<span>1: global warming can harm animals and plants in the ecosystem (even ourselves). global warming is when you litter and throw trash on the ground, and also the more trash that is sent to the dump can cause global warming to get worse. Trash in the ocean can harm animals, they can eat it and get sick, or get it caught on them. It makes our earth become warmer and energy levels change. It can also hurt our atmosphere.

Step 1
Glucose enters glycolysis pathway and glycolysis yields pyruvate, then pyruvate undergoes processing.
step 2
Pyruvate processing ;releases acetylCOA which joins the citric acid cycle.
Step 3
The citric acid cycle yields 2ATP and CO2 and also releases NADH and FADH2 to electron transport chain and chemiosmosis.
Step 4
Chemiosmosis and electron transport chain yields 25 ATP molecules and H2O Oxygen enters electron transport chain and osmosis.
It should be 3! That is the only logical answer to the question...
The answer should be 2. Skin fossilization is rare due to decomposition and scavengers.
