<u>Answer</u>: D. calcium chloride
<em>Calcium chloride molecules can be ruled out as the mystery molecule</em>
<u>Explanation:</u>
<em>Artificial membranes are also called as the synthetic membranes.</em> It is created synthetically for the <em>special separation purpose in the laboratory. </em>
It is used to separate large molecules like <em>solid particles and big biological molecules like protein, DNA. </em>
They are produced from organic materials. <em>Calcium chloride contains the chloride ion and calcium ion,</em> as the chloride ion easily passes the artificial membrane so we can term <em>calcium chloride as the mystery membrane that passes the artificial membrane easily.</em>
The producers are the main source of the food production in the ecosystem. The producers are the organism, which convert the energy from the sunlight into the chemical energy. The consumers use this chemical energy for carrying out the metabolic processes in their body.
Without producers, the consumers cannot obtain their energy. Hence, the ecosystem without any producer would not survive.
