The Marine Biome Marine Food Chains
Biodiversity The variety of living things in a particular area.
Ecosystems The focus of all ecosystems is food. Energy is passed on by food.
Trophic Levels Autotrophs (producers): ▫ Make their own food using energy from the sun. ▫ Ex. Plants, algae, bacteria
Trophic Levels Heterotrophs (consumers): ▫ Need to eat other organisms to get energy. ▫ Herbivores: Eat plants, algae, bacteria ▫ Omnivores: Eat plants and animals ▫ Carnivores: Eat animals only
Trophic Levels Scavengers: ▫ Eat dead material. ▫ Ex: lobster, shrimp Decomposers: ▫ Break down dead material. ▫ Ex. Bacteria
Food Chains Energy is recycled through the trophic levels.
Food Chains The arrows show the direction of energy flow. They always begin with a producer.
Food Web Shows many food chains interacting in an ecosystem.
Energy Transfer in Ecosystem
Food Chains and Food Webs
Food chains, food webs and the transfer of energy
Ecology The study of the interaction of living things with their environment.
How is an organism’s energy role determined in an ecosystem?
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 Flow. All energy in an ecosystem comes from…….
Part 2. ENERGY Where does all of the energy on planet earth come from?
2.2-Flow of Energy in an Ecosystem SPI 1 Interpret a diagram that illustrates energy flow in an ecosystem.
Energy Flow In An Ecosystem Unit 11 - Ecology. Producers The most important part of an ecosystem Without a constant energy source, living things cannot.
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:
Chapter 3: How Ecosystems Work Section 3.1: Energy Flow in Ecosystems.
Organism. An individual animal, plant, or single- celled life form.
Food webs model interactions within the community.
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?
ECOLOGY. Ecology The study of interactions among organisms (biotic factors) and their environment (abiotic factors)
