carbon dioxide

Front 12

Combustion

Back 12

The process of burning something (ex. the combustion of fossil fuels)

Front 13

Human influences on the carbon cycle

Back 13

.

Front 14

Photosynthesis

Back 14

The process in which the Sun’s energy isconverted into chemical energy (plants only)

6CO₂ + 6H₂O + sunlight → C₆H₁₂O₆ + 6O₂

(carbon dioxide + water + sunlight → glucose + oxygen)

Front 15

Cellular respiration

Back 15

The process by which sugar and oxygen areconverted into carbon dioxide and water, to provide energy for the cell (both plants and animals)

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy

(glucose + oxygen → carbon dioxide + water + energy)
