Greetings!

Organisms in an ecosystem can be affected by humans in many ways. As well known, we have the most control over our environment. Therefore, we affect it the most as well.

We affect other organisms by many of the things we do. For instance, throwing trash on the ground outside may affect a near by living creature. That creature may eat the trash, and that can badly affect them.

See what I mean?

Hope this helps!

Answer from: Quest

the displacement produced by the body.

the amount of force subjected to the body.

the angle between the direction of force and displacement

Answer from: Quest

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 -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [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.
