Grasses and plants are producers, guanacos are herbivores and are primary consumers and pumas are predators and secondary consumers
Because when you take the sand out it doesn't stay the same shape
4 moles of hydrogen = 4 * 1.008 = 4.032 grams
1 mole of helium = 4.003 grams
Difference is 4.032 - 4.003
= 0.029 g
I would choose Ground meat if i was in a hurry Hope this helps:)
