Explanation:

1. Most of the energy that isn't stored is lost as heat or is used up by the body as it processes the organism that was eaten.

2. Given energy = 1000kcal,

then after 1st trophic level, it comes to

10/100 × 1000 = 100kcal.

then after 2nd trophic level, it comes to

10/100 × 100 = 10kcal.

Hence, After 2 trophic levels the given energy drops down to 10kcal.

sexual reproduction produces offspring with novel combinations of genes. species that reproduce sexually must maintain two different types of individuals, males and females, which can limit the ability to colonize new habitats as both sexes must be present.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
