Transcript of Fishy Food Chain

Take a journey through the flow of energy! Fishy Food Chain An energy path from one organism to another showing a linked series because each thing feeds on the one next to it in the series. Food Chain Organisms that transform energy from the Sun and use carbon dioxide and water to make food. Producers Now let's talk
about types of
consumers! Animals that get their energy only by eating secondary consumers. Tertiary Consumers We think Mercury exposure should
be limited for the safety of the public's health. Our View: Explore the vocabulary of food chains and energy pyramids. Food Web Overlapping food chains with different pathways for the flow of food energy in an ecosystem. Energy Pyramid A pyramid that shows how much energy transfers to the next level in a food chain. Consumers Organisms that eat producers or other consumers to obtain energy. Decomposers Organisms that get their energy by breaking down the remains of plants, animals, and waste into nutrients that are recycled to producers. Herbivores Animals that only eat plants or plant products. Carnivores Animals that eat other animals. Primary Consumers Organisms that get their energy by feeding on producers. Secondary Consumers Animals linked to the primary consumer in the food chain. Sources of Mercury dental fillings
thermometers
gold mining
batteries
fossil fuels Effects
of
Mercury Exposure brain damage
learning disabilities
blindness
Cerebral Palsy Our Solution: Companies should not be allowed to put Mercury in products people consume or to dump it as waste.
