You are given 3 objects - a cube, a sphere and a cylinder made of different materials. If you are told that ONLY ONE OF THEM floats on water, which one would it be?

The cylinder will float on water due to lower density than water.

The cylinder will float on water if its density is lower than water or in other words if the cylinder is less denser than water, then it will float on the water while on the other hand, if the density of cylinder is more than water, the cylinder will sink.

Those materials will float on water which has more volume as compared to its mass and we now that density is inversely proportional to volume so we can conclude that cylinder will float on water due to lower density than water.

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
