An apple falls off a tree onto the ground. which of the following best describes what eventually happens to the material that makes up the apple? a. water softens the apple and its material dissolves into the ground. b. sunlight decomposes the apple and recycles its material into the soil. c. weather conditions rot the apple until all its material disappears and no longer exists. d. microscopic organisms break down the apple and release its material into the soil and air.

D. Microscopic organisms break down the apple and release its material into the soil and air.

Explanation:

Without microscopic organisms today, everything that has died or fallen will still remain on the ground. Fungi, bacteria, and etc. play an essential role in the Earth's ecosystem by breaking down organic material.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
