Bbc: Gcse Bitesize: 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.
Concord Consortium
Concord Consortium: Stem Resources: Photosynthesis
This activity introduces the concept of plant color being determined by pigments, which interactive with light. The idea that chlorophyll is used by plants for energy is then discussed, along with the first step of the photosynthetic...
Texas Instruments
Texas Instruments: Photosynthesis and Respiration
Students use the gas sensors to measure the amounts of oxygen and carbon dioxide consumed or produced by a plant during respiration and photosynthesis. They also determine the rate of respiration and photosynthesis in a plant.
