Life In The Estuary — Science Learning Hub ~ UpdateNews

Food Webs in Estuaries. Green plants can change sunlight energy into food (chemical) energy. The sun is the ultimate source of energy for all living things. Producersmake their own food using energy from sunlight. This is called photosynthesis. algae eelgrass Microscopic phytoplankton. carbon dioxide waterStudents will apply knowledge of estuary organisms to explore food webs and energy flow in an estuary ecosystem using a food pyramid. Students will then read and discuss a scientific article about marine plankton food webs and climate change.The keystone species in this food web are the limpets. Only certain organisms can survive in estuaries due to high salinity (salt concentration in water) and constantly changing temperatures.Estuary food webs begin with the conversion of the sun's energy to food energy by plants and plankton. Simplified feeding relationships are shown in this diagram.There are two main feeding pathways. One begins with large plants such as mangroves, seagrass and rushes.Nutrients within the estuary are used by plants such as algae in the water, seagrasses, seaweeds and mangroves and they enter other parts of the food web when plants are grazed on by invertebrates. When the plants, or parts of them die, nutrients are re-cycled within the estuary by the actions of invertebrates and bacteria.

This estuarine food web shows how nutrients are transferred through ecosystems. For example, plants are consumed by invertebrates such as snails and cockles, which are then eaten by small fish, which in turn may be hunted by larger fish like snapper.Example of an estuary FOOD WEB SOURCE: Thinking, Created by Susana, This is an estuary, an estuary is where the ocean meets (2015), Fish Diet and Food webs in the Swan-Canning Estuary Marine plankton food webs and climate change. THREATS to estuary habitats Swan Canning Riverpark: Dolphin watch project.Food webs. Living organisms within an estuary co-exist in a network of interdependent feeding relationships, known as a food web. An estuarine food web contains the following elements: Phytoplankton. These microscopic organisms manufacture food by photosynthesis and absorb nutrients such as phosphorus and nitrogen from the water.Estuaries • are where fresh water from rivers meets and mingles with salt water from oceans • are among the most biologically productive ecosystems on Earth • are the source of a food web that begins with conversion of the sun's energy into food energy by marsh

impacts to phytoplankton and the estuary food web, little is known concerning how these changes will occur. Activity 4: Estuary Food Pyramid 4 Overview Students will use their understanding of five estuary organisms to explore food webs and the energy flow in an estuary ecosystem as shown in a food pyramid. These five organisms (or groups ofThe insecticide DDT, and the metal mercury, are known to progressively accumulate or build up in the tissues of organisms as they make their way from the bottom of the food web (algae, shrimp, oysters, fish) to the top (osprey, eagles, bears, people).Within the sediments, whether mud, sand or rocks, live billions of microscopic bacteria, a lower level of the food web based largely on decaying plants. Estuaries are tidally-influenced ecological systems where rivers meet the sea and fresh water mixes with saltwater.Estuary Food Web. The image above shows a cross-section of an estuary showing things typically found in estuary food webs and are listed here: (1) Sun, (2) Cattails, (3) Amphipods, (4) Detritus, (5) Bacteria, (6) Plant Plankton, (7) Animal Plankton, (8) Stickleback, (9) Immature Chinook, (10) Adult ChinookESTUARIES food web Many types of animals are found in estuaries. In fact, the complex food web found in an estuary helps to support an amazing diversity of animals..

Estuary food webs begin with the conversion of the solar's power to food power by way of crops and plankton. Simplified feeding relationships are proven in this diagram.There are two primary feeding pathways. One begins with massive vegetation such as mangroves, seagrass and rushes. When they die their leaves and roots are damaged down by means of bacteria and fungi to become detritus. Detritus is eaten through small animals similar to snails, worms and shellfish and they, in flip, are eaten by better creatures akin to fish and birds. A 2nd pathway starts with microscopic phytoplankton. They are eaten by tiny zooplankton which then turn out to be food for snails and shellfish.
