HideShow resource information
Definition of a species
A group of organisms that can breed together to produce fertile offspring .
1 of 24
Growing single crops in large fields.
Definition of Monoculture
2 of 24
Definition of an Adaptation
A feature of a living organism that allows it to survive in their environment.
3 of 24
Phytoplankton to measure ocean temperature changes
Microscopic water plant that is used to measure climate change.
4 of 24
Animals which need lots of oxygen that are used to measure climate change.
Mayfly nymphs to measure oxygen levels in water.
5 of 24
Lichens to measure air pollution levels.
Plants sensitive to air pollution which are used to monitor climate change.
6 of 24
The definition of Sustainability
Meeting the needs of today without jeopardising the needs of the future.
7 of 24
Using the similarities and differences between living things to put them into groups.
The definition of Classification
8 of 24
The definition of Biodegradeable
Can be broken down by microorganisms.
9 of 24
-Changes in the climate that species cannot adapt to. -A new species competing with the existing ones in a habitat or causing diseases that can harm the existing species. -Another species in its food web becoming extinct.
Causes of the increasing extinction rates.
10 of 24
Reasons that new species develop.
-Mutations - Isolation of a group within a species which are then forced to adapt in order to survive. - Natural selection (survival of the fittest). -Environmental changes can lead to natural selection.
11 of 24
The process by which a species changes over time.
Definition of evolution.
12 of 24
Are evidence for evolution.
Fossils, DNA.
13 of 24
A place where an organism lives.
Definition of a habitat
14 of 24
Definition of extinction.
When all members of a species die out.
15 of 24
The difference between local and mass extinction.
Local: all the members of a species in an area die out. Mass: all the members of a species in the world die out.
16 of 24
Combustion. Respiration. Photosynthesis. Decomposing
The 4 processes of the carbon cycle.
17 of 24
The 4 processes of the Nitrogen cycle.
Nitrogen fixation. Denitrification. Excretion. Decay by bacteria and fungi.
18 of 24
When a gene is being copied and mistakes are made.
The definition of Genetic variation.
19 of 24
Reasons for biodiversity
Wild crops are used for developing new crops. Plant substances are used in creating medicines. It gives a species a greater chance for survival and allows for adaptation and the development of natural immunity to certain diseases.
20 of 24
Darwin & Lamarck
The two scientists with different theories about change in species
21 of 24
The definition of Natural Selection
When new species develop when their environment changes.
22 of 24
-Used for life processes(MRS GREN).-Escapes to the surroundings as heat. -Is excreted as waste. - Cannot be eaten.
What 4 things happen to energy in a food chain that is not passed on.
23 of 24
The process of changing the features of a species.
Selective breeding.
