Simple ecosystem diagram

This is a colour graphic representing the energy and nutrient flow in a simple food chain. The Sun and organisms making up the food chain are represented in diagrammatic form. The graphic is labelled and a key to the colour-coding of energy and nutrient flows is included.

Marine trophic pyramid

This image displays a type of diagram known as a trophic (or ecological) pyramid. This example depicts the organisms and the matter and energy flows in a typical marine ecosystem. The diagram shows six levels of organisms from primary producers through to the top carnivores, arranged in a pyramid. Also represented is the ...

Tuna sandwich trophic pyramid

This image is a diagram known as a trophic pyramid. This example shows the levels of an ecosystem that support the growth of tuna, which might be consumed by a human in a tuna sandwich. The diagram shows six levels in the 'pyramid' from phytoplankton through to humans, and visually depicts the size of the biomass at each ...

Interactive Resource

The virtual ecosystem

This interactive learning activity consists of a virtual ecosystem model that introduces the idea that all living things compete for food. Students can complete two game-like experiments to investigate the need an individual rabbit has for grass and then compare the needs of an individual rabbit to the needs of a population ...

Interactive Resource

Experiment with ecosystems

This interactive learning activity consists of a series of virtual ecosystem models for exploring the interrelationships within food webs. Students can complete two experiments to test hypotheses about producer-consumer and predator-prey relationships. The activity is supported by a 'Lab book' in which students can view ...

Collection

Teaching ideas: ecosystems

This collection, containing 26 digital curriculum resources, allows students to explore aspects of the flow of energy and matter in ecosystems. The resources comprise teaching sequences, units, worksheets, videos, podcasts and a card game. A variety of contexts is provided to allow students to investigate relationships ...

Cockles' role in food webs

This is a colour video clip of marine scientist Stephen Wing, from the University of Otago in New Zealand, discussing the role cockles ('Austrovenus stutchburyi') play in marine food webs in New Zealand. (Classification - Phylum: Mollusca; Class: Bivalvia; Order: Veneroida; Family Veneridae.)

Understanding food webs

This is a colour video clip in which ecologist Associate Professor Stephen Wing of the University of Otago talks about the importance of understanding food webs, particularly in marine ecosystems. He gives examples of how such understanding has been applied in Fiordland, New Zealand. Still images shown include marine organisms, ...

Interactive Resource

Antarctic food web game

This interactive resource provides an opportunity for students to construct an Antarctic food web. Students consider general information about the nature of food chains, food webs and energy flow and apply this to an Antarctic ecosystem. Specific information for seven Antarctic organisms is provided in a trophic table and ...

Photosynthesis and respiration: collection

This is a collection of 35 digital curriculum resources that explores the flow of energy and matter in an ecosystem. The collection comprises 25 images and 10 interactive simulations that highlight the processes of photosynthesis and respiration. Students can explore topics such as the transport of carbon through a plant ...

Collection

Decomposers and scavengers

This is a collection of 15 digital curriculum resources about the flow of energy and matter in an ecosystem. The collection comprises 12 images and 3 videos. Images identify a range of decomposers and scavengers, including soil invertebrates and fungi, found in various ecosystems and illustrate how organisms scavenge for ...

Collection

Producers

This is a collection of 15 digital curriculum resources about the flow of energy and matter in ecosystems. The collection comprises 13 images and 2 videos. Images identify producers found in various ecosystems and illustrate how typical terrestrial plants use sunlight to produce their own food. Other images show less familiar ...

Collection

Marine ecosystems

This is a collection of 25 digital curriculum resources about the flow of energy and matter in marine ecosystems. The collection comprises 19 images and 6 videos. Images allow students to identify a range of marine producers and consumers and to construct food webs. Some resources show the results of human activity on some ...

Photosynthesis and respiration: teacher resource

This teacher resource provides a range of possible activities that cover aspects of the science continuum for the flow of energy and flow of matter in an ecosystem. This teaching resource provides a range of classroom activities that explore the concept of the flow of energy and flow of matter in an ecosystem, specifically ...

Teacher resource

Photosynthesis and respiration: learning sequence

This learning sequence introduces photosynthesis and respiration. Students explore the roles of photosynthesis and respiration. They compare the differences between these two processes. They explain how energy moves through an ecosystem and some implications of the carbon cycle.

Science inquiry approach: learning strategy

This professional learning resource provides an overview of the inquiry approach to teaching science. It provides a 'bigger picture' context for the Digital curriculum resources in science project, particularly in relation to the rationale of the Australian Curriculum. The science inquiry approach - as it relates to the ...

Interactive Resource

Marine ecosystem

This is an interactive diagram of a New Zealand marine ecosystem. Selecting labels brings up a small screen with text and an image or a video. The interactive examines a simplified marine food web looking at the most significant components.

Interactive Resource

Predators and prey

This interactive learning activity consists of a virtual ecosystem model for exploring the selective advantage that coat colour can give to rabbits, and the significance of this to predator-prey relationships. Students can complete two experiments to investigate predator-prey relationships. The activity is supported by ...
