Answer:
C
Explanation:
Large distances are easier to express in AU than in km. Hope this helps :)
Answer: Amphibians and water animals.
Explanation:
This is due to the inefficiencies of passing energy from one energy level to the next. Studies have shown that only 10% of energy is passed from a lower trophic level to the next higher level as biomass. The rest is lost in inefficiencies such as heat. This is why the graphical model of energy flow in a community is shaped like a pyramid with the lowest energy levels at the bottom and highest energy levels at the top.
Radiation is the energy transfer in the light from space from the sun to the solar collector.
<u>Explanation:</u>
On the earth itself the solar collector is situated, here energy must travel from sun to the Earth through vacuum, but energy cannot be transmitted through vacuum by either conduction like molecular collision or convection like fluid movement due to difference in densities, as both of the process need medium. Thus energy from sun to the Earth is traveled through radiation carrying electromagnetic waves, many of these are light waves. Thus energy transfer in the light from space from the sun to the solar collector is processed through radiation.
