Active Transport - requires chemical energy because the process of transport is the movement of biochemicals from areas of lower concentration to higher concentration.
<span>Passive Transport - does not require energy because the process of transport is the movement of biochemicals from areas of higher concentration to lower concentration. </span>
Types of transport: Active Transport - endocytosis, cell membrane/sodium-potassium pump and exoctyosis
Passive Transport - diffusion, facilitated diffusion, and osmosis.
Types of particles transported: Active Transport - proteins, ions, large cells, complex sugars
<span>Passive Transport - anything soluble in lipids, small monosaccharides, water, oxygen, carbon dioxide, sex hormone, etc.</span>
Fish will eat tadpoles if they can get to them. The only way to stop them would be to give the tadpoles a space that the fish can't get to, like a shallow area with a barrier (plastic mesh would work but make sure the fish can't get caught in it) or lots of plants, or make a separate wildlife pond.
