As a result of this lesson, upper elementary ocean explorers will be able to describe several interrelationships: symbiosis, mutualism, commensalism, and parasitism. They learn that the biological richness is increased near seamounts and use this type of community to find examples of each of these relationships. After discussion of these concepts, learners work in groups to research an individual seamount community member. They prepare reports to share with the rest of the class. 
Use background information and vocabulary to familiarize your students with the concept of symbiosis and the role agriculture plays in the shared relationship. They then write the vocabulary in their lab books or journals, and read the story, listing the symbiotic categories.
In this species relationships worksheet, students will brainstorm animals or plants that are examples of mutualism, commensalism, and parasitism.
In this trials for life worksheet, students fill in the charts as they watch a video. Students identify the types of symbiosis as mutualism, commensalism, parasitism, or predator-prey relationship.
Students explore the different interspecies relationships namely mutualistic, commensal and parasitic. In this ecology lesson, students investigate an ecosystem disrupted by humans. They formulate an action plan to save it and present their proposed solutions in class.
Offering a comprehensive overview of symbiotic relationships, this presentation would be a great way to introduce or review material covered in a biology class. There are definitions, examples, and a quiz on the meaning of parasitism, mutualism and commensalism. In the quiz, there are a few pictures that teachers may want to swap for better illustrations.
Three types of symbiosis are explained: parasitism, commensalism, and mutualism. This is done with colorful animation and lively dialogue in a straightforward and easy-to-follow manner. Have your ecology class watch this at home and then come to class to discuss the interactions between organisms. Then they can take the included multiple-choice quiz to assess their understanding.
The topic is symbiotic relationships, and in this case, we get to look at the relationship between the sea anemone and the hermit crab. They review log entries from a Northwestern Hawaiian Island expedition which occurred in 2002, paying close attention to the observations about hermit crabs and anemones. They discuss symbiosis and how two organisms can mutually benefit from living in close proximity. To assess student understanding the class prepares a role-play to summarize what they've learned.
Students gain skill in the design, implementation, and reporting of a scientific research project using the scientific method. They set up an experiment to determine the effect of adding the Rhizobium bacteria to one group of legume seeds. Students plant seeds in containers containing vermiculite and after the seeds germinate, they take the pots home to continue the project.
Is it a producer, carnivore, omnivore, scavenger, or decomposer? Different relationships among organisms are explored here. It is a simple, multiple choice assignment. Use it as a quick warm-up or quiz.
In this symbiosis activity, students will brainstorm 2 examples of each different type of symbiotic relationship which includes mutualism, parasitism, and commensalism.
In this symbiosis worksheet, students complete a graphic organizer about the three types of symbiosis. They define commensalism, mutualism, and parasitism and list the important things to remember about each.
Providing a sweeping overview of population and community interactions, this ecology instructional activity gets learners thinking. They differentiate between habitat and niche, describe and give exemplars of various animal and plant defenses, explain illustrations of ecological concepts, and more. This is an outstanding review of basic ecological concepts.
Pairs of ecologists select an animal and investigate an ecosystem from its point of view. This simple lesson involves Internet research and putting together a presentation of collected information. 
In this ecology worksheet, students will look at the relationships between the biotic and abiotic factors in an ecosystem. Students will use a diagram to answer questions about food chains, tropic levels, and biomass. Students will explore organism populations and their limiting factors. This worksheet has 5 true or false, 7 short answer, and 14 fill in the blank questions.
Someone set out to create an epic slide show on ecosystems, but seems to have stopped short. It begins by examining the parts of an ecosystem and roles that different organisms play within it. Simple, informative, and colorful, these slides are directed at upper elementary ecologists. The last half of these 87 slides; however, are void of photographs or graphics. They do have text about the biomes of the world. If you find the first half to be of your liking, all you would need to do is add some photos to make this slide show an excellent complement to your instruction.
In this symbiosis activity, students compare and contrast mutualism, commensalism, and parasitism. This activity has 6 matching, 1 fill in the blank, and 1 short answer question.
Students discuss how organisms relate to one another. They work together to research a specific organism and how it relates to other organisms. They present their findings to the class.
Learners investigate the interaction in an oceanic ecosystem. In this symbiotic relationship lesson, learners investigate how ecological relationships evolve over long periods of time in order to maintain balance and stability of the ecosystem. This lesson includes Quicktime video and a rubric.
Explore the different types of symbiotic relationships that exist between species. Your class will investigate how humans influence the evolution of bacteria through the development of antibiotics.
