Marine food webs. Resource. Add to collection. Feeding relationships are often shown as simple food chains – in reality, these relationships are much more complex, and the term ‘food web’ more accurately shows the links between producers, consumers and decomposers. A food web diagram illustrates ‘what eats what’ in a particular habitat.
The next level of the marine food chain is made up of animals that feast on the sea's abundant plant life. On the ocean's surface waters, microscopic animals— zooplankton, which include jellyfish and the larval stages of some fish, barnacles, and mollusks—drift across the sea, grazing opportunistically. Larger herbivores include surgeonfish ...
Made of interconnected food chains, food webs help us understand how changes to ecosystems — say, removing a top predator or adding nutrients — affect many different species, both directly and indirectly. Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and ...
The purpose of this classroom video is to see examples of ways students describe differences between food webs and food chains in the ocean. For additional classroom context, video analysis, and reflection opportunities, read the Picture of Practice page for "Marine Food Webs" in the One Ocean Environmental Literacy Teacher Guide, page 59.
Food webs consist of different organism groupings called trophic levels. In this example of a coral reef, there are producers, consumers, and decomposers. Producers make up the first trophic level. A producer, or autotroph, is an organism that can produce its own energy and nutrients, usually through photosynthesis or chemosynthesis.
Aquatic food webs are complex groups of organisms that perform different functions in the ecosystem. Phytoplankton are small primary producers suspended in water. They use nutrients along with carbon dioxide to harness sunlight energy and create biomass through the process of photosynthesis. Phytoplankton biomass is usually the primary food for ...
Further explore marine habitats, marine food webs and Marine organisms and adaptations. Activity ideas. Try these similar activities: Making a food web is a practical way for students to understand the complexity of food webs. Marine ecosystem this interactive diagram explores food webs and other aspects of life in the sea.
A food chain shows how energy passes from one living thing to another. The great white shark is at the top of the ocean food chain. Read on to learn more. ILLUSTRATION BY DARBY MINTER FOR TIME FOR KIDS. 1.The Sun Light from the sun gives plants energy. 2. Seaweed This plant soaks up sunlight. 3. Fish Some fish eat plants to live.
Modeling Marine Food Webs and Human Impacts Overview In this two-part lesson, students will develop food webs and investigate human impacts on marine ecosystems. In Part I, students will explore the ecological role of organisms in an ocean habitat and use information provided on Food Web Cards to develop food chains. In Part ll, students will model
Summary. In this active game that illustrates the concepts of ecological balance, interdependence, and trophic energy transfer in marine food webs, students play the roles of organisms that are representative of the different aquatic trophic levels. The game can be played using various environmental conditions and manipulations of organism ...
Let's learn about marine food chains In this STEM and Beyond video we will learn all about what food chains are and which food chains we find in the sea. We ...
Students will investigate the food web and trophic levels of a specific marine habitat in the Gulf of Maine. Using data gathered in VES-V, students will compare the biomass of a predator (Atlantic cod) with one of its prey (Atlantic herring). Based on this data, students will infer a relationship between the trophic level and biomass of a type ...
The large predators that sit at the top, or apex, of the marine food chain are a varied group. They include finned animals, such as sharks, tuna, and dolphins; feathered animals, like pelicans and penguins; and flippered ones, like seals and walruses. These apex predators tend to be large, fast, and very good at catching prey.
Most marine species are part of a food chain. A food chain is a top-to-bottom set of animals and plants. They are connected to each other because those on top eat those below. These food chains come together to form a food web. The bottom level of the ocean's food chain is made up of tiny living things.
The next level of the marine food chain is made up of animals that feast on the sea's abundant plant life. On the ocean's surface waters, microscopic animals—zooplankton, which include jellyfish ...
Grades 3-5: 5-LS2-1 - Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment. In this lesson students make a model, marine food web. 5-PS3-1 - Use models to describe that energy in animals' food (used for body repair, growth, motion, and to maintain body warmth) was once energy from the sun.
Marine Food Chain Lesson for Kids. Instructor Mary Grace Miller. Mary Grace has taught first grade for 8 years and ESL for 8 years. She has a Bachelor's degree in Elementary Education, holds ...
Marine Food Pyramid. This food pyramid displays a basic marine food web. Organisms on the first trophic level, such as plants and algae, are consumed by organisms on the second trophic level, such as conchs and blue tangs. At the top of the food web is an apex predator, a shark. Illustration by Tim Gunther.

Directions. 1. Define the role of marine microbes. Explain to students that, in a single drop of salt water, thousands of microbes (tiny organisms), including bacteria and phytoplankton (tiny floating plants), are interacting to form the base of the food web for the entire ocean.
