FLOW OF ENERGY AND MATTER (FLUJO DE ENERGÍA Y LA MATERIA).

FOOD CHAINS AND FOOD WEBS TEKS: Readiness: 12C analyze the flow of matter and energy through trophic levels using various models, including food chains, food webs, and ecological pyramids

Slide 3 of 41 Flow of Energy and Matter In: Where does the energy for life processes come from? Write your response in your spiral. ¿De dónde viene la energía para los procesos de vida? Escriba su respuesta en su espiral. Copyright Pearson Prentice Hall

Slide 4 of 41 Food Chain & Food Web Simulation Follow directions Copyright Pearson Prentice Hall

Slide 5 of 41 Producers Without a constant input of energy, living systems cannot function. Productores: base de todas las cadenas alimentarias y redes Copyright Pearson Prentice Hall

Slide 6 of 41 Producers Sunlight is the main energy source for life on Earth. Some types of organisms rely on the energy stored in inorganic chemical compounds. Copyright Pearson Prentice Hall

Slide 7 of 41 Producers Producers/Autotrophs: Capture energy from sunlight or chemicals and use that energy to produce their food. Ex: plants, some algae, and certain bacteria Los productores / autótrofos: Capturar la energía de la luz solar o los productos químicos y usar esa energíapara producir sus alimentos. Ej: las plantas, algunas algas y algunas bacterias Copyright Pearson Prentice Hall

Slide 8 of 41 Producers Photosynthesis: Energy From the Sun Autotrophs capture solar energy to convert carbon dioxide and water into oxygen and energy-rich carbohydrates. Copyright Pearson Prentice Hall

Slide 9 of 41 Producers Photosynthesis is responsible for adding oxygen to—and removing carbon dioxide from—Earth's atmosphere. Copyright Pearson Prentice Hall

Slide 10 of 41 Consumers Consumers/Heterotrophs Organisms that rely on other organisms for their energy and food supply. Los consumidores o heterótrofos Los organismos que dependen de otros organismos para su energía y suministro de alimentos. Copyright Pearson Prentice Hall

Slide 11 of 41 Herbivores There are many different types of heterotrophs. Herbivores eat plants. Hay muchos tipos diferentes de heterótrofos. Los herbívoros comen plantas. Copyright Pearson Prentice Hall

Slide 12 of 41 Carnivores Carnivores eat animals. Los carnívoros comen animales. Copyright Pearson Prentice Hall

Slide 13 of 41 Omnivores Omnivores eat both plants and animals. Los omnívoros com en tanto plantas como animales. Copyright Pearson Prentice Hall

Slide 14 of 41 Detritivores Detritivores/ Scavengers feed on plant and animal remains and other dead matter. Detritívoros o basur eros se alimentan de restos de plantas y animales y la materiamuerta otra. Copyright Pearson Prentice Hall

Slide 15 of 41 Decomposers Decomposers, like bacteria and fungi, break down organic matter. Los descomponedores, como bacterias y hongos, descomponen la materia orgánica. Copyright Pearson Prentice Hall

Slide 16 of 41 Feeding Relationships How does energy flow through living systems? ¿Cómo funciona el flujo de energía a través de los sistemas vivos? Copyright Pearson Prentice Hall

Slide 17 of 41 Feeding Relationships Flows through an ecosystem in one direction, from the sun or inorganic compounds to autotrophs (producers) and then to various heterotrophs (consumers). Los flujos a través de un ecosistema en una sola dirección, a partir de los compuestos del sol o inorgánicos a los autótrofos (productores) y luego a variosheterótrofos ( consumidores). Copyright Pearson Prentice Hall

Slide 18 of 41 Feeding Relationships Food Chains series of steps in which organisms transfer energy by eating and being eaten. Cadenas Alimentarias serie de pasos en los que los organismos transfere ncia de energía por comer y ser comido. Copyright Pearson Prentice Hall

Slide 19 of 41 Feeding Relationships In some marine food chains, the producers are microscopic algae and the top carnivore is four steps removed from the producer. En algunas cadenas alimentarias marinas, los productores son las algasmicroscópicas y el carnívoro superior es de cuatro pasos de distancia de la productora.

Slide 20 of 41 Feeding Relationships Food Webs links all the food chains in an ecosystem together. las redes alimentarias vincula todas las cadenas alimenticias en un ecosistema en conjunto. Copyright Pearson Prentice Hall

Slide 21 of 41 Feeding Relationships This food web shows some of the feeding relationships in a salt- marsh community. Esta red alimentaria muestra al gunas de las relaciones de alimentación en una comunidad de marismas saladas. Copyright Pearson Prentice Hall

Slide 22 of 41 Feeding Relationships Trophic Levels Each step in a food chain or food web Producers – first Consumers - second, third, or higher Each consumer depends on the trophic level below it for energy. Copyright Pearson Prentice Hall

Slide 23 of 41 What is Biological Magnification? Like a magnifying glass that makes things look bigger, biological magnification makes a toxin get bigger, or stronger as well. This happens when a toxin is ingested or eaten and moved up the food chain from one living thing to the next. Copyright Pearson Prentice Hall

Slide 24 of 41 What is Biological Magnification? As it moves up the food chain, the toxin gets magnified or more concentrated. This happens because when larger animals eat smaller animals or prey, they don’t just eat one or two of these animals during their lifetime, sometimes they eat thousands or millions. Copyright Pearson Prentice Hall

Slide 25 of 41 What is Biological Magnification? Not only are these animals ingesting their prey, they’re also ingesting all of their prey’s toxins! Copyright Pearson Prentice Hall

Slide 26 of 41 Predict who you think is most affected by biological magnification in this food web? Copyright Pearson Prentice Hall

End Show Slide 28 of 41 Copyright Pearson Prentice Hall 3–2 The main source of energy for life on Earth is a.organic chemical compounds. b.inorganic chemical compounds. c.sunlight. d.producers.

End Show Slide 29 of 41 Copyright Pearson Prentice Hall 3–2 Organisms that feed on plant and animal remains and other dead matter are a.detritivores. b.carnivores. c.herbivores. d.autotrophs.

End Show Slide 30 of 41 Copyright Pearson Prentice Hall 3–2 How does a food web differ from a food chain? a.A food web contains a single series of energy transfers. b.A food web links many food chains together. c.A food web has only one trophic level. d.A food web shows how energy passes from producer to consumer.
