Adaptations, interdependence and competition - AQA
The abundance and distribution of organisms in an ecosystem is determined by biotic and abiotic factors. Animals and plants have adaptations to allow them to compete for resources.
Organisation of an ecosystem - AQA
The feeding relationships between organisms in an ecosystem can be seen in food chains. Sampling allows us to measure the abundance and distribution of these species.
Biodiversity and the effect of human interaction on ecosystems - AQA
Biodiversity is a measure of how many different species live in an ecosystem. Human activities like changing land use, deforestation and peat bog destruction reduce this.
