Population Ecology explores patterns in population growth, gives reasons populations grow and stop growing, and reveals trends in human population.

Animated graphs and diagrams vividly depict core population concepts including: the lag phase, exponential growth, J curve, dynamic equilibrium, and carrying capacity. Challenging “hands-on” tutorials consist of spelling the correct word after reviewing a clue, correctly labelling diagrams and graphs, clicking on a term that correctly describes a picture, and more.

Topics covered in this program include: Defining a Population; Characteristics of Populations; Types of Populations; Growth Rate of Populations; Strategies of Reproduction; Human Population Growth; Limiting Factors; Age Structure of Populations; and Interactions between Populations including endangered species.

Food Webs - Wins Single User Shipped in 7 days Cat.# MSE-1 $240.00 BUY

This model with mice, owls, foxes, rabbits and plants shows how populations are related in a food web; it also illustrates how the changes in population are unpredictable! To suit different age groups, you can focus on two and up to five species. Show results on a bar gauge, a results table or a time graph. Here is a tool for a simple or detailed investigation.

Students will learn:

• That a population is affected by sunlight, predation and competition;
• the units of biomass and population; populations are interdependent and changes are often cyclic;
• the number of predators affects the number of prey, even to the point that either dies out;
• that models simplify and help us to understand complex situations.

Teachers can:

• Examine cyclic changes in a food web: show the class the food web screen. Assign each student one organism to watch and note its population size on paper. Advance the web one year at a time for ten years.
• Ask each student to say what happened to his or her organism. Verify this on the graph screen. Repeat with the sunlight at maximum. Discuss why numbers rise and fall. Consider interdependence: let students run a model showing just rabbits and plants. Set the sunlight high.
• Predict the progress of two line graphs that will appear and then run the model. Restart the model, but this time add a fox population. Again ask students to predict the results and then run the model. Did the web sustain the foxes? What does the fox population depend upon?
• Investigate – see what happens in a food web where after years of happy coexistence, a disease affects the mice and they die out.

Students discover that each organism has a particular role (producer, consumer, decomposer) and niche in their environment. Students also learn about factors that limit populations and ways organisms have developed relationships of interaction that affect their survival.

Learners will:

• be able to match various levels of biological organization (species, population, community, ecosystem) to their descriptions.
• identify the role of producers, consumers and decomposers in an ecosystem.
• be able to match the terms habitat and niche to their description or definition.
• distinguish between examples of abiotic and biotic factors in an ecosystem.
• distinguish between examples of competition, symbiosis, and predation in communities.
• distinguish between examples of population size, spacing, and density.
• distinguish between different types of symbioses (commensualism, mutualism, or parasitism).
• predict the effect of changing certain limiting factors on carrying capacity, population growth/decline, or survival.

Pictures, sound and text covering aspects of life and living processes associated with the world's major habitats. They help to provide some understanding of the wide variety of living things and the way these survive and compete for resources. Choosing pictures from different modules allows comparisons to be made. They can be used to illustrate the existence of food chains and food webs and feeding at different trophic levels. They provide an elementary understanding of biomass, predator-prey relationships, and population pyramids in different ecosystems. They also give an appreciation of the role of decomposers in the cycling of nutrients and transfer of energy. 

The resources raise important issues such as the impact of human activities on environmental systems, the occurrence and effects of natural hazards and the need for management and conservation of fragile habitats.

• Alpine Habitats
• Desert Habitats
• Mediterranean Habitats
• Rain Forest Habitats
• Tropical Mountain Habitats
• Savannah Habitats
• Polar Habitats
• Temperate Forest Habitats

The interactive Courseware included takes the user through a progressive, structured and differentiated sequence of work directly related to the National Curriculum. The course is extensive and caters for different levels of ability. The questions are put in many formats from simple multiple choice, multiple answer to cloze questions and pictorial choices, maximising interest and stimulating thoughtful responses. The results of all work are recorded for the user and the teacher. (Apple version requires Internet Explorer 5 or above).

Pictures, sound and text covering aspects of life and living processes associated with arrange of distinctive habitats in the UK. They help to provide some understanding of the wide variety of living things and the way they survive and compete for resources. Choosing pictures from different modules allows comparisons to be made. The materials can be used to illustrate the existence of food chains and food webs and feeding at different trophic levels. They provide an elementary understanding of biomass, predator-prey relationships, and population pyramids in different ecosystems. They also give an appreciation of the role of decomposers in the cycling of nutrients and transfer of energy. 

It is possible to use these resources to raise important issues such as the impact of human activities on environmental systems, the occurrence and effects of natural hazards and the need for management and conservation of fragile habitats.
