Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

1. Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

Matter is constantly cycled between living and nonliving parts of the environment. Processes like photosynthesis and nitrogen fixation allow the carbon and nitrogen cycles to regenerate needed substances by recycling Earth's atoms.

Phosphorus Cycle: Steps, Definition & Diagram

2. Phosphorus Cycle: Steps, Definition & Diagram

Phosphorus is an essential element to all living organisms. It is part of our DNA and RNA, and it forms the molecule ATP, which gives all living things energy. This lesson explains its importance and will walk you through the steps of the phosphorus cycle.

Biosphere: Definition & Explanation

3. Biosphere: Definition & Explanation

All organisms, from the tiniest bacterium to the largest blue whale, need a place to live. The 'place on Earth's surface where life dwells' is called the biosphere. But what does this really mean? In this lesson, we'll look at the definition of the biosphere and examine how human activity is changing this important part of our planet.

Food Chains, Trophic Levels and Energy Flow in an Ecosystem

4. Food Chains, Trophic Levels and Energy Flow in an Ecosystem

In this lesson, you'll learn about food chains, food webs, and the different roles that organisms play in an ecosystem. You'll also learn about how energy flows through an ecosystem.

Ecology Producer: Definition & Explanation

5. Ecology Producer: Definition & Explanation

This lesson will define what a producer is and what its role is in an ecosystem. It will also discuss the different kinds of producers and give some specific examples of them.

Ecology Consumer: Definition & Explanation

6. Ecology Consumer: Definition & Explanation

This lesson will discuss the role of consumers in an ecosystem. It will describe their place in a food chain and how they interact with other organisms. Specific types of consumers will be presented.

What is a Decomposer? - Definition & Examples

7. 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.
