Description

Travel through time and space with Dogtor Woof to unravel the mysteries of nature! You will join Dogtor Woof as they explore a forest and its inhabitants. Each of them takes a unique role in a Food Web. Experience the world through the eyes of five different organisms with unique special abilities to find out how Food Webs work!

Instructions

Play through this interactive game to learn about Food Webs in an Ecosystem. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

The cycling of matter can be modeled in the decomposition of biomass in a compost bin.

Tertiary consumers are usually at the top of the food chain and consume secondary and primary consumers.

Primary consumers eat plants and are known are herbivores.

Photosynthesizing organisms are the foundation of virtually all food webs.

In the nitrogen cycle, nitrogen flows between living systems and Earth's atmosphere.

In a trophic pyramid, about 10 percent of the energy at one trophic level is passed on to the next level.

Food webs can show the flow of energy through a terrestrial ecosystem.

Food webs can show the flow of energy through a marine ecosystem.

Food webs can show the flow of energy through a freshwater ecosystem.

Decomposers break down dead or decaying organisms and return nutrients to soil.

Autotrophs, also known as producers, are organisms that can produce their own energy from the Sun through photosynthesis.

A trophic level is the feeding position of organisms in a food chain.

A food web is a diagram that shows the different paths along which energy can flow through through an ecosystem.

A food chain is a diagram showing a single path along which energy can flow through an ecosystem.

Biomass is organic material from plants or animals.

The primary source of energy on Earth's surface is sunlight.

Carbon cycles through living systems through the processes of photosynthesis, cellular respiration, and decomposition.

Secondary consumers are usually smaller carnivores and omnivores that eat primary consumers.

Trophic pyramids show how energy is passed from lower to higher trophic levels in a food chain or food web.

Heterotrophs, also known as consumers, must consume other organisms in order to obtain energy.

There are generally fewer organisms at higher trophic levels because only a small fraction of matter and energy is transferred from lower levels.

Discussion Questions

Before the Game

What is the source of all energy in an ecosystem? What is the relationship between matter and energy? Why are plants categorized as autotrophs?

After the Game

What compounds from the soil and air did the plant need to grow? What is the difference between autotrophs and heterotrophs? How do both autotrophs and heterotrophs work together to transfer energy in an ecosystem? How do food webs show the flow of energy throughout an ecosystem? How do omnivores function in a food web?
