Cards

Term

System

[image]

Definition
A system is: an assemblage of parts, their relationship forming a whole.
Composed by a number of interconnected parts. Vary in size, level and complexity. Organised in a hierarchy of systems and sub-systems.
Term

Open System

[image]

Definition
Exchanges matter and energy across it’s boundary with the environment – almost all systems are open.
Term

Climate Change

[image]

Definition
Global warming is the long-term rise in the average temperature of the Earth's climate system. It is a major aspect of climate change, and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming. 
Term

Biodegradable

[image]

Definition
(of a substance or object) capable of being decomposed by bacteria or other living organisms.
Term

Isolated System

[image]

Definition
where neither matter nor energy is exchanged between the system and the environment – it cannot exist naturally.
Term

Food Chains

[image]

Definition
illustrate direct feeding relationships between one organism and another in a single hierarchy. We are limited in the case of organisms that feed at multiple trophic levels. Helpful for analyzing aspects of an ecosystem function such as the response to pollutants.
Term

Species

[image]

Definition
A particular type of organism which can interbreed producing fertile offspring
Term

Population

[image]

Definition
group of organisms of the same species living together and capable of interbreeding.
Term

Habitat

[image]

Definition
Place where an organism or a biological population normally lives or occurs.
Term

Ecosystem

[image]

Definition
A community of interdependent organisms and the physical/ chemical (abiotic) environment which they inhabit.
Term

Trophic Level

[image]

Definition
The position an organism holds in a food chain in a given community.
Term

Parasitism

[image]

Definition
Where one species lives inside another and kills
Term

Diversity

[image]

Definition
Is the variation of living life form in a given ecosystem, biome or entire Earth. It is used as an indicator of the health of a biological system.
Term

Biodiversity

[image]

Definition
The amount of biological of living diversity that is located in a given area.
Term

Pollution

[image]

Definition
Is the addition of a harmful substance (heat) to the environment by human activity at a greater rate by which it can be rendered harmless.
Term

Natural Capital

[image]

Definition
all the resources which are given to is by nature – can be products as well as services – all of which can be described as such if well managed. The structure and diversity of the system are important components.
Term

Renewable

[image]

Definition
Living species and ecosystems which are self-producing and self-maintaining – their yield can be used as marketable goods.
Term

Non-Renewable

[image]

Definition
Are those that will eventually run out such as fossil fuels or metal ores.
Term

Sustainability

[image]

Definition
It the revenue generated by the natural capital, not living of the capital but the income. How much is made by the capital.
Term

Positive Feedback

[image]

Definition
Increases, any change away from the equilibrium are increased.
Term

Niche

[image]

Definition
The role a species plays in an ecosystem.
Term

Community

[image]

Definition
A group of populations living and interacting with each other in a common habitat (the biotic components)
Term

Mutualism

[image]

Definition
An interaction in which both species benefit.
Term

Biome

[image]

Definition
A collection of ecosystem sharing the similar climatic conditions
Term

Astronomy

 

[image]

Definition
  1. the branch of science which deals with celestial objects, space, and the physical universe as a whole.
Term

Veganism

[image]

Definition
 a lifestyle that excludes all animal products and attempts to limit the exploitation of animals as much as possible
Term

Smog

[image]

Definition
The term now used for any haziness in the atmosphere caused by air pollutants. Photo chemical smog is produced through the effect of ultraviolet light on the products of internal combustion engines. It may contain ozone and is damaging to the human respiratory system and eyes.
Term

Wind power 

[image]

Definition
use of wind to provide the mechanical power through wind turbines to turn electric generators and traditionally to do other work, like milling or pumping
Term

Typhoon 

[image]

Definition
A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere.
Term

Stratosphere

[image]

Definition
The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere
Term

Mesosphere 

[image]

Definition

 

the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.

Term

Thermosphere 

[image]

Definition
the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium
Term

Exosphere

[image]

Definition
the outermost region of a planet's atmosphere
Term

Paleontology 

[image]

Definition
Paleontology, sometimes spelled palaeontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene Epoch. 
Term

The Big Bang theory 

[image]

Definition
cosmological model for the observable universe from the earliest known periods through its subsequent large-scale evolution.
Term

Biosphere

[image]

Definition
That part of the Earth inhabited by organisms, that is, the narrow zone (a few kilometres in thickness) in which plants and animals exist. It extends from the upper part of the atmosphere (where birds, insects and wind- blown pollen may be found) down to the deepest part of the Earth's crust to which living organisms venture.
Term

Entropy

[image]

Definition

The measure of disorder or chaos. In isolated systems entropy tends to increase spontaneously

Term

 

Paleogene

[image]

Definition
oldest of the three stratigraphic divisions of the Cenozoic Era spanning the interval between 66 million and 23 million years ago
Term

Biotic Factors

[image]

Definition
A living, biological factor that may influence an organism or ecosystem; for example, predation, parasitism, disease, competition.
Term

Lithosphere

[image]

Definition
lithosphere is the rigid, outermost shell of a terrestrial-type planet, or natural satellite, that is defined by its rigid mechanical properties
Term
