Mutualism
The Yucca Tree is a type of perennial shrub and tree
found in parts of North and South America. They are
know for their tough, sword shaped leaves and whitish
flowers.
Yucca Moths have white wings to blend in with flowers
on the plants. Their lifecycle is about one year.
The Yucca Tree and the Yucca Moth share
a mutually beneficial relationship, each
dependent on the other for survival. The
tree receives the benefit of pollination from
the moth, and the moth feeds off the seeds
on the yucca tree. The female yucca moth
is the only pollinator of the yucca tree, and
the tree is the only host plant of the yucca
moth. In fact, this relationship is so
specialized, each yucca tree species is
pollinated by only one type of yucca moth.
Mutualism
• 1 – One relationship is the oxpecker and zebra. The oxpecker
eats all the parasites/ticks off the zebra’s body. Another
relationship is the bee and flower. When the bee lands on a
flower it gets pollen on its body, it goes to the next flower and
rubs the pollen on that flower.
• 2 – Mutualism is when one organism benefits another
organism. The oxpecker takes all the dangerous parasites off
the zebra’s skin. The bee takes the pollen off one flower and
rubs it on another. This helps the flower grow. All mutualism
benefits an organism.
Parasitism
• 1- One example of parasitism is tapeworms. They feed on your intestines
and can harm you greatly. Another example are fleas. They can latch on to
their hosts and suck their blood making them itch. The last example are
barnacles they don’t do much harm but can make whales itch.
• 2- Parasitism is when one organism harms another. An example is when
tapeworms feed on your intestines and harm you. Another example is
when fleas suck your blood and make you itch. The last example are
barnacles that cant do much harm but are annoying to whales.
Commensalism
• 1- One example of commensalism is the cattle egret. The
cattle egret eats all the insects that are in the cattle way.
Though this doesn’t effect the cattle in any way shape or
form.
• 2- Commensalism is when one organism benefits itself but
doesn’t effect the other organism. The cattle egret gets food
but doesn’t effect the cattle. Another example is the barnacle
eater. The barnacle eater eats all the barnacles off whales.
When this happens, the whales are unaffected.
