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?
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.
Energy in Ecosystems Note: Organisms interact in order to obtain energy and resources necessary to survive.
The Marine Biome Marine Food Chains. Biodiversity The variety of living things in a particular area.
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.
the transfer of energy and matter in the form of food when one organism eats another organism.
Ecosystem Structure. Passing of Energy All Energy starts from the sun Photosynthetic plants convert energy from the sun into food The energy moves through.
Energy Flow in an Ecosystem. Autotrophs: organisms that manufacture their own nutrients using stored energy or energy from the sun –Examples? Heterotrophs:
Energy Flow in an Ecosystem. Energy flows through an ecosystem as one organism eats another. The way in which energy flows can determine how many species.
Unit 2, Part 3 Notes Food Chains, Food Webs, and the Transfer of Energy.
Notes Energy Flow in an Ecosystem. Initial Energy Source Sunlight is the main energy source for life on Earth!
Lesson 6. Producer Living things that make their own food.
Match up the word with the correct definition and picture using the cards provided by you teacher, For those words you do not know, set them to the side,
Food chain Presented by Zaib Unnisa TOPICS UNDER DISCUSSION l Food Chain l Food Web l Types Of Tropic Levels l Ecological Pyramid.
Unit 10 Part 2 Notes Energy Flow in an Ecosystem.
Producers aka Autotrophs A group of organisms that can use the energy in sunlight to convert water and carbon dioxide into Glucose. Energy for all.
Energy Flows Through Ecosystems Sun: Makes all energy on Earth. Producers: Make their own food. Consumers: Get their food by eating other organisms. Decomposers:
Energy Transfer in an Ecosystem. Producer vs Consumer organism that eats producers or other consumers organisms that make their own food using sunlight.
Chapter 5: Energy Part 1: Food Chains, Food Webs, and the Transfer of Energy.
Transfer of Energy in Living Systems. Autotrophs A group of organisms that can use the energy in sunlight to convert water and carbon dioxide into Glucose.
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)
Biology Chapter 2.2 Flow of Energy In an Ecosystem.
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,
9/18/14 Objective: How do living things get their energy? Do Now: Recall the levels of organization, what is an ecosystem?
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 webs model interactions within the community.

Chapter 3: How Ecosystems Work Section 3.1: Energy Flow in Ecosystems.
What is Energy?. Energy is the capacity for action/doing work.
Autotrophs/Producers A groups of organisms that can use the energy in sunlight to convert water and carbon dioxide into Glucose (food) Autotrophs are.
A producer is an organism that gets its energy from the sun. Example: sunflower plant.
Class Notes 5: Energy Flow in Ecosystems I. Energy Flow A. Ecologists trace the flow of energy through communities to discover nutritional relationships.
2.2-Flow of Energy in an Ecosystem SPI 1 Interpret a diagram that illustrates energy flow in an ecosystem.
ECOLOGY VOCAB. all the food chains that exist in a community. Food web.
Chapter 13: Energy and Nutrients Section 13-2: Energy Flow in the Biosphere.
Energy pyramid. How do animals use the energy from food? Are there more plants, herbivores, or carnivores? Why?
3.1 Energy Flow in Ecosystem Mrs. Trimble Mrs. Perryman.
Ecology Notes Food Chains, Food Webs, and the Transfer of Energy.
Food Web Producers, consumers, & decomposers. Three main components to the food web Producers Consumers Decomposers.
Unit B: Chapter 2 Vocabulary Living Things Depend on One Another.
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.
TODAY’S LEARNING TARGET #4 I can show relationships of organisms through food chains, webs, and trophic levels. (you will be writing this down tomorrow)
Ecology Lesson 6 How does energy flow through an ecosystem? What energy roles do organisms play in an ecosystem? How much energy is available at each level.
Chapter 2 SECTION 2 NUTRITION AND ENERGY FLOW. Ecology is the study of interactions between organisms and their environment. Ecology combines the science.
Energy Flow: Autotrophs Sunlight is the main source of energy for life on Earth. Autotrophs (also known as producers) have chlorophyll that captures the.
Food Chains, Webs, and Pyramids. Ecosystems are divided into different sections called trophic levels Each trophic level represents a transfer of energy.
Ecology Notes Carrying Capacity, 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.
Organism. An individual animal, plant, or single- celled life form.
