Don’t Die

Don’t Die

Make lots of babies

Examples: stinger spray skin toxin

Defensive Chemicals: Irritating or poisonous chemicals

• You don’t want to camouflage, you want to stand out and be known.

• This butterfly tastes horrible to birds and is mildly poisonous,

• This butterfly tastes horrible to birds and is mildly poisonous, the other tastes good.

• This butterfly tastes horrible to birds and is mildly poisonous, the other tastes good.

If you don’t wantto die look like a snake.

Symbiosis: A long term relationship between two or more different species.

• Three types of symbiosis– - Parasitism– - Mutualism– - Commensalism

Parasitism: One organism benefits while the other is harmed.

“I’m sick of studying dumb

stuff” “Why should I care

about studying parasites?”

• 1 in 3 American suffers in some form from a parasite. – Learn about them to help yourself.

“I’m sorry that I yelled earlier.” “I

didn’t know that.”

• Caution! Disgusting parasites ahead.– Be prepared to be grossed out. Close your

eyes if needed.

• Caution! Disgusting parasites ahead.– Be prepared to be grossed out. Close your

eyes if needed.

eyes if needed.

BE WARNED NOW!

• Parasites damage their host by consuming tissues, and releasing toxins.

• Ascaris Infection “Worm Ball”– Removed from 10 year old boy.

• Human Intestine post surgery.– This section of the intestine was removed as

the worms created a blockage.

the worms created a blockage.

“I’m a parasitic worm, I have one mission…Don’t Die and make lots of babies…”

Mistletoe is a common

plant parasite

Mutualism: Both organisms benefit.

• Look how the majority of the this plants roots are connected to the symbiotic fungi.

• Fungus breaks down organic molecules and helps return those nutrients to plants.

• Cleaning symbiosis: One species gets food and shelter, the other has parasites removed.

• Defensive mutualisms: One species protects the other and gets some benefits for its help.

• The Sea Anemome and the Clownfish are a mutualism.

• The Sea Anemome and the Clownfish are a mutualism. – The Anemome gets small scrapes from the

clownfish, and the Clownfish gets protection.

• Dispersive mutualisms: One species receives food in exchange for moving the pollen or seeds of its partner.

Pollinator – Insects transfer pollen from one flower to the next, insects gets nectar.

• Pollination – Insects transfer pollen from one flower to the next, insects gets nectar.

“Wow!” “Look how this flower has evolved to be white, and shaped in a way so I can visit it.”

• Seed dispersal

Commensalism: One organism benefits while the other doesn’t benefit, or suffer harm.

• The remora just hitches a ride to grab some scraps after the kill.Shark

• The remora just hitches a ride to grab some scraps after the kill.Shark

Gets food scraps, protection, and a free ride.

• The remora just hitches a ride to grab some scraps after the kill.Shark

Isn’t hurt by the Remora but also doesn’t benefit.

Gets food scraps, protection, and a free ride.

• The remora just hitches a ride to grab some scraps after the kill.Shark

Isn’t hurt by the Remora but also doesn’t benefit.

Gets food scraps, protection, and a free ride.

Commensalism

“I’m not a cleaner bird.”“I’m just here for the protection”

“After my nap, can you please

feed me…Thanks.”

Coevolution: When two or more species influence each others evolution.

• Animals have special teeth and mouth parts to eat plants.

• Ladybugs eat aphids. – -

• Ladybugs eat aphids. –They’re vicious predators.

Check out that

warning coloration.

Or is it just a mimic?

• Crushing mouth parts

• Really sharp incisors for snipping plants and cutting through trees.

• Have long tongues to avoid dangerous plant ant mutualisms.

• Knock trees over / break branches to reach leaves and fruits.

• Burrow underground to eat tubers and the roots of the plants. (Naked Mole Rat)

• Many animals (living and extinct) swallow stones. The round stones smash plant matter together in the stomach as it rumbles to aid in digestion.

• Four chambered stomachs (many herbivores) – Uses bacteria to break down difficult plant

matter.

• Herbivores have gut bacteria that help them digest plant matter. The bacteria are fed plants, they grow, and then the cow processes the bacteria.

• Take in plant toxins: You are able to eat poisonous plants.

• Repair quickly and let them eat the non-essential parts of you.

• Mechanical Defenses: Thorns and serrated edges, and sap.

• This grass is very sharp and can cut skin easily.

• Stinging nettles.

• Chemical Defenses such as toxins: Plants become poisonous (nicotine, mustard, caffeine).

• Be extremely hard to digest.

• Think about celery, then be ten times harder to chew.

• You have protective insects, birds, or mammals that attack predators.– You feed your friends a bit (mutualism).
