The benthic zone teems with life and biodiversity and acts like the digestive system of the pond. This video explains how organisms here have adapted to living in conditions of low light and low oxygen and why they are crucial for processes of nutrient cycling and maintaining water quality. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students. Show Less

The euphotic and profundal zones, which together comprise the limnetic zone, are home to a variety of organisms. This video looks at the characteristics of primary producers and consumers and how energy is transferred and lost through the different levels in a food chain. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students. Show Less

The organisms found in the littoral zone are critical for the biological cycling of abiotic factors. This video explores the complex relationships between primary producers, lower level consumers and higher order consumers and how they can be modelled using food chains and food webs. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students. Show Less

The plants found in the littoral zone play an important role in maintaining and supporting the biotic and abiotic conditions of a healthy pond. This video explains how these plants photosynthesise, looking at the role reeds and rushes play in transforming sunlight into energy that flows through the ecosystem. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students. Show Less

A pond is an ideal place to see how living and non-living things interact with each other and their environment. This video introduces key aspects of pond ecosystems, explaining how abiotic factors define the four pond zones and how relationships between organisms can be modelled with food chains and food webs. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students. Show Less

The terrestrial zone is the area of land around the pond that is not regularly inundated with water. This video looks at biotic and abiotic factors in the terrestrial zone, discussing the flora and fauna found in this zone and the potential impact human activity can have on the whole pond. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students. Show Less
