Energy in ecosystems must be continuously supplied by the sun as the warmth from the sun allows plants to grow plus photosynthesis depends on the sun's energy also. Animals also depend on the sun for warmth to survive (or else hibernate). Also, the sun powers the water cycle, the carbon cycle and the nitrogen cycle
<span>In order to react to the stimulus and catalyze the reaction necessary for the desired outcome, enzyme require a process in which they bind with the substrates in the given experiment, which will then allow the enzymes to undergo the process they are attempting to implement.</span>

I thought I already answered this but anyways, the answer is A. Zebras will live and graze in herds. When a predator spooks the herd the zebras run as one. That ways it confuses let's say the lion because they see in black and white. To them they see racing stripes so it's hard for them to decide which zebra to take down. If running together backfires, the zebras will stand their ground and protect the weaker and younger zebras by kicking and biting the lions. Hope this helps!
The effect is usally positive because it can help them adapt to their environment
