Which of the following food chains shows one way that energy moves through an ocean ecosystem? a.) fish > plankton > whale > squid b.) squid > whale > fish > plankton c.) plankton > squid > fish > whale d.) whale > fish > plankton > squid

plankton > squid > fish > whale are the following food chains shows one way that energy moves through an ocean ecosystem.

c)plankton>squid>fish>whale

Explanation:

Energy always move up in an ecosystem according to the ten percent law.a food chain is made up of producers and consumers. producers are at the base of every food chain and above the producer levels come the consumer levels. The given question mentions aquatic ecosystem where plankton is the major producer that directly derive energy from sunlight.

In a terrestrial ecosystem plants are the major producers. in the given food chain plankton, the producer is consumed by squid which is the primary consumer. The squid is then eaten by fish which is the secondary consumer here and it is finally consumed by whale which is the tertiary consumer.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
