Animals are <u>consumers</u> and hence they depend on other organisms (plants and other animals) for their food.
Velocity change increases as the force increases.
Even though this question is incomplete, but we can approach it from the stand point of Newton's second law of motion.
According to this law, force is directly proportional to change in velocity.
F = m(v - u)/t
F = force applied
m = mass of the body
v = final velocity of the body
u = initial velocity of the body
t = time taken
This means that velocity change increases as force increases.
The answer is C) extrusive igneous. This rock starts as magma, so you know it must be a type of igneous<span> rock. The question tells you that the rock forms when it is cooled by the water, so you know it is formed outside of the Earth's interior, therefore making it extrusive igneous rock.
