Which model can be used to trace genetic inheritance 1) life cycle 2) pedigree chart 3) food web 4) energy pyramid

The answer is pedigree chart.

A pedigree chart is like a family tree diagram, it is used to show the frequency of a particular characteristic in that family.

Normally, male is represented by a square shape, and female a circle. If the person shows the characteristic, their shape may be colored or vice versa.

With the pedigree chart, we can trace out the inheritance of the characteristic or find the possibility of having that characteristic in the next generation.

It's either -limiting factors or -scarce resources but i'd go with my first answer since the food and water are abundant they really aren't scarce
