Which kingdom is composed of multicellular autotrophs? a) animal b) fungi c) plant d) protist

 C) Plant

Explanation:

An autotrophic organism is the one which is capable of producing it's food by utilizing the light energy from sun by photosynthesis (photoautotrophs) or utilize the energy from the available inorganic chemicals to make organic substances which they use as food (chemoautotrophs).

Plants are multicellular autotrophs which produce their own food by the process of photosynthesis. The chlorophyll pigment present in the leaves of the plants absorb the light energy from sun in the presence of which the reactants such as carbon dioxide and water are converted into carbohydrates and oxygen.  

to figure the total magnification of an image that you are viewing through the microscope is really quite simple. to get the total magnification take the power of the objective (4x, 10x, 40x) and multiply by the power of the eyepiece, (usually 10x)
