As the sun shines on Earth, plants use its energy to complete the process of photosynthesis. Energy is transformed during the process into chemical energy in the form of sugars, such as carbohydrates. However, the energy available for top consumers is much less than that produced by autotrophs. Why is this so?
There are fewer top consumers than producers in a food web.
There are more producers than consumers in the food web.
Primary and secondary consumers compete for food.
Most of the energy is used for life's processes.

Sally and sue were investigating the topic of friction in science. they used a small car and a ramp as seen in the picture to test what they were learning. they knew that they slipped easily on waxed floors but not on carpet, so they decided to change the material on the surface of the ramp to see what happened. they planned to use glass, carpet, aluminum foil, and sandpaper and run the car down the ramp over each surface. what would be the best research question to guide the girls' experiment? a) does the amount of surface area affect the friction on the moving car? b) will the car travel fastest on the glass surface? c) how does the angle of the ramp affect the speed of the car? d)do rougher surfaces tend to create more friction than smooth surfaces?
