Answer:
D. Water is the most abundant atom in Earth’s atmosphere.
Explanation:
An atom can be defined as the smallest particle of an element (e.g., oxygen, hydrogen, etc). Water is a molecule (H2O) because its atoms are connected by molecular bonds (i.e., water is not an atom). Water is the most abundant molecule on the Earth's surface which covers more than 70 percent of the world's surface. A water molecule contains one oxygen (O) and two hydrogen (H2) atoms which are connected by covalent bonds. Water is also a compound known as a diatomic molecule, i.e., a molecule composed of two atoms of the same type.

Secondary succession means the regrowth in an ecosystem that already existed, after a disaster such as floods, fire, and etcetera. This is as opposed to primary succession whereby a new ecosystem is developed where none existed initially, usually on a new substrate.
Explanation:
In the picture on the left looks like a picture of a forest decimated by fire. On the right is a picture of the grass growing on the forest floor. This probably due to the fact that the canopy of the forest was destroyed in the fire enabling sunlight to penetrate to the floe of the forest supporting vegetation growth. This secondary succession. The grass acts like pioneer species. Later, the forest floor will be colonized by perennial, and then woody plants and the ecosystem will be back to its normal state.
