Symbiosis- A close relationship between two organisms where at least one organism benefits.
Types of symbiotic relationships◦ Mutualism (both benefit)
◦ Commensalism (one benefits and one not affected
◦ Parasitism (one benefits and one is harmed)
GUIDE CARD
Mutualism occurs when species interact in a mutually
beneficial manner.
The oxpecker gets food (ticks and insects disturbed in the grass) and a safe haven
from the rhinoceros, and the rhinoceros has parasites (ticks) removed.
GUIDE CARD
Example of mutualism: cleaner shrimp and a grouper fish
Cleaner shrimp picks off parasites from the grouper’s mouth and
gills. Both benefit.
GUIDE CARD
Mutualism
Mycorrhizal fungi (threads) covering aspen roots: fungi aid in water
and nutrient absorption by the aspen and the aspen provides sugars
and other food molecules to the fungi.
GUIDE CARD
The remora attaches to a shark and rides to where the
shark makes a kill. The remora eats the left over
scraps of meat.
GUIDE CARD
Commensalism: Barnacles and Grey Whales
Barnacles attach to the head of the whale and feed on plankton
where ever the whale swims. The barnacles don’t harm the
whale.
GUIDE CARD
Vampire bats feed on the blood of
mammals without killing their host.
GUIDE CARD
Parasites feed off other organisms called “hosts”.
Parasites usually don’t kill their host.
GUIDE CARD
Ectoparasites- Live outside the host◦ Example: ticks and humans
GUIDE CARD
Head louseMite
bedbug
GUIDE CARD
Live within the host ◦ Example: guinea worms
GUIDE CARD
Tapeworm
Hookworm
Roundworm
GUIDE CARD
•ecological relationships in which
one organism (population, species)
benefits and the other is harmed
GUIDE CARD
A predator is an animal that hunts
other animals for food. The animals
that are eaten are the prey.
Classify the following pictures as to what type of
interrelationship exist among living things.
◦Write PREDATION, MUTUALISM, COMMENSALISM, or PARASITISM
In your worksheet.

ACTIVITY CARD #1
ACTIVITY CARD #1
_____1. Eagles build their nests on treetops. The eagle are protected by the thick foliage. The trees are not harmed or benefited by the eagles.
_____2. Many other birds find food and shelter in the trees in the forests. The birds help disperse the seeds of the seeds.
_____3. Monkeys climb or swing among the branches of trees. The trees provide shelter to the monkeys. Hunters have a difficult time catching them.
_____4. Bacteria and fungi feed on dead plants and animals. They break the dead organisms into simple nutrients the plants can use.
_____5. Cats are hunting mice in the corners of the house.
ACTIVITY CARD #2
Analyze the following pictures. Identify what ecological relationship
exists in the living organisms.

Mutualism
ASSESSMENT CARD
Choose the letter of the correct answerRead the questions carefully then choose the best
answer on the choices given below.
a. commensalism
b. mutualism
c. parasitism
d. predation
ASSESSMENT CARD
a. Aphids produce honeydew needed by ants. In return, ants protect aphids from other insects.
b. The ants eat the aphids.
c. The aphids produces honeydew but the ants do not give any help nor harm the aphids.
d. The aphids live on the ants habitat.
ASSESSMENT CARD
a. Mutualism mean that both members of a species benefit from living together. Parasitism means that one member of a species benefits without harming or benefiting the member of another species.
b. Mutualism means that one member of a species benefits without harming or benefiting the member of another species. Parasitism means that both species' members benefit from the relationship.
c. Mutualism means that one member of a species thrives at the expense of the member of the species. Parasitism means that one member of a species thrives at the expense of the member of the species.
d. Mutualism means both members of a species benefit from living together. Parasitism means that one member of a species thrives at the expense of the member of the species.

We Are Not Immune!
When it rains, most of the chemicals sprayed onto crops get washed into rivers, and eventually the sea.

Once a poisonous chemical is in the food chain, there is a good chance that humans will be affected.
