What is the main negative effect of slash and burn deforestation in rain forests?

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

tobey

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
