Study Guide

Decomposers

Decomposers (saprotrophs) are organisms such as bacteria and fungi that break down the organic matter in the dead bodies of plants and animals into simple nutrients.

First Law of Motion

Also known as the law of inertia, Newton's first law of motion states that An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Neutron

A neutron is a subatomic particle found in the nucleus of an atom. It is neutral as it carries no electric charge.

Outer Planets

In contrast to the solid terrestrial planets, the outer planets (Jupiter, Saturn, Uranus, and Neptune) consist of hydrogen and helium gas and water.

Respiration

The respiratory system manages respiration which is the process by which blood cells absorb oxygen and eliminate carbon dioxide.
