A diagram that shows how energy in food flows from one organism to another
Food chain
All energy on Earth ultimately comes from what source?
The sun
Living parts of an ecosystem
Biotic factors
Name 5 examples of producers.
Examples include: trees, bushes, grass, ferns, flowers...
Two examples of decomposers are...
Mushroom, Fungi, Bacteria, Mold, Lichen, Worms, Snails, Slugs...
A diagram that shows the feeding relationships between organisms in an ecosystem
Food Web
The arrows in a food chain or web represent what?
They show the movement of energy flowing between organisms.
Nonliving parts of an ecosystem
Abiotic factors
Living things that eat other living things for energy are known as...
Consumers
**Double Points** A decomposer that is found in every ecosystem is...
Bacteria
In a food chain or web, there are 3 types of consumers based on what they eat. These are called...
Herbivores, Carnivores, and Omnivores
Why might an organism have more than 1 arrow coming from them in a food web?
More than 1 organism may eat them.
A snowshoe hare lives in the Tundra and has white fur. What is the purpose of this for the snowshoe hare?
To help the snowshoe hare blend in to hide from predators.
sun --> grass --> rabbit --> coyote
Rabbit
By creating nutrients, which type of living thing do decomposers help the most?
a. Plants
b. Reptiles
c. Large birds
d. Rocks
a. Plants -- because decomposers create nutrients & soil to help plants grow
Explain how producers, consumers & decomposers are linked in a food chain.
Producers are eaten by consumers. When consumers die, decomposers feed on them.
In this food chain, the ______ is the predator.
sun --> rose --> caterpillar --> small bird
Small bird
**Double Points** Which choice gives an example of a producer, a consumer, and a decomposer?
A. bacteria, grass, flower
B. clover, rabbit, mushroom
C. fungi, mushroom, flower
D. cow, eagle, mouse
B. clover, rabbit, mushroom
The third animal in any food chain is known as...
Explain the importance of decomposers in an ecosystem.
Decomposers are nature's recyclers - they eat dead & decaying material to break it down into soil, so that dead things don't pile up in nature.
Where are producers located in a food chain/web? Why?
Producers are located at the "bottom" of a food chain or web, because they create their own food from the sun & get eaten by other living things.
Which list shows a possible order in which energy moves through a food chain?
a.herbivore, carnivore, sun, producer, decomposer
b. sun, producer, herbivore, carnivore, decomposer
c. sun, producer, predator, consumer, decomposer
d. producer, sun, carnivore, herbivore, decomposer
b. sun, producer, herbivore, carnivore, decomposer
Oak trees produce seeds that are contained in acorns. Blue jays eat the seeds in acorns. Blue jays also collect acorns and hide them in the ground, often far away from the parent oak tree. Blue jays do not eat the seed of every acorn they hide. How do oak trees benefit from blue jays’ collecting and hiding acorns?
Blue jays help with the reproduction of oak trees because new oak trees will grow where the acorns are buried.
