AQA A-Level Environmental Science 3.6 Sustainability and research methods overview quiz quiz

Meeting present needs without compromising future generations' ability to meet theirs

Using up all available natural resources as quickly as possible to benefit only the present

Banning all use of natural resources completely so none are ever extracted

Maximising economic growth regardless of the environment

The total number of different species living within a particular habitat

The area of land and sea needed to supply resources and absorb waste

The maximum population that an area is able to support over time

The combined total mass of all living organisms in an ecosystem

The total quantity of natural resources that a single person consumes in a year

The combined weight of all the waste produced by a population over its lifetime

The maximum population an environment can support indefinitely

The rate at which a depleted resource naturally renews itself

Strictly within their natural renewal rate so stocks always recover fully

Only during the hours of daylight rather than continuously

By recycling them after every single use

Faster than they can be replenished

Mark-release-recapture

A single quadrat

Measuring soil pH

A line transect of plants

To save time by sampling only the most convenient corner of the habitat

To avoid bias and give a representative estimate

To deliberately locate and record the very densest patch of plants present

To keep the equipment dry by steering clear of any wet or boggy ground

The number of fish species present

The abundance of algae

Dissolved oxygen concentration

The presence of indicator species

The individual values are widely spread out on either side of the mean

The calculated mean must have been worked out incorrectly somewhere

There are only a very small number of measurements in the data set

The values are tightly clustered around the mean

There is an association, but it does not prove causation

One variable must definitely be the direct cause of changes in the other

The two variables are entirely unrelated to one another in any way

The data collected must be invalid and should be discarded entirely

The most attractive way to present the collected data in a graph

Whether a result is significant or could be due to chance

Which particular species of animals ought to be sampled in the field

The total financial cost of carrying out the whole investigation

Reliability is measuring the right thing, whereas validity is simply the repeatability of the results obtained

They are different words that ultimately mean exactly the same thing in scientific investigation

Reliability is repeatability; validity is measuring what is intended under controlled conditions

Reliability applies only to graphical work, while validity applies only to results shown in tables

The total number of birds living across an entire country at one time

The pH of one single soil sample taken from a fixed point

The overall economic value of the timber in a managed forest

How a community changes along an environmental gradient
