[Free Registration/Login may be required to access all resource tools.] Based upon the way organisms acquire their energy students will understand how to group them as consumers, decomposers or producers.

Students learn about Abiotic and Biotic Factors and how they affect the ecosystem in which an animal might live in.

A video and a short multiple-choice quiz on the topic of ecosystems, covering biotic and abiotic factors, and the roles organisms play in an ecosystem.

Learn how scientists classify different types of organisms in an ecosystem or in a food chain by their role and function as either a producer, a consumer, or a decomposer. Then play a game that tests your understanding of these important...

This lesson focuses on food chains in ecosystems, including levels of consumers, decomposers, and a list of common words used with food chains and their definitions. It also provides a link to an assessment.

This lesson focuses on the organization of an ecosystem. The feeding relationships between organisms in an ecosystem can be seen in food chains. Sampling allows us to measure the abundance and distribution of these species. It provides...

Being field scientists, students will explore a wooded area in their community and journal about their observations. Students will collect information about producers, consumers, and decomposers in the ecosystem. They will then construct...

A video and a short multiple-choice quiz on the nitrogen cycle and how it works in an ecosystem.

A video and a short multiple-choice quiz on food webs that explains the difference between food webs and food chains, and the relationships that exist between organisms.

A video and a short multiple-choice quiz on food chains that explains how energy flows through the chain, beginning with plants.

Explore the food web in a coral reef with these illustration. Identify the consumers, producers, and decomposers that are located within this ecosystem. Site includes illustration exploring the different food chains as well as questions...

This lesson focuses on the carbon cycle which shows how atoms of carbon can exist within different compounds at different times and be recycled between living organisms and the environment. It also provides a link to an assessment.

A lesson plan outlining activities for a science unit where students can learn about the relationships and the flow of energy within an ecosystem. These include predator and prey, hosts and parasites, and consumers, producers, and...

Starts with living and non living and works through producers, consumers, food chains and food webs.

Students explore the biosphere's environments and ecosystems, learning along the way about the plants, animals, resources and natural cycles of our planet. Over the course of lessons 2-6, students use their growing understanding of...

This interactive website explores the various soil layers and introduces you to the lifeforms that live in those soil layers.

[Free Registration/Login Required] This flipchart focuses on how plants and animals get energy and different habitats.

Learners will use a card sorting activity to construct a food chain and identify the role of organisms within that chain. The cards represent different individuals in an ecosystem and will help students begin to understand the concepts...

[Free Registration/Login may be required to access all resource tools.] Fungi are extremely important to the ecosystem because they are one of the major decomposers of organic material. But how do they help people? They are used to help...
