The formula for BMI is
BMI= kg/m^2
A BMI of 25.0 or more is overweight and a healthy and average BMI ranges from 18.5 to 24.9. However, BMI only applies to adults from 18-65 years old. You can always go online and search up BMI calculator and all you need to do is enter your weight and height.
Start with your producers, or plants (grasses, flowers, etc.). Then your 1st level consumers (herbivores), like grasshoppers, mice, etc. Then your second level producers (carnivores and omnivores) that eat the herbivores (like birds). And keep going, knowing each of the levels get eaten by each other. 10% of energy is transferred in each level. An example might be...
Grass > Mice > Hawk > Vulture
