Plants roots display positive gravitropism which means they grow in the direction of gravity
Answer:
D
Explanation:
When a substance moves from low to high concentration it is moving against its concentration gradient, which requires more energy.
A. It depends on where it is moving, not the substance
OB. This is describing diffusion
OC. Does not require energy, it is passive transport through a semi-permeable membrane
Energy flows from one animal or plant eating or getting eaten to the next anima above it. As for your translation, the crickets are eating the grass then are getting eaten by the secondary consumers and finally getting fed to the largest consumer and every time you go up in the food chain more and more energy is being passed on.
