Answer:
First trophic level
Explanation:
The energy distribution among the trophic levels varies greatly. In general, we can say that the lower the trophic level is, the more energy it has, and the higher the trophic level is, the less energy it has.
This same principle goes for the population size in the trophic levels as well. The lower the trophic level is, the higher the population is, the higher the trophic level, the lower the population is.
These two things are connected. The populations in the lower trophic levels are higher because there is much more energy, while the populations in the higher trophic levels have lower populations because the energy available is much smaller.
The first trophic level has the highest populations by far, and the reason behind it is that the organisms of this trophic level are actually able to produce their own food, thus energy.

Answer:
The direction of rivers are usually expressed with respect to the directions we are familiar with: North, South, East or West.
A river has an origin, usually at a higher latitude and ends at the sea or ocean or a large water body. Gravity is the driving force for river flow. Hence, we gauge the ‘direction’ the water is going to flow for any river.
If we were going to get more technical, flow in rivers and streams are measured for their streamflow, which is the amount of water passing through some infinitesmal volume, i.e a point over time. The velocity of the water is determined using acoustic/Doppler based instruments, which will give the local direction of the flow of the river at the measured point along with the velocity.
Hope the answer helps!
