Acell that can not produce its own energy, the energy must be consumed.

The correct answer is heterotrophic cell.

Explanation:

A cell which is not able to produce its own food as a source of energy is called heterotrophic cell. An autotrophic cell produce its own source of energy through photosynthesis process like cells of plants and algae or by chemosynthesis like archaebacteria.

Heterotrophic cells are present in heterotrophic organism and these organisms are dependent on others for energy consumption.  

So the organism made up of autotrophic cells are produces because produce its own energy and heterotrophs are consumers because they consume producers or other consumers to obtain energy.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
