Answer 1

Answer:

a)The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells. The sun heats the earth's surface and the Earth heats the air above it, causing wind.

b)yes, zebra population go down because zebra only feed in the grass on but when the grass is not then how they will eat if they will not eat it will automatically

c)Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. A food chain can usually sustain no more than six energy transfers before all the energy is used up died
