Energy Flow in the Ecosystem
Food chain – shows which organisms each which in an ecosystem
Food pyramid – shows many organisms and what they eat
Trophic Levels troph = eat
Producer – makes its own food Example: grass, trees
Consumers – eat other organisms Herbivores/ primary consumers – eat plants Primary – first Carnivores/secondary or tertiary consumers – eat animals Secondary – second Tertiary – third Omnivores – eat plants and animals
Decomposer – breaks down waste Example: bacteria or fungus
Food Chains and Food Webs
Energy flow in Ecosystems
Consumers are not all alike. Herbivores eat only plants.
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.
Trophic level: All the organisms that are the same number of food-chain steps from the primary source of energy.
Energy Flows Through Ecosystems Sun: Makes all energy on Earth. Producers: Make their own food. Consumers: Get their food by eating other organisms. Decomposers:
Food webs model interactions within the community.
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.
Food Chains show how energy moves through the ecosystem in a linear fashion.
Basic Life Science Unit 1 Lecture Pages Chapter 12.
Food Web Producers, consumers, & decomposers. Three main components to the food web Producers Consumers Decomposers.
A producer is an organism that gets its energy from the sun. Example: sunflower plant.
Interactions in Ecosystems
How do organisms get energy?. Getting Energy Food chain – a sequence of connected producers and consumers Producer – an organism that makes its own food.
Decomposers are organisms that eat dead or decaying organisms. They carry out the natural process of decomposition. Fungi is the primary and most common.
Energy in Ecosystems Note: Organisms interact in order to obtain energy and resources necessary to survive.
Energy Transfer in an Ecosystem
Food Chains and Food Webs. Food Chain Events in which one organism eats another.
