The Terrestrial Zone

The Pond: Community Ecology in Action

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...Show More

The Littoral Zone: Food Chains and Food Webs

The Pond: Community Ecology in Action

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...Show More

The Limnetic Zone

The Pond: Community Ecology in Action

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...Show More

The Benthic Zone

The Pond: Community Ecology in Action

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...Show More

The Littoral Zone: Photosynthesis

The Pond: Community Ecology in Action

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...Show More

The Still Water Pond

The Pond: Community Ecology in Action

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...Show More
Photosynthesis

Photosynthesis

Life in the Sea

Photosynthesis supplies all oxygen for life, and it began in the sea. Amazingly, it all relies on one basic kind of chemical reaction that was achieved over two billion years ago by cyanobacteria, and cyanobacteria living as endosymbionts in...Show More
Coordination and Control 2: Plants

Coordination and Control 2: Plants

Coordination and Control

This program aims to give students a better understanding of the complex interaction between organism and environmental stimuli. It deals with how plants use hormones to coordinate and control their activities with changes in the environment.
In Focus: Plants, Light and Water (Senior Version)

In Focus: Plants, Light and Water (Senior Version)

This programme looks at two naturally occurring phenomena that are essential to the survival of plants, light and water. It covers photosynthesis and cellular respiration, and compares the products and reactants, and other characteristics of each...Show More
In Focus: Introduction to Plants (Junior Version)

In Focus: Introduction to Plants (Junior Version)

This programme examines the form and functioning of plants. It looks at the characteristics of all living things, including cellular respiration, photosynthesis, growing and repairing, responding to stimuli, taking nutrients from the environment,...Show More
Mechanisms of Evolution

Mechanisms of Evolution

Evolution is the gradual change that can be seen in a population’s genetic composition, from one generation to the next. The three main mechanisms of evolution include genetic drift, mutation and natural selection. The first part concentrates...Show More
In Focus: Introduction to Plants (Senior Version)

In Focus: Introduction to Plants (Senior Version)

This programme is an introduction to botany for senior secondary students. It explores the remarkable world of plants - without them, no other life form would exist. It looks at characteristics of all living things, including cellular...Show More
Plant Adaptations

Plant Adaptations

This programme investigates the basic characteristics of aquatic and terrestrial environments, and the adaptations of the plants that live in those environments. Among the specific areas examined are: - Supporting structures and movement,...Show More
