Unit 4: The Natural Environment and Species Survival
3.3 and 7.3 Topic 5: On the wild side
Explain that the numbers and distribution of organisms in a habitat are controlled by biotic and abiotic factors.
Describe how to carry out a study on the ecology of a habitat to produce valid and reliable data (including the use of quadrats and transects to assess abundance and distribution of organisms and the measurement of abiotic factors, e.g. solar energy input, climate, topography, oxygen availability and edaphic factors).

5.3.2 Populations and sustainability
There are many factors that determine the size of a population.
For economic, social and ethical reasons ecosystems may need to be carefully managed.
To support an increasing human population, we must try to use biological resources in a sustainable way.
Collection of quantitative data.
Presentation, analysis and evaluation of quantitative data.
Evaluation of data collection strategies.

G1.6 Outline the following interactions between species, giving two examples of each: competition, herbivory, predation, parasitism and mutualism
G1.7 Explain the principle of competitive exclusion
G1.8 Distinguish between fundamental and realised niches
Option G3: Impact of Humans on Ecosystems
G3.5 Discuss the impacts of alien species on ecosystems
Option G4: Conservation of Biodiversity
G4.1 Explain the use of biotic indices and indicator species in monitoring environmental change
Option G5: Population Ecology
G5.3 Describe one technique used to estimate the population size of an animal species based on a capture–mark–release–recapture method
