Question 1 (1 point) student knows that only about 10 percent of the enersy available at one trophic level transfers to the next trophic level. As went drawn
energy pyramid that contains seven trophic levels. Starting from at the bottom level, he labels the trophie levels in the following marar
producers, first level consumers, second level consumers, third level consumers, fourth level consumers, fifth level consumers, and level
consumers. His teacher examines his work and says that his enerxy pyramid is not accurate What is wrong with the drawn
it contains many levels
he did not number the levels correctly
it does not use arrows to show the flow of energy
it mixes the order of consumers

Question 2 (1 point)
Algae makes up the base of marine food webs, which statement best describes how a marine food web would be affected in the long term #
ocean temperatures became too cool for algae to survive?
O a
only primary consumers would lose their food source
only the algae population would decrease
all consumers would be negatively impacted
all consumers would find other sources of food

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

level 4 to level 2 : ))
