In order to live animals need energy.
Some animals get the energy they need to live from eating plants and other vegetation.
Some animals get their energy from eating other animals.
Some animals eat both plants and other animals.
Energy from food A food chain describes how energy in an
ecosystem flows from one organism to another.
Producers- Make their own food Consumers- Living things that cannot
make their own food– Herbivores- eat only plants or producers– Carnivores- eat only other consumers– Omnivores- eat plants and animals
Decomposers- break down the decaying remains of dead producers and consumers
Food Chains
A food chain describes how energy in an ecosystem flows from one organism to another.
******EXAMPLE******1. Sun2. Producers- plants capture the sun’s energy to
make food3. 1st level (primary) consumer- ex. Catepillar4. 2nd level (tertiary) consumer- ex. Bird5. 3rd level consumer- ex. Cat6. Decomposers- fungus, bacteria, earthworms
Food Chain Order in which
energy is transferred from one organisms to another
Each part of a food chain is a link connected to other links.
The Sun Without the sun, there would be no
food chain It is the beginning of any food
web/food chain
Consumers
Primary consumers (1st level)- eat only plants
HERBIVORES Secondary Consumers (2nd Level)- eat
other consumers– Omnivores or carnivores
Tertiary Consumers (3rd level)- Eat secondary consumers– omnivores/carnivores
Consumers Humans are consumers…. Which level would we be? Primary,
secondary or tertiary?? Humans are mostly considered “top of the
food chain” Question- If a human was stranded in the
ocean with no raft or boat…would we still be the “top of the food chain?” why or why not??
Decomposers Organisms that break down dead or
decaying plant and animal matter
There is a difference between a decomposer and a scavenger!!– Scavenger= lazy consumer
Food Chains/Webs Food Chain- how energy is
transferred from one organism to another– Producers, Consumers, decomposers
Food Web- overlapping food chain
Think about your community of animals you have in front of
you. What would happen if one of the
animals had a disease and all died… Take one animal away from your
group. Write down what you think would
happen…
