Mutualism: Both organisms benefit. Mutualism: Both organisms benefit.
Look how the majority of the this plants roots are connected to the symbiotic fungi.

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

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).
