Answer:
If there wasn't a lot of organisms and energy in the productive part of the triangle, then there wouldn't be a lot of third level organisms. The energy piramid would be a lot smaller then what it is here, and maybe if the energy source was low then there might not be such a vast varity of animals in the ecosystem.

Answer:
a. movement can occur both upward and downward in the plant
Explanation:
The phloem loading causes the accumulation of sugars in the sieved elements generating a negative solute potential (quedas), with a drop in water potential (ψw), so water enters the sieved elements increasing the turgor pressure (ψp). With the discharge of phloem in the drain occurs lower concentration of sugars in the screened elements, increases the solute potential, becoming positive, thus the phloem water potential increases and thus the water leaves the conducting vessel. In the specific case of sugar movement in the phloem, it can be stated that this movement can occur both up and down in the plant.
It is released through nitrogen - fixing bacteria
Answer:
When elements and compounds that are dissolved in water leave a solution, crystallization occurs. Minerals form in this way underground & in bodies of water.
Explanation: so either underground or water
The founder effect<span> occurs when a portion of the </span>population<span> (i.e. "founders") separates from the old </span>population<span> to start a new </span>population<span> with different allele frequencies. </span>Small populations<span> are </span>more<span> susceptible </span>genetic drift<span> than large</span>populations<span>, whose larger numbers can buffer the </span>population<span> against chance events.
