Use this picture to answer the questions below.
1. – 2. Define biotic factor. Name some biotic factors in the picture above.
Something that is alive; big fish, turtle, lily pad, ferns,
deer, tree, cattail, raccoon, little fish, dragon fly…
3. – 4. Define abiotic factor. Name some abiotic factors in the picture above.
Something that is not alive; dead log, water, air, sun,
dirt
5. – 6. Define population. Where can I find a population in the picture above?
All of 1 kind of animal interacting in an area;
population of lily pads, population of cattails, population of
little fish, population of ladybugs
7. – 8. Define ecosystem. Where can I find an ecosystem in the picture above?
All the living and nonliving things interacting in an
area; the picture is an ecosystem
9. – 10. Define community. Where can I find a community in the picture above?
All of the living things interacting in an area; the
cattails, grass, deer, frogs, raccoons, daisies, turtles,
dragonflies, etc. form a community
11. – 12. Define niche. What is in the same niche as the frog?
An organism’s role/job in an ecosystem. The frog can
live on land and water and is a consumer. So is the turtle.
13. – 14. Define habitat. What is in the same habitat as the deer?
Where an organism lives in an ecosystem. The deer
lives on land away from the water. So do the raccoon and
hawk.
15. – 16. Define producer. Where can I find a producer in the picture above?
An autotroph, something that makes its own food;
cattails, ferns, trees, lily pad, grass, daisies
17. – 18. Define consumer. Where can I find a consumer in the picture above?
A heterotroph, something that eats other things;
dragonfly, ladybug, deer, big fish, turtle, frog, hawk,
raccoon, little fish, water strider
19. – 20. Define decomposer. Where can I find a decomposer in the picture above?
Helps things rot. You can’t really see them, but the
dead log has some bacteria or termites or fungi that are
making it decompose. Same thing with those bubbles near
the big fish. Most likely coming from bacteria decomposing
ings at the bottom of the pond.

stored in the next. Explain
why
this number is so low.
3 reasons:
 Not all energy is eaten (some organisms left behind)
 Not all eaten is useful (bones, fur, cellulose, etc.)
 Not all useful is stored (some used for life processes)
Finally! Something not about that stinkin’ picture!
Define and give an example of:
30. – 31. predation
Raccoons eat frogs, frogs eat dragon flies, big fish eats
little fish,
( +, - )
Tapeworm in human intestines, heartworm in
cats/dogs
32. – 33. parasitism
( +, + )
Nitrogen fixing bacteria in plant roots (plant gets
Nitrogen, bacteria gets habitat), E. coli in our large
intestine (we get wasted broken down, bacteria get warm
place to live)
34. – 35. mutualism
( +, 0 )
Dust mites on our eye lashes, scalp (don’t really bother
us, feed on dead skin)
36. – 37. commensalism
Mutualistic Relationship
Organisms Involved
Interaction of organisms involved
Root Nodules
Legumes/Rhizobium
Rhizobium gets carbohydrates & provides
fixed forms of nitrogen and ammonia to
the legume
Lichen
Fungus/algae or
cyanobacterium
Fungus sends acids to the rock and
dissolves minerals. Alga or
cyanobacterium carries on photosynthesis
Termite/Trichonympha
Trichonympha/Pyrsonympha and Pyrsonympha
The Trichonympha and Pyrsonympha
digest wood for the termite.
Ants and Acacia
Ants feed from acacia nectaries and eat
beltian bodies/nodules. Ants protect the
acadia from herbivores and girdle branches
to let more light in to the acacia.

Interaction of the organisms involved
Epiphytes
Epiphytes - Various
mosses, ferns, bromeliads,
and orchids/Other plants.
Epiphytes grow on other plants obtaining nutrients from
rainwater and decaying leaves –not from the host.
Remora
Remora/Fish (sharks) and
turtles
Attaches to sides of other fish and turtles and eats food
they drop.
Clown fish
Clown fish/ Sea anemone
The clown fish lives among the deadly tentacles of a sea
anemone and eats food left by the sea anemone.
Barnacles
Barnacles/whales and
manatees, ships and other
things in the ocean.
Barnacles attach as harmless hitchhikers. Some species
of barnacles are found only as commensals on the jaws
of whales. And there are other species of barnacles
found only as commensals on those barnacles. Barnacles

Symptoms of Disease
Host
Symptoms of malaria include fever and
flu-like illness, including shaking chills,
headache, muscle aches, and tiredness.
Nausea, vomiting, and diarrhea may also
occur. Malaria may cause anemia and
Mosquitos bites to
Orthonectidea
jaundice (yellow coloring of the skin and Mosquitoes

eyes) because of the loss of red blood
cells. Infection with one type of malaria, P.
falciparum, if not promptly treated, may
cause kidney failure, seizures, mental
confusion, coma, and death.

Platyhelminthes
Pigs to humans
Abdominal pain or diarrhea and excess gas
after becoming infested with tapeworm. Also
may experience nausea and vomiting anal
itching or inflammation, hunger, fatigue, loss of
appetite, and weight loss occur if the condition
is not treated. Rarely other organs of the body,
including the brain, can be affected.
Snails to humans
Symptoms characterized by an increase of
bowel movements or diarrhea, usually
accompanied by increased numbers of
circulating eosinophils, abdominal
discomfort and nausea. A few may notice Snails
weight loss and fatigue, and some may be
asymptomatic. The rickettsia, though fatal
to 80% of untreated dogs, is not known to
infect humans.
Pigs
Often no symptoms. May be a local
Hookworm/
Ancylostoma
duodenale or
Necator

Nematoda
Contaminated soil
or stool
irritation of the skin where the worm
penetrated or even an itchy rash. In the
lungs, there may be asthma-like
symptoms or pneumonia. The most
common symptoms of Hookworm
infection, however, are from their
residence in the intestine. Here,
Hookworm can lead to abdominal pain,
diarrhea, weight loss, loss of appetite
and excessive gases. In chronic
infections, the patient may become
anemic as the worms feed on the
individual's blood. The loss of blood
leads to a loss of iron and protein;
causing difficulty in breathing, pale
complexion, tiredness and weakness,
fast heartbeat, generalized swelling or
bloating and impotence. If the infection
lasts a very long time or is very severe,
there may be a slow growth, heart
problems or even heart failure.
