If you're talking about something that lives off of eating others to survive, this would be considered a heterotroph
If you're instead asking for what hunts others as prey, then you'd consider this a predator
<em>If this is a multiple choice question, try looking for one of those two as the answer.</em>
<u>Answer</u>:
<em>Sodium potassium pump works by following several steps.
</em>
<u>Explanation</u>:
<em>1. Carrier protein binds three molecules of Na+
</em>
<em>2. ATP is split, phosphate bonds to carrier.
</em>
<em>3. Carrier protein changes shape, and deposits Na on the outside of the cell.
</em>
<em>4. Carrier binds two molecules of K
</em>
<em>5. Phosphate is released.
</em>
<em>6. Potassium is released inside the cell
</em>
Sodium -potassium pump is essential to maintain the concentration of sodium and potassium outside and inside the cell respectively.
It is the function of sodium potassium pump to transport sodium out of the cell and potassium inside of the cell against a concentration gradient.
<em>Thus it is an active transport mechanism.

It’s D they compete for food and well they’re different species
Usually small Nonpolar molecules and further small molecules easily can pass through the lipid bilayer of the cell membrane. Larger molecules, polar and ionic substances require the use of specific proteins to help with movement across the membrane.
