<span>The competitive exclusion principle states that when
two organisms attempt to fill the same niche, one will exclude the other from
the ecosystem. Research partitioning is an adaptive evolution that when species
are have similar preys, they compete with each other and one species is deemed
to extinct in the process however if two species are of different preys, then
they can exist with one another. To exist with one another, organisms belonging
to a same species either compete for the resources or divide it amongst
themselves. This concept is important because it helps in diversified ecology,
where animals and plants of the same species co-exist and creates a beauty with
nature.</span>
The power dissipated by the LED is 20 Watts and the work done for 1 hour 15 minutes is 56.25 kJ.
<h3>What is electrical power?</h3>
Electrical power is the rate at which electrical work is done.
- Electrical power = voltage × current
The LED is 75% efficient means that 75% of power dissipated by the LED is converted to light.
Total power dissipated = 5 × 2.5 = 12.5 Watts
- Work done = power × time (in seconds)
Work done = 12.5 × (1 × 3600 + 15 × 60)
Work done = 56250 J = 56.25 kJ
Therefore, the power dissipated by the LED is 20 Watts and the work done for 1 hour 15 minutes is 56.25 kJ.
