Commensalism: The Remora Fish feeds off the food scraps from the shark When one organism benefits, and the other isn’t helped or harmed (, ) The remora has a suction cup on the top of its head to attach to the shark. It eats the excess food that the shark doesn’t eat and also gets a free ride (using no energy of its own for movement).
Does the remora cause any harm to the shark?
Does the shark benefit from the remora in any way?

The remora does not harm the shark

And the shark benefits because they feed off of the parasites on the shark

Hope this helps :)

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

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.
