Answer:

Chemoautotrophs

Explanation:

Autotrophs are groups of organisms that are capable of manufacturing their own food (organic molecules) through the fixation of carbon dioxide. There are two types of autotrophs:

  • <em>Photoautotrophs fix carbon dioxide by using light as the energy for driving the process.</em>
  • <em> </em><em>Chemoautotrophs f</em><em>ix carbon dioxide by  using energy from the oxidation of inorganic molecules such as magnesium, or sulfur.</em>

climate

Changes in the composition of the atmosphere have caused gradual changes in earth's <u>climate</u> throughout history, causing changes in plant and animal life that contributed to mass extinctions.

The following are some of the reasons:

  • UV light
  • climate
  • pollutants
  • hydrofluorocarbons

heat

  • The surface of the Earth warms up as sunlight strikes it.
  • Surface-emitted infrared light is absorbed in the atmosphere and transformed into heat.
  • The temperature close to the surface rises as a result of this heat being trapped in the atmosphere.
<h3>UV light:</h3>
  • indirect impacts of climate change on UV radiation from the surface.
  • By changing the concentrations of ozone, UV-absorbing tropospheric gases, aerosols, and clouds in the atmosphere, climate change may have indirectly affected UV radiation levels in the past.
  • These influences are probably going to persist in the future.
<h3>climate:</h3>
  • People are at risk from food and water shortages, greater flooding, high heat, an increase in disease, and economic loss due to climate change.
  • Conflict and human migration are potential outcomes.
  • Climate change is the top hazard to world health in the twenty-first century, according to the World Health Organization (WHO).
<h3>pollutants:</h3>
  • these are also resulting in the increase of temperature of the Earth and is also damaging ozone layer.
