A small, rocky island is home to a community of organisms. They include birds, insects, lichen, moss, shrubs, and small plants. Flooding during a storm damages the ecosystem, except for the lichen and moss. Predict how the ecosystem changes immediately during the flood, after the floodwater drains, and over time.

Letter a, because when there are unlike charges they will always attract to each other.

Answer:   [a]:   "slate" .

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
