This is a PowerPoint presentation which covers the following areas as part of AQA A Level Biology 3.7.4 Populations in Ecosystems: The size of a population can be estimated using: • randomly placed quadrats, or quadrats along a belt transect, for slow-moving or non-motile organisms • the mark-release-recapture method for motile organisms. The assumptions made when using the mark-release-recapture method. This resource is designed to be delivered in a lecture style. This resource is a PowerPoint only.

This is a PowerPoint presentation which covers the following areas as part of AQA A Level Biology 3.7.4 Populations in Ecosystems: Populations of different species form a community. A community and the non-living components of its environment together form an ecosystem. Ecosystems can range in size from the very small to the very large. Within a habitat, a species occupies a niche governed by adaptation to both abiotic and biotic conditions. An ecosystem supports a certain size of population of a species, called the carrying capacity. This population size can vary as a result of: • the effect of abiotic factors • interactions between organisms: interspecific and intraspecific competition and predation. This resource is designed to be delivered in a lecture style. This resource is a PowerPoint only. This resource contains information relevant to older specifications and can be adapted accordingly based on your cohort of students
