Answer:

1. Explain why predators need to eat more than primary consumers.  

Explanation:

Predators need to eat more than primary consumers because in the trophic pyramid, primary consumers are at the bottom which means they receive the most energy because they eat the plants. As the pyramid goes on upwards, energy is lost each time, so that means by the time it reaches the top of the pyramid their is only about 0.1% of the energy we started with when the primary consumers ate the producers. Meaning, the predators need to eat more than the primary consumers because although the predators eat more than the primary consumers, they still at the end of the day get the same amount of energy just one eats more than another.

How is the chemical compositon of hydrothermal vents fluid different from surrounding sea water
ICE Princess25 [194]
HEY THERE!!

When seawater seeps down into the ocean crust and is heated by the magma, it undergoes lots of chemical reactions. When the fluid rises up through the seafloor, it carries many new chemicals with it, such as-- copper and zinc.
These chemical reactions also remove chemicals from the seawater, such as oxygen and magnesium.

So clearly vebtus fluid is different from sea water .
