In this video Paul Andersen explains how biodiversity can be measured through genetic, species, or ecosystem variety on the planet. Species diversity is increased through speciation and decrease through extinction. The mechanism for...

Paul Andersen explains how ecosystems change over time. He starts by explaining how global climate change will impacts ecosystems around the planet. He then discusses how continental drift created climatic changes that impacted mammal...

Today we're going to take a closer look at ecosystems -- which are communities of living organisms in an area interacting with their environment -- and how this relationship between the amount of energy a place receives and the movement...

Around the world, living things have managed to build truly extraordinary ecosystems in some of the last places you would think to look. Understanding these ecosystems can help us protect or repair them, and it can also help us...

In this video Paul Andersen explains how ecosystems respond to disruptions. Disruptions can cause changes in the number and variety of organisms. It can also lead to migration, extinction or even speciation. Ecosystems that have a...

In this video Paul Andersen explains the important relationships that exist in ecosystems. He starts by delineating between organisms and their environment. He explains how food webs can be used to show energy and matter flow in a...

Regardless of the habitat type, method of management, or end goal, ecosystem management plays a large part in modern society. Without effective ecosystem management, we would have much less access to the resources that we use for our...

Ecosystems!

Learn about different types of ecosystems. This video is a great introduction to types of ecosystems. An ecosystem is a community of interacting organisms and their environment. This is a great way for children to...

Our planet is blessed with many types of ecosystems, including terrestrial, marine, freshwater, forest, and grassland. An ecosystem is a dynamic community that comprises living organisms, such as microorganisms, plants, and animals, as...

Our planet is blessed with many types of ecosystems, including terrestrial, marine, freshwater, forest, and grassland. An ecosystem is a dynamic community that comprises living organisms, such as microorganisms, plants, and animals, as...

An ecosystem is a complete community of living organisms and the nonliving materials of their surroundings. This includes plants, animals, microorganisms and their environment, such as soil, rocks, and minerals. An Ecosystem also...

Discover how climate, water, soil, plants and animals function as one and depend on each other in distinct ecosystems, which can range from a pond to an ocean, a tree to a vast forest. Biology - Ecosystems - Learning Points. An ecosystem...

New ReviewThis video describes some of the ways that living and nonliving things in ecosystems interact. Beautiful, colorful videos help illustrate these interactions in ecosystems such as deserts, grasslands, and wetlands. Specific emphasis is...

NASA is working alongside Conservation International and the Liberian Government through the Environmental Protection Agency (EPA) to pilot an innovative and replicable approach to more accurately map ecosystems to...

This video reviews the concepts covered in the Ecosystem Dynamics series. The video explores the features of ecosystems, the concept of biodiversity, and energy flow in ecosystems. Ecosystem Dynamics part 9/10

This video provides an introduction to the concept of abiotic components in ecosystems, using a grassland in Iowa as an example. The video highlights the importance of abiotic components and how they play a crucial role in sustaining the...

What happens when non-living factors in an ecosystem are altered, such as rainfall or air quality? Biology - Ecosystems - Learning Points. An ecosystem is a living system interacting with its physical habitat. Changes in biotic and...

New Review“Global Aquatic Ecosystems” examines the diversity of freshwater ecosystems and marine ecosystems, discussing their varying temperatures, depths, salinities, and biodiversity.

Ecosystems are large, often highly complex areas of our environment. In this video we learn how abiotic and biotic factors interact with one another in a ecosystem, how trophic levels work, and how various factors in an ecosystem lead to...

This video is answering the question of what is an ecosystem.

The video discusses the concept of energy flow in an ecosystem, highlighting the complex relationships between producers, consumers, and decomposers. A simplified diagram of a forest ecosystem is shown, illustrating the...

The video explores the concept of ecosystems and their different environments on Earth. It features various examples of ecosystems, including a tidal pool, a salt marsh, and a grassland. Ecosystem Dynamics part 3/10

This video explores five fun facts about ecosystems.

Permaculture instructor Andrew Millison explains the process for repairing a degraded ecosystem. We begin with the metrics for assessing ecosystem health, and then go over the steps to triggering biological activity and ecological...
