A punnet square determines all of the ways in which alleles can combine. It may be used to predict ratios of offspring genotypes and phenotypes. However, Punnet squares cannot determine actual outcomes. They can only predict the possibility for things to happen. The exception to this takes place when the cross occurs with two homozygous dominant or recessive genes and the resulting offspring is either be 100% homozygous dominant or recessive.
Answer:
1,000 kcal
Explanation:
As a general rule, every trophic level only gains 10% of the energy from the trophic level.
So, the grass has 100,000 kcal of energy. Assuming the bird eats grass, it only gets 10,000 kcal of energy. Assuming the fox eats the bird, it only gains 1,000 kcal of energy.
