How does the way that matter flows through an ecosystem differ from the way that energy flows?

Physics
1 answer:
drek231 [11]3 years ago
3 0

Answer:

Matter can be recycled while energy cannot be recycled in an ecosystem.

Explanation:

Energy is lost in form of heat from one organism to another. The major energy in an ecosystem is from the sun (solar energy) which is taken by the producers. Once the sun stops generating energy, life will be difficult. Unlike the sun, matter can be recycled. Living things need non living things to survive. Matter can be 'nutrient' (which is non living). Nutrients are needed for life and growth. Nutrients include water, oxygen, carbon etc. An ecosystem nutrient cycle shows that decomposes are vital. Decomposers release nutrients when they break down dead organisms. These nutrients released by Decomposers are taken in by plants through the roots. The nutrients pass from producers (plants) to primary consumer (herbivores) when they feed on plants and then to higher levels consumers when they feed and digest the lower levels consumers and the producers. When they (the living things) grow and die, the nutrient cycle begins again.

<u><em>A moving charge experiences a force as it moves close to a magnetic field present in a region.</em></u>

Explanation:

A charged particle when moves near a magnetic field is forced to move in a circular path. If there is a straight moving charged particle enters the region of the magnetic field, it's path is changed from straight path to the curved path.

The motion of the charged path inside or near the magnetic field will be a circular path and this circular path is due to the force experienced by the charged particle in the magnetic field.

The force experienced by the a charged particle as it moves near the magnetic field is termed as the Lorentz force. The expression for the Lorentz force experienced by the charged particle in the magnetic field is given by:

\boxed{F_m=Q(\overrightarrow{v}\times\overrightarrow{B})}

Here, F_m is the magnetic force, Q is the amount of charge, \overrightarrow{v} is the velocity vector and \overrightarrow{B} is the magnetic field intensity in the region.

Thus, <u><em>A moving charge experiences a force as it moves close to a magnetic field present in a region.</em></u>

a cyclist applies a constant forward force of 20 N to maintain a velocity 2.5 m/s. how much power does the cyclist deliver?
forsale [732]

The power exerted by the cyclist is determined as 50 W.

<h3>Average power exerted by the cyclist</h3>

The power exerted by the cyclist is calculated as follows;

P = FV

where;

  • F is the applied force
  • V is velocity

P = 20 x 2.5

P = 50 W

Thus, the power exerted by the cyclist is determined as 50 W.

How is high temperature achieved by concave mirror?
tensa zangetsu [6.8K]

A concave mirror is used in the design of solar furnaces because they converge the parallel sunrays at a point. This helps to increase the temperature of the furnace.
