Transcript Living in Symbiosis

Living in Symbiosis
• A win – win partnership between two or
more organisms.
• They help each other.
Bees and Flowering plants
Flowers produce
nectar and pollen.
When the bees
come to eat the
nectar, they
pollinate the flowers
with pollen from
other flowers.
Acadia Tree and Stinging ants
The stinging ants
protect the tree by
attacking intruders.
The tree provides
shelter and food
while the ants
protect the tree.
Nile crocodile opening its mouth to permit the
Egyptian plover to feed on any leeches attached to
its gums.
Bird: food
Crocodile:
Clean teeth
and
remove
leeches
The dorsal fin of the remora (a bony fish) is modified into a
sucker with which it forms a temporary attachment to the
shark. When the shark feeds, the remora picks up scraps.
The shark makes no attempt to prey on the remora.
Shark: no harm
Remora: food
scraps
The clown fish is the only fish that does not get stung by
the sea anemone. The clown fish eats remains of
organisms the anemone has stung and eaten.
Clown fish:
habitat and
food
Sea anemone:
tentacles
cleaned to
allow
movement
Ox peckers eat the parasites off of large
animals like this African buffalo.
Bird: food
Water buffalo:
free of
parasites
Biofuels
Biofuel is any fuel that comes from biomass
— recently living organisms or their
byproducts, such as manure from cows
and horses.
It is a renewable energy source, unlike other
natural resources such as petroleum, coal
and nuclear fuels.
Complete Metamorphosis
• The changes in the shape of an
organism’s body as it grows and matures.
• Complete metamorphosis has four steps:
– Eggs
– Larva (wormie looking)
– Pupa (usually involves a cocoon/crystalis)
– Adult
Beetles
Butterflies
Ants
Lady bugs
Incomplete Metamorphosis
• Changes body shape but the baby organism
usually looks like a mini adult.
• These organisms also molt (shed their outer
skeleton) .
• Incomplete metamorphosis has three steps:
– Eggs
– Nymph (looks like a mini adult)
– Adult
• Grasshoppers
• Locusts
• Cockroach
• Crickets
