Shore habitats
Surface film habitats
Open water habitats
Bottom water habitats

Discuss the different organisms found in a food web – producers, consumers, and decomposers. The producer level of a pond's food web collectively includes the many species of floating and rooted aquatic plant life that absorb items such as sunlight, water, air and soil minerals. The primary consumers in a pond's food web consist of tiny herbivorous animals that feed on algae and other aquatic plants to sustain themselves. They also include a variety of nearly microscopic animals collectively known as zooplankton. This second level of animal consumers includes many species of fish, frogs, other amphibians, crayfish and reptiles such as turtles and water snakes. Each living thing in an ecosystem is part of multiple food chains. Learn how living things interact in the Early Bird Food Webs series. When there are too many animals in a population, food may become scarce and some animals may die of starvation or move. Causes of Change Some changes affect other organisms. What would happen to a pond ecosystem if the decomposers died? Creating a food web is a really great way to learn more about how organisms and animals live in their natural habitats.

Scavengers And Decomposers In A Wetland What Are the Decomposers in the Underwater Ecosystem. 3 The plants provide food for many creatures. They are the last step in the food chain, which recycles nutrients and breaks down wastes and organic matter in the ecosystem. The recycling of nutrients by decomposers make the nutrients available to new generations of plants that are eaten by tiny animals, which are eaten by larger animals, which are eaten by the largest animals. Pond Water Pond Water WebWebWeb –––– Lesson Plan Lesson Plan Lesson Plan Purpose: As a result of this lesson, students will become familiar with common organisms found in a pond and discover their importance in a balanced aquatic habitat as they create food webs. Decomposers include certain types of bacteria, worms, slugs, snails and fungi. Opportunistic decomposers include hagfish, fiddler crabs, sea urchins, sea stars and sea cucumbers. While the terms decomposer and detritivore are … While a food chain shows how ecosystems function in a linear way, a food web is a more visual approach with multiple animals connected to one another.

Organize a set of organisms into a food chain 3. Freshwater producers use sunlight and carbon dioxide to perform photosynthesis and serve as a food source for consumers in the ecosystem. bottom of the pond. Producers include microscopic, floating plant life collectively known as algae and larger rooted water plants.

For example, an owl eats many types of rodents, including rats, voles, shrews and birds.

This third level of animal consumer includes fish- and frog-eating water birds, fish-eating hawks, numerous small mammals and human beings. Decomposers are life forms that break down dead plants and animals so that the nutrients are released back into the water and air, where they become available to plants. Generally, the decomposers either live in the soil layer beneath water or in the mud. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem. Discuss with students that there is another important component to our food chain. 2 Pond Plants Algae Duckweed Elodea Cattails Water lily .
