How does natural selection lead to the formation of new types of organisms

once a population is introduced to a new environment, they can only learn to adapt and allow mutations to help them develop new traits or die off. the organisms that are not fit for survival will die off leaving those fit for survival to reproduce and their offspring will inherit the same "fit" genes and be able to survive long enough to reproduce offspring that have the traits fit for survival and so on (the cycle continues with mutations to help develop even more fit genes)

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this
