Here’s our CARBON CYCLE!

CARBON CYCLE!

CARBON CYCLE! CO 2 in the atmosphere

And now for a story…

Once upon a time…

there was a bacterium named Rhizo!

there was a bacterium named Rhizo!

there was a bacterium named Rhizo! I have NO nucleus…

All of Rhizo’s other friends split. So, Rhizo was all alone.

Rhizo went high & low looking for a friend…but too many organisms were scared of him.

Rhizo was all alone…. for so long…

Rhizo was all alone for so long, that he thought about burying himself.

And he did…

And he did…

But WAIT, that’s not the end of our story!

Rhizo found new friends in the soil!

Rhizo found a new friend in the soil! It was Myco, the happy fungi! I am primitive and have no nucleus. I’m a WHAT? Like that’s so primitive! I have organelles. I’m ______!

Rhizo found a new friend in the soil! It was Myco, the happy fungi! I’m a bacterium, so I’m a PROKARYOTE Like that’s so primitive! I’m EUKARYOTIC!

And all the plants loved whenever Rhizo and Myco decomposed all the dead stuff.

Rhizo & Myco gave plants what? I poop it out! You mean you EXCRETE!

NITROGEN-fixing between plants and their bacteria & fungi buddies is ALL MUTUALISTIC. I poop it out! NITRATES! You mean you EXCRETE!

MORAL: MUTUALISTIC BACTERIA & FUNGI WORK HAPPILY and I use TOGETHER WITH PLANTS to make NITRATES! it to PROTEINS I poop it out! You’re talking NITRATES! ALL TOGETHER: MUTUALISTIC

Here’s our NITROGEN CYCLE!

Here’s our NITROGEN CYCLE!

NITROGEN CYCLE! LIGHTNING ATMOSPHERIC NITROGEN (N 2) INDUSTRY NITRATES ANIMAL WASTES NITROGEN-FIXING FUNGI & BACTERIA!

NITROGEN CYCLE! LIGHTNING ATMOSPHERIC NITROGEN (N 2) INDUSTRY NITRATES ANIMAL WASTES NITROGEN-FIXING BACTERIA!!!
