From the ages 4-16, if you have a low calorie diet some symptoms can occur such as nausea, diarrhea, and fatigue. It will improve within a few weeks. Words from Lummus “Your body will start to store fat because it thinks it is not going to get anything”-Google
Linnaeus classified whole biodiversity on physical appearances, but there were some kind of organisms which couldn't categorize into either category. So, Micro-& macro-aspect of the life impacted so much, that's why we have very vast classification now, Morphology & Anatomy developed, which enhanced the tables under the main divisions of any kingdom
Hope this helps!
