Energy Transfer in EcosystemVocabulary Trophic = nutrition Autotrophs Heterotrophs
Heterotrophs Consumers1. Scavengers feed on the tissue of dead organisms (both plans and animals)
Heterotrophs Consumers 2. Herbivores eat ONLY plants.
Heterotrophs Consumers 3. Carnivores eat ONLY animals.
Heterotrophs Consumers 4. Omnivores eat BOTH plants and animals
Heterotrophs Decomposers absorb any dead material and break it down into simple nutrients or fertilizers
Transfer of Energy
Trophic Levels… …represent different levels in a food web.
Food Webs We represent the energy flow from one trophic level to another as a food web. (Most organisms eat more than one different species.)
Food Web Notice that the direction the arrow points The arrow points in the direction of the energy transfer, NOT “what ate what”.
Ecological Pyramid 1. Which level has the most energy?2. Which level has the most organisms? 3. Which level has the fewest organisms? 4. Which level has the least energy?
Autotrophs Heterotrophs Consumers Carnivores Herbivores Decomposers
Food chains, food webs and the transfer of energy
Food Chains, Food Webs, and the Transfer of Energy
Part 1: Food Chains, Food Webs, and the Transfer of Energy
Energy Flows Trophic Levels and Food Pyramids. Autotrophs A groups of organisms that can use the energy in sunlight to convert water and carbon dioxide.
Unit 2, Part 3 Notes Food Chains, Food Webs, and the Transfer of Energy.
Section 2.2. Vocabulary Autotroph - Any organism that collects energy from sunlight inorganic substances to produce food. Heterotroph – An organism that.
Energy Flows Through Ecosystems Sun: Makes all energy on Earth. Producers: Make their own food. Consumers: Get their food by eating other organisms. Decomposers:
9/18/14 Objective: How do living things get their energy? Do Now:
Biology Chapter 2.2 Flow of Energy In an Ecosystem.
Food webs model interactions within the community.
Energy Flow in an Ecosystem. Autotrophs: organisms that manufacture their own nutrients using stored energy or energy from the sun –Examples? Heterotrophs:
The Marine Biome Marine Food Chains. Biodiversity The variety of living things in a particular area.
the transfer of energy and matter in the form of food when one organism eats another organism.
Lesson 6. Producer Living things that make their own food.
Chapter 2.2 Nutrition and Energy Flow. 2.2 Nutrition and Energy Flow Autotroph- uses sunlight or chemical compounds to make own nutrients Ex. Plants,
9/18/13 Objective: How do living things get their energy? Do Now: Where does the ultimate source of energy come from for all of life?
Food Chains, Webs & Pyramids! 1) The Passage of Energy The Sun The source of energy for all life on the planet Producers (Autotroph) Use the sun’s energy.
Food Chains & Food Webs. Autotrophs A groups of organisms that can use the energy in sunlight to convert water and carbon dioxide into Glucose (food)
