The transfer of energy from one organism to the next in an ecosystem begins with a producer. A producer is an organism that prod
uces its own food. A consumer is an organism in a food chain that obtains energy from producers or other consumers; consumers may be herbivores or carnivores. Which food chain correctly describes the flow of energy in an ecosystem?
A) grass → grasshopper → fish → human
B) grasshopper → fish → human
C) human → fish → grasshopper
D) human → grasshopper → fish → grass
The answer is food chain A, as plants produce their own food using photosynthesis, therefore making them producers.
A grasshopper then eats this grass, making it a consumer as it is obtaining its energy from the producer. It is then eaten by a fish and a human. This chain accurately describe the flow of energy in an ecosystem, as it goes, producer, consumer, consumer, consumer
Let's assume that the x-axis is aligned with the incline and the positive direction is up the incline. We can then apply Newton's 2nd law as follows:
Note that the net force is zero because the block is moving with a constant speed when the angle of the incline is set at Solving for the angle, we get
