Trophic Levels & Energy in Ecosystems
Energy Movement through Ecosystems Energy flows through ecosystems Trophic levels: feeding relationships
Trophic Relationships Primary producer – All autotrophs Primary consumer – Herbivores (eat producers) Secondary consumer – Carnivores (eat primary consumers) Tertiary consumer – Carnivores (eat secondary consumers) Quaternary consumer – Carnivores (eat tertiary consumers) Detritivore – Eat dead plant/animal matter Decomposer – Recycle matter back to soil
Food Chain A linear relationship that illustrates how energy flows in an ecosystem
Food Web A collection of interconnecting food chains
Energy flow in Ecosystems
Consumers are not all alike. Herbivores eat only plants.
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.
13.4-Food Chains and Food Webs
Flow of Matter and Energy. A food chain is a linear representation of who eats who in an ecosystem. Producers (plants, algae) Primary Consumer (herbivores)
2.2-Flow of Energy in an Ecosystem SPI 1 Interpret a diagram that illustrates energy flow in an ecosystem.
Section 2.2. Vocabulary Autotroph - Any organism that collects energy from sunlight inorganic substances to produce food. Heterotroph – An organism that.
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:
Biology Chapter 2.2 Flow of Energy In an Ecosystem.
the transfer of energy and matter in the form of food when one organism eats another organism.
Feeding Levels and Trophic Levels. Trophic level refers to the organisms position in the food chain 1 st trophic level = autotrophs, producers(plants,
Food Chains show how energy moves through the ecosystem in a linear fashion.
Energy and Ecology Ecosystem Components Producers – Basis of an ecosystem’s energy – Autotrophs: perform photosynthesis to make sugars – Chemotrophs:
Ecosystem Components Producers – Basis of an ecosystem’s energy – Autotrophs: perform photosynthesis to make sugars – Chemotrophs: Bacteria which use.
A producer is an organism that gets its energy from the sun. Example: sunflower plant.
Food chain- simple model that shows how matter and energy move through an ecosystem
Energy in Ecosystems Note: Organisms interact in order to obtain energy and resources necessary to survive.
