Energy Flow in Ecosystems Components of an Ecosystem living and non-living things interact with each other in an ecosystem.
biomass organic matter that is alive or was once alive Abiotic Factors vocabulary word!
abiotic non-living things in an ecosystem Abiotic Factors The four major abiotic components are: a. climate b. soil, dead material, and rock c. topography
d. natural disturbances Abiotic Factors Find the abiotic factors Under your definition, draw some abiotic things.
Biotic Factors vocabulary word! biotic living things in an ecosystem
Biotic Factors Biotic factors are anything that is living: a. plants b. animals c. microscopic organisms Biotic Factors
Find biotic factors Under your definition, draw some biotic things. Energy Roles Energy enters an ecosystem as
sunlight . Energy flows through an ecosystem in a cycle. Each organism has a role to play in this energy flow Producer Consumer
Decomposer vocabulary word! Producers Autotrophs
producers - make their own food and are the source of all the energy in an ecosystem Autotrophs Plants, algae, grass, trees, flowers, bacteria, plankton
Draw a few producers under your definition. vocabulary word!
Consumers Heterotrophs Consumers - Cannot make their own food. They get their energy from consuming other organisms. Heterotrophs
herbivores carnivores omnivores vocabulary word!
herbivore eats plants quickly draw an herbivore or two under the definition vocabulary word!
carnivore eats meat quickly draw a carnivore or two under the definition vocabulary word!
omnivore eats plants and meat quickly draw an omnivore or two under the definition Decomposers and Scavengers vocabulary
word! decomposers - break down waste and return the raw materials into the soil. Waste and dead organisms must be removed from the environment Bacteria
Fungi Carrion eaters like vultures, coyotes, maggots Decomposers and Scavengers quickly draw an omnivore or two under the definition
vocabulary word! Food Chains food chain diagram that shows the
flow of energy from one animal to another. first organism in a food chain is always a producer Next organisms are consumers Food Chain
Food Chain Quickly cut out the food chain and glue it on your paper under your definition. Food Chains Decomposers can be at any level
Food Web A food chain just shows one track of energy flow vocabulary word!
food web - consists of many overlapping food chains to show feeding relationships between organisms. Organisms can play more than one role in a food web Food Web
Food Web Food Web Quickly cut out the food web and glue it on your paper under your definition.
Trophic Level Organisms can be divided into trophic levels. producers are at the bottom Next are primary consumers (herbivores) Secondary consumers (omnivores
or carnivores) Tertiary consumers (omnivores or carnivores) Trophic Level Quickly cut out the trophic pyramid and glue it on your paper.
vocabulary word! Energy Pyramids energy pyramid - shows the amount of
energy that moves from one feeding level to another in a food web. At each level upward, the amount of energy decreases due to use. Energy Pyramids When an organism eats food, it obtains
energy The organism uses some of this energy for living (about 90%) Not all of this energy is available to the next consumer in line (only 10% moves to the next level)
Energy Pyramids The most energy is available at the producer level. The amount of energy at the producer level determines how many organisms an ecosystem can support. The least amount of energy is available
at the third level or tertiary consumer. Energy Pyramids Energy Pyramids Quickly cut out the energy pyramid and glue it on your paper under your definition.
Cycling of Energy Once an organism dies, decomposers take over and break down the material it was made of. These nutrients are put back into the soil.
Plants then use those nutrients along with sunlight to recycle that energy back into the food chain. Energy flows through an ecosystem in a cycle

The ISO standard now requires the strain to be measured directly - this gives obvious benefits, but has led to longer and wider gauge lengths, which tends to lower the maximum strain rates that can be achieved using servo-hydraulic equipment
