Photosynthetic organisms are usually

Producers

Explanation:

In an ecosystem, a species which is able to produce food for itself and others is known as producers.  

All green plants and other auto-trophic organism that consists of photosynthetic pigments have the capability to entrap sunlight and convert it into chemical energy (within the food).

Thus, all organism that have photosynthetic pigment are able to produce food and hence are known as producer.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
