The correct answer is A) Chlorophyll absorbs sunlight energy for photosynthesis.
Well, if one of the major species, that a certain animal eat disappeared, then it would effect the animal that ate it. Then, if that animal doesnt get fed, or eat the right things, it will die, and so will the animal that eats it. Its like the domino effect, if one goes down, so does everything else.

The viscosity of water is the thickness of water (it might also be considered the stickiness when talking about other fluids). Water has many properties, and the viscosity of water influences in many of them. We can take the surface tension of a liquid as an example. The more viscous a substance is, higher will the surface tension be and vice versa since there will be a higher and lower attraction between molecules respectively.
→ The surface tension of water is something really important since it contributes in many ways to the environment and if you think about it, if the water was a little less viscous, there wouldn't be water since the viscosity of water makes it resistant to evaporation to a certain degree.
