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.
Scientists do not know exactly how much oxygen comes from the ocean and how much comes from the trees on land. Some scientists believe that more than one-half of the oxygen comes from the ocean while other scientists say only about one-third of the oxygen comes from the ocean.
