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.
In the simple example of the oxygen cycle shown above, you can see how oxygen is used and cycled by plants and animals. Plants are the main creators of oxygen in the atmosphere through the process of photosynthesis. Here the tree uses sunlight and carbon dioxide to produce energy and releases oxygen. The giraffe breathes in the oxygen and then breathes out carbon dioxide. The plant can then use this carbon dioxide and the cycle is complete.
