If you had the following food chain: Sun→grass→mouse→snake→bird of prey Which of the following would NOT happen if the snake trophic level was removed? A. The mouse population would decrease B. The bird of prey population would decrease C. The sun would stay the same D. The grass population would decrease

The mouse population decreasing won't happen when the snake trophic

level is removed.

In the trophic level below, the snake feeds on the mouse, the bird of prey

then feeds on the snakes.

Sun→grass→mouse→snake→bird of prey

However, when the snake trophic level is removed , the mouse have  fewer

predators which feeds on it. This enables the population of mouse to

increase in the ecosystem as those on top of the trophic level usually have a

smaller population to the others.

Option A

Explanation:

If the snake trophic level is removed, the following things will happen

=> The mouse population will increase because they would no more be a prey

=> The bird of prey population will decrease because their predator is no more present

=> The sun would stay the same

=> The grass population would decrease as their predator population has increased.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
