Every deck we have for Ecology, part of AQA GCSE Biology. 134 questions written against the published specification, free to study with no account. Each deck schedules its own reviews, so cards you find hard come back sooner than ones you have already got right.
What organisms compete for, abiotic and biotic factors, structural behavioural and functional adaptations, extremophiles, and why communities depend on each other.
Levels of organisation from individual to ecosystem, food chains and predator prey cycles, and the required practical using quadrats and transects.
The water cycle and the carbon cycle, the role of decomposers, what affects the rate of decay, and how compost and biogas make use of it.
Why biodiversity matters, pollution of land water and air, deforestation and peat destruction, global warming and its effects, and programmes to protect species.
Trophic levels and pyramids of biomass, why so little biomass is transferred between levels, threats to food security, and sustainable farming and fishing. Biology only content.
Ecology is one topic of AQA GCSE Biology. The other topics are all covered too, in the same format.
