Answer:
The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll, while the products are glucose (sugar), oxygen and water.
Explanation:
Water and carbon dioxide are reactants for photosynthesis. Chlorophyll captures sun's light energy and then plants chemically combine this with water and carbon dioxide to make glucose (sugar) and oxygen.
Answer:
1. primary cause of human-created carbon emissions = burning fossil fuels
2. destroys natural carbon sinks leading to more carbon dioxide in the air = deforestation
3. emits methane from decomposing matter = waste disposal in landfills
Explanation:
1. "Fossil fuels" are <em>nonrenewable resources</em> that are considered essential for the operation of many factories and industries. <em>Burning them accounts for most of the carbon emissions on Earth</em>, and this leads to<em> "global warming."</em>
2. "Forests" are considered "carbon sinks" because they have a role of <u><em>absorbing the carbon dioxide in the atmosphere</em></u>. Cutting down the trees (deforestation) makes forests barren. It then leads to more carbon dioxide in the air.
3.<em> Waste disposals in landfills contribute to the amount of methane that is released into the atmosphere.</em> Methane is considered a <em><u>potent greenhouse gas</u></em> that affects people's health.
Explanation:
<u>Ecological footprint:</u>
<h3>Is a Measure the area required by an individual, population or activity of biologically produced land and water to produce all the resources it consumes and absorb the waste it generates, using prevailing technology and resource management practices. Hope this helps and have a great day! Good luck </h3>
