A few things about Hughesnet that you need to understand... The $55 is the price for the connection, taxes and fees are not included, nor is the modem lease fee. Buying your own equipment is generally not a good idea, it costs a fortune, and if it ever fails, your out even more money. You are better paying the $10 monthly lease fee.
Plants use carbon dioxide and sunlight to create energy in a process called photosynthesis. As a byproduct of photosynthesis, oxygen is released. Most of the oxygen from photosynthesis comes from the ocean. Some bacteria, known as cyanobacteria or blue-green algae, also create oxygen through photosynthesis.
Interestingly, although green plants contribute much of the oxygen in the air we breathe, phytoplankton and cyanobacteria in the world's oceans are thought to produce between one-third and one-half of atmospheric oxygen on Earth. Photosynthetic cells contain special pigments that absorb light energy.
