This is true.

Facilitated diffusion is a process by which molecules are transported across the plasma membrane with the help of membrane proteins.

It is a type of passive transport in which no energy from the cell is required for the process because a concentration gradient  exists that allows movement of particles without expending cellular energy. 

 Materials diffuse across the cell membrane with the help of membrane proteins some of which are known as carrier proteins.

Membrane proteins are proteins that are attached to, or associated with the membrane of a cell or an organelle.

What causes the dangerous red tides in the ocean?
Leto [7]

<span>Red tides are formed by dinofllagelata, eucaryotic flagellate organisms. Dinoflagellates are marine plankton which means they drift on the surface of the sea.

The bloom is often red colour so the phenomenon is called red tides. </span>Under such circumstances, they can produce toxins, dinotoxins<span> which are capable of killing fish, so that's why this occurrence is dangerous.</span>
