Write the following terms on the board: competition, predation, symbiosis, mutualism, commensalism, and parasitism. the deepest ocean zone, below 914 meters (3,000 feet). It is more important now than ever that we sustain healthy coral reefs to support these intricate relationships, communities, and ecosystems. In some cases, their relationship may turn into a mutualistic oneparticularly with cleaner shrimp. Scientists fit wild animals with a GPS tracker and a combination video and audio recorder with environmental data instruments to measure such things as depth, temperature, and accelerationwhich allow the study of animal behavior without interference by human observers. Therefore, making this relationship obligate mutualism, as mentioned before. Thats just the way the world works, I suppose? Use a National Geographic image to explore commensalism and discuss the origins of Crittercam.Display the image lemon shark in the resource carousel and have students observe it closely. 5. Ask groups to draw the L column of their chart and then discuss and write what they, based on students' written responses in the KWL charts, by using the provided answer key to check students' completed worksheets, Caribbean Cleaners (2.5 minutes)mutualism, Giving Fish a Bath (5.5 minutes)parasitism, Clownfish and Sea Anemone Partnership (1.5 minutes)mutualism, symbiosis: mutualism (both benefit); parasitism (one benefits/one harmed); commensalism (one benefits/one unharmed), trophic levels: producer (autotroph); primary/secondary/tertiary consumer (heterotroph); herbivore, carnivore, omnivore, decomposer, parasite, apex predator, use scientific terminology to describe the ecological principles occurring in a variety of marine ecosystems, infer that different marine ecosystems are characterized by the same ecological processes, including interdependence, niche selection, and adaptation, describe possible ecological relationships between species that live in close proximity to each other, define symbiotic relationships as mutualistic, parasitic, or commensalistic, describe specific ways in which species, populations, and communities of organisms are interdependent and interact with one another and with their environment, discuss ways in which humans interact with and impact marine ecosystems, describe the abiotic and biotic components of a marine ecosystem, list several marine organisms and explain their trophic relationships using a food web, describe the adaptations and niches of several marine organisms, predict the effects abiotic changes or trophic imbalances might have upon an ecosystem as a whole, Tech Setup: 1 computer per classroom, Projector, Speakers, the interactions between biotic and abiotic ecosystem components, ecological principles related to food webs, adaptations, niche selection, and symbioses, interactions between biotic and abiotic ecosystem components, ecological principles related to food webs, adaptations, niche selection, symbioses. The two species will interact or rely on each other for survival. The shrimp dig a decent sized burrow in the floor of the ocean, and the goby will then live in the entrance of that burrow. Another example of mutualism in the ocean is that between corals and zooxanthellae which is the photosynthetic algae that live within most types of coral polyps. Ask them to write down what they Want to know about the key terms. Interestingly, the boxer crab also shares a similar relationship with sea anemonesit feeds the anemone and, in exchange, makes use of its stinging tentacles as a defense mechanism or deterrent. In return, the clownfish rids the anemone of parasites, wards away predators, and even offers nutrients by way of its excrement. A popular example of mutualism in the ocean is the relationship between sea anemones and clownfishes. Parasitism- is when one species benefits (parasite) and the other is harmed (host). In 1986, a shark approached him during a dive near Belize. The porcelain crab is protected from any predator since most sea creatures will get stung by the anemone. One type of Mimicry is when one organism that is harmless evolves to look similar to another organism that is poisonous. In this educational video, you can see how the isopod parasites are removed from mud shrimp species in order to help them. Discuss the examples as a class. Introduce the activity using a KWL chart.Provide each student with a copy of the Marine Ecology Video Scavenger Hunt worksheet and divide them into groups of four. all the different kinds of living organisms within a given area. This affects the population and causes an imbalance in the ecosystem. The health of Maine lobsters is always top of mind, and is becoming even more tenuous as the climate warms and changes the dynamics of ocean ecosystems. An adaptation is passed from generation to generation. Ask: Other than the shark, are there any other organisms you see? Many various symbiotic relationships (involvement of two organisms) can be seen in the Arctic. The barnacle, on the other hand, reaps great rewards by attaching itself to a whale because of its filter-feeding nature. a modification of an organism or its parts that makes it more fit for existence. Instruct students to pay close attention to the ways in which species, populations, and communities of organisms are interdependent and interact with one another and with their environment. organism that can produce its own food and nutrients from chemicals in the atmosphere, usually through photosynthesis or chemosynthesis. Point out that the term symbiosis is an overarching term for mutualism, commensalism, and parasitism and that the ecological relationships predation and competition are not generally considered to be symbiotic. }, Every organism depends on living and non-living things to survive. But also remember that the bigger the network, the less any one species affects it. READ DIRECTIONS Activity 3: Create an Imaginary Marine Ecosystem 2 hrs Yes, they do look like tiny cheerleaders under the sea. . Ask students to orally explain why they labeled each mutualism, commensalism, or parasitism. The fish can be killed if there are too many fish lice attached to it. Indeed, even the Arctic has parasitism. Symbiosis in the Deep Sea - Woods Hole Oceanographic Institution Why is it important to identify and understand these relationships? When temperatures of the ocean rise, it can stress out the corals and release the algae from its protective home. A mutualism example in the ocean is the remora that latches onto the mantaray for protection, transport, and food scraps, and in return the mantaray receives a cleaning to stay free of parasites. National Geographic Headquarters The unusual N 2 -fixing unicellular cyanobacteria (UCYN-A)/haptophyte symbiosis has been found in an increasing number of unexpected environments, including northern waters of the Danish Straight and Bering and Chukchi Seas. They come in a variety of forms, such as parasitism (where one species benefits and the other is harmed) and commensalism (where one species benefits and the other is neither harmed nor helped).
