Answer: Density
Explanation: Recall Archimedes Principle. There are two forces acting an object submerged in a liquid: the force of gravity and the (opposite directed) force of buoyancy. The buoyancy is proportional to the mass of the liquid displaced by the submerged part of the object.
Density is the ratio of mass to volume. Therefore if the density of the submerged object is higher than that of the displaced liquid, the net force will point in the direction of the gravity (object will sink). In the opposite case, the net force will point in the direction of the buoyant force (upward) and the object will float.
When plants die they become food for the decomposer for example Lettuce, If all the Lettuce in someones field died the decomposer would get its nutriets and make the soil stronger, so if you plant more Lettuce and it survives the Consumer would get to eat the lettuce. Hope this helped! :)

Answer:
-5m/s
Explanation:
Since
acceleration=final velocity-initial velocity/time
2.5m/s^2=20m/s- initial velocity/10s
2.5m/s^2×10s= 20m/s -initial velocity
25m/s=20m/s - initial velocity
Initial velocity=20m/s-25m/s
= -5m/s
