No it will not work. You can not control the heat of the water which needs to be around 78F. At night when the light is off the fish will be chilled. During the day when the light is on the surface of the water could be very hot and the bottom cold. Also the heat from the light globe will dry the air which will make it bad for the Betta to breathe. Heater/thermostats are a cheap item as is a thermometer, an air pump and a filter. They are all necessary items if you wish to keep tropical fish alive and healthy.
I don't think you need to warm up their bowl. As long as the bowl is room temperature, you might need to put him in front of a window. But with a little bit of shade, you wouldn't want to fry your fish!

You don't need one if there is light in the room from a window or some other source unless you have live plants
no
Any producer of heat can produce light by reaching enough energy
IF YOU HAVE A MICROSCOPE THAT DOES NOT HAVE AN INTERNAL LIGHT SOURCE, YOU WILL HAVE TO USE THE EXTERNAL LIGHT SOURCE THAT IS PROVIDED IN THE CABINET WITH THE MICROSCOPE.
light
Unless they are blind cave fish, which have no eyes, fish need light. You want a light om an aquarium so you can see the fish to best advantage. It does not need to be a special aquarium light, if a room is light enough for you to move around in, it is light enough for the fish, regardless of temperature. A weird thing may happen if the light comes from the side. Fish orientate themselves to light more than gravity. With strong side lighting they will swim tilted, sometimes almost completely on there sides.
no. sometimes planets are bright enough that light reflects off of them
Betta fish need to be kept in slightly warmer water, about 80 F. The water on top of the container is often warmer, especially if you have it close to a light source. It may be that the water is too cold.
aquarium light
Yes a light is healthy for a Betta, they need lights for warmth (the light will heat up the water) And Bettas get sick easily so without warm water they will get ill and lose there color and become a gray color.. Which is not pretty.
Yes :0
A canopy is the cover that goes on top of an aquarium. Often times it will have a light built into it
