Answer: c. The Earth’s surface is responsible for a small fraction of heat radiation to space.
Explanation:
In later ages the large amount of sun's energy is reflected back by the terrestrial surface back to the space. But now due to the abundance of large concentration of greenhouse gases in the atmosphere is responsible for the absorption of thermal energy from sunlight by these gases causing the atmosphere to be hot. This is the reason of global warming. Now only small fraction of heat is radiated back to the space.

Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants .
Answer:
number 1 answer is 3.
number 2 energy is flowing upwards. ex grasshopper eats the grass, rat or whatever that is eats the grasshopper, and the hawk eats the rat. energy is going up each trophic level.
number 3. if the grass became polluted, then animals would get pollution in their bodies and at some point would die. eventually the grass would die too. primary consumers such as mouse, rabbit, grasshopper/snails would accumulate the most pollution because they directly eat the grass. whatever that is in the grass goes straight into their bodies.
Answer:
The second step in cellular respiration is called the Krebs cycle. The Krebs cycle uses pyruvic acid to create ATP, along with additional molecules like NADH, FADH2, and CO2. The NADH and FADH2 molecules are used during the final step of cellular respiration, while the CO2 is exhaled
