Food web competition

Thanks Jesse, Maggie and Soleil for drawing the food chain and energy transfer of an owl and its prey (and its food!). Soleil's drawing was a bit more developed, so she won the "food chain/candy necklace".

What about these TEETH?

Many might be noticing the color of the rodent incisor teeth (front teeth) as sort of "dirty orange".  Are these rodents DELIBERATELY disobeying their rodent parents by not brushing?

(please comment)

Another thing about teeth in rodents, most of you know the word "rodent" means "to gnaw" and "tooth" (latin: rodare and dentis), but did you realize the teeth grow throughout the rodent's life?  Those must be strong bones!

Please go to your email and read the rodent guide I am emailing to you--it will help you identify your bones!
