B2.4 Interdependence Flashcards
skin cancer
A tumour of the skin, usually caused by too much UV-B radiation.
nitrate
Chemicals used as fertilisers to make crops grow better.
phosphates
Chemicals that act as fertilisers which are also found in sewage.
pollution
Contamination of the environment.
adaptation
Changing to suit the environmental conditions.
resource
Material or energy used by living things.
environment
A particular set of conditions, including water, temperature, light and air.
biodiversity
A variety of species of plants and animals.
population
A group of individuals of the same species living in the same habitat.
conservation
Keeping a habitat the same as environmental conditions change.
environmental factors
The living and non-living factors which affect organisms.
aquatic
Living in water.
competition
The battle between different types of organism over the same resource.
global temperature
Average temperatures measured across the whole surface of the planet.
living indicator
Evidence of the effects of human activity on the environment shown on a live organism.
interdependence
The mutual dependence of one organism with another.
terrestrial
Living on land.
replacement planting
Replacing a tree or shrub by planting another of the same species.
ozone
A gas found in the upper atmosphere.
sewage
Solid waste from humans and other animals.
succession
The gradual change of a habitat to become woodland.

Living creatures such as animals, plants or insects.
predation
Killing and eating other animals for food.
reforestation
Replanting trees to increase the number of trees.
coppicing
Cutting trees and shrubs to ground level to encourage rapid new growth.
recycling
Reusing materials instead of the original resource.
extreme environment
Conditions that are far outside the boundaries where humans can live comfortably.
eutrophication
The process where fertilisers and sewage build up in water, over-encouraging algal growth which leads to light and oxygen supplies being depleted. This in turn leads to other organisms in the water dying off.
