Answer:
A Carbon Dioxide ( CO2)
Explanation:
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.
Overconsumption – situation where resource use has outpaced the sustainable capacity of the ecosystem. ...
Overpopulation – too many people for the planet to sustain. ...
Acid rain.
Biodiversity loss.
Deforestation.

Answer:
Bonding.
Explanation:
Bonding prevents complex or macro-molecules from spontaneously and rapidly degrading into atoms because force of attraction present between atoms. These bonds are very strong which is only breakable when there is high amount energy is supplied so we can conclude that bonding between atoms of complex molecules are responsible for their intact structure and prevent rapid degrading into atoms.
Answer:
Cornea
Explanation:
The first part of eye through which light enters into the eyes is cornea. Cornea comes in front of the pupil and iris and is made up of transparent layer. It is a curved structure just like a normal glass lenses and hence is able to focus light on retina. It also protects the eyes. Cornea along with anterior chamber is responsible for 67 percent of the optical power of eye and sends the light towards the pupil.
