Types of Matter & Energy Changes in an Ecosystem

1. Types of Matter & Energy Changes in an Ecosystem

Ecosystems are a constant flow of matter and energy from one place to another. In this lesson, we will discuss some of the important energy and matter cycles that take place within and between ecosystems.

What Is the Carbon Cycle? - Diagram, Process & Definition

2. What Is the Carbon Cycle? - Diagram, Process & Definition

The carbon cycle is the process by which carbon moves from the atmosphere into the Earth and its organisms and then back again. Gain a deeper understanding of how the carbon cycle works in this lesson.

The Water Cycle: Precipitation, Condensation, and Evaporation

3. The Water Cycle: Precipitation, Condensation, and Evaporation

This lesson discusses the processes water takes as it moves around the Earth in the water cycle. You'll get an in-depth look at condensation, precipitation, and evaporation.

What Are Detritivores? - Definition & Examples

4. What Are Detritivores? - Definition & Examples

In this lesson, we will investigate detritivores. These organisms play a crucial role in all ecosystems by utilizing their unique diet to clean up decaying organic matter. We will see examples of them and learn of the benefits they provide to the world.

What is a Decomposer? - Definition & Examples

5. What is a Decomposer? - Definition & Examples

Decomposers are an often overlooked part of the natural world, but their job is an important one. Learn what decomposers are, what role they have in the environment and how people use them.
