Answer is c. If one essential nutrient within an ecosystem runs out, primary productivity will be limited
According to Vitousek et al., 2010, nutrient limitation defined as meaningful additions of an essential element in biologically available forms which increases the rate of primary productivity or increase in the biomass in an ecosystem. Alternately, nutrient limitation may also explained as when the supply of one essential nutrient of the ecosystem runs out the primary productivity of the plants will be limited.
Species change over time. -The mechanism that produces the change is natural selection: the differential survival and reproduction of individuals based on variation in their traits. Natural selection acts on individuals but individuals do not evolve; their descendants do.
Initia Velocity(u) :- 15m/s
Acceleration(a) :- 4m/s2
Time Taken(t) :- 50 Seconds
{ok a formula is there —->>> s = ut + 1/2 at2(it is ‘t’ square)….. now we will write like this and yeah don’t write this}
We Know,
s = ut + 1/2 at2
s = (15*50 + 1/2 *4*50*50)m
s= (750 + 5000)m
s = 5750 m
Therefore distance traveled is 5750 meters.
Hopefully this helps
Due to collisions between particles in the spinning cloud, the solar nebula begins to flatten. The particles in the gas cloud first have all different speeds in different directions. As they start colliding with each other, their final velocity is the average of the two initial velocities before collision.
