Answer:
the ability to form stable bonds
I'd say heat, more specifically sunlight.
Why?
Because sun is the form of energy needed for plants to grow and live. Plants in turn are the form of energy needed for herbivores to live that later on turn out to be the form of energy needed by the carnivores. When these die, decomposers will be the ones to take advantage of the energy.
As you can see an ecosystem has already been formed: producers, secondary consumers, tertiary consumers or decomposers.
Hope it helped,
Happy homework/ study/ exam!
The number of weight gained in pregnancy should be different based on the BMI. Assuming Sadie BMI is 25-29.9kg/m2 then the normal weight gain for single pregnancy would be 15 to 25lbs.
Higher BMI will cause the normal weight gain become lower. For BMI >30kg/m2 normal weight gain would be 11-20lbs
