A pyramid to show  how much biomass or energy that is at each trophic level.
Example: A rabbit eats a plant and only gets 10% of the 100% energy.

A heterotroph is an organism getting energy from a more complex organism. It can't make it's own food.

Us humans are heterotrophs, because we need to find other food rather than make it.

it starts out in the air then it moves into the soil and the bacteria fixes it. then it goes through the other bacteria, and then it goes to the plant or if there's too much it will go back in the air where it started.

Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. An example of Primary Succession is the formation of new islands.

Examples include : Lichen , Trees, Grasses , Ferns, M0sses
