Sustainablity

meeting the needs of the present without compromising the ability of future generations to meet their own needs

Examples Sustainable resources

Biomass, Hydropower, geothermal, wind power and solar power

Why the need to manage sustainable resources

helps to protect natural resources so we don't run out

Evaporation

liquid to water vapor

Condensation

The change of state from a gas to a liquid

Precipitation

rain, snow, sleet, or hail that falls to the ground.

Transpiration

Evaporation of water from the leaves of a plant

Interception

Water being prevented from reaching the surface by trees or grass

Infiltration

movement of water into soil

Surface runoff

liquid water runs on the surface

Through flow

water goes to the soil to rivers

Ground water flow

goes through cracks & spaces to lower underground

Ice flow

movement of ice crystals

Ocean circulation

movement below the surface, by atmospheric circulation

Major components of earth's atmosphere

Nitrogen, Oxygen, Carbon Dioxide, Argon, Water Vapour

Nitrogen

Most abundant gas in the atmosphere

Oxygen

O2 (g)

carbon dioxide

CO2

Argon

Ar

structure of the atmosphere in order

troposphere, stratosphere, mesosphere, thermosphere

Ecosystem

living and nonliving things in an area

Biome

biological communities in a shared area

Population

organisms of the same species in a particular area

Community

group of different population of species interacting in an area

Habitat

the place within an ecosystem where an organism lives

Niche

role of a species in a ecosystem

Biotic

living things (producers, consumers, decomposers, decomposers)

Abotic

nonliving (air, water, sunlight, soil, and temperature)

competition

the struggle between organisms to survive in a habitat with limited resources

grazing

act of feeding on plants

Predation

An interaction in which one organism kills another for food.

Producers

Autotrophs (they make their own food)

Herbivores

Consumers that eat only plants

Photosynthesis

plants synthesise glucose using carbon dioxide, water and energy from sunlight.

Photosynthesis equation

6CO2 + 6H2O --> C6H12O6 + 6O2 (carbon dioxide + water --> glucose + oxygen)

Chlorophyll

Green pigment in plants that absorbs light energy used to carry out photosynthesis

ozone layer

a layer in the stratosphere that contains a concentration of ozone sufficient to block most ultraviolet radiation from the sun

natural greenhouse effect

Heat buildup in the atmosphere due to the presence of 'greenhouse' gases like carbon dioxide, methane, and water vapor.

greenhouse gases

Gases such as carbon dioxide, methane, nitrous oxide, water vapor, and ozone in the atmosphere which are involved in the greenhouse effect.

water vapour

water in gas form h20

Carnivore

eat meat

omnivores

eat both plants and animals

Primary consumer

An organism that eats producers (herbivores)

Secondary consumer

Carnivore that eats herbivores.

tertiary consumer

An organism that eats secondary consumers

Decomposer

An organism that breaks down wastes and dead organisms

Tropic levels

feeding levels in a food chain

How is energy lost in a food chain?

Lost in the form of heat due to cellular respiration

aerobic respiration

the chemical reactions in cells that use oxygen to break down nutrient molecules to release energy

aerobic respiration equation

(glucose + oxygen -----> carbon dioxide + water + energy) C6H12O6 + 6 O2 > 6 CO2 + 6 H2) + energy

Respiration

Inhalation and exhalation of air.

Feeding

the act of supplying food and nourishment

fossilisation

process of preserving parts of organisms that lived in the geological past

Combustion

the process of burning something

independent variable

variable that is manipulated

dependent variable

The outcome factor

Theory

A hypothesis that has been tested with a significant amount of data

reliable

deserving trust, dependable

Bias

A particular preference or point of view that is personal, rather than scientific.

climate change unreliable data

limited data, lack of knowledge, uncertainty in climate models

random sampling

a method of poll selection that gives each person in a group the same chance of being selected
