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?
Food Chains and Food Webs

Food Chains, Food Webs, and the Transfer of Energy
Food chains, food webs and the transfer of energy
Roles of Living Things Chapter 4 Section 1. Organisms that make their own food from inorganic molecules and energy are called producers. –Plants are the.
DO NOW Answer the following: What is Ecology?.
Autotrophs/Producers A groups of organisms that can use the energy in sunlight to convert water and carbon dioxide into Glucose (food) Autotrophs are.
What is Energy?. Energy is the capacity for action/doing work.
Ecology Standards 6a. Know biodiversity is the sum total of different kinds of organisms & is affected by alterations of habitats 6b. Know how to analyze.
Chapter 37.1 and 37.2 – Ecology Dynamics The Flow of Energy Sun: ultimate source of energy The flow of energy is one way – from photosynthetic.
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 B: Chapter 2 Vocabulary Living Things Depend on One Another.
Modes of Nutrition Autotrophs have the ability to make their own food by the process of photosynthesis (write the word equation) Some bacteria use chemosynthesis.
2.2-Flow of Energy in an Ecosystem SPI 1 Interpret a diagram that illustrates energy flow in an ecosystem.
