Answer:
D. The energy flow is not dependent on any members of the ecosystem
Explanation:
The energy flow in an ecosystem is not dependent on any member of the ecosystem. It is the flow of energy through the food chain, energy is passed from members in one trophic level to members in another or the next trophic level. The flow of energy in an ecosystem is important because it helps in maintaining balance in ecology.

Answer: The work done by the ramp against the force of gravity is -343 J
Explanation:
Work is defined as the force that is causing the movement or displacement of an object.
Mathematically,
We know that:
where,
W = work done by the ramp = ?
m = mass of the box = 7 kg
g = acceleration due to gravity = (Negative sign appears because it is acting against the gravity)
d = displacement = 5 m
Putting values in above equation, we get:
Hence, the work done by the ramp against the force of gravity is -343 J
True
A law in science is a generalized precept to describe a body of conclusions in the form of an oral or mathematical description. Scientific laws (also known as natural laws) refer a cause and effect among the observed elements and must perpetually implement supporting the same situations.
