An important part of any ecosystem are the biotic (living) and abiotic (non-living) factors. This video explore what each of them are, and how to identify them. To learn more about ecosystems in general check out our other video on...

Paul Andersen differentiates between biotic and abiotic factors. He explains how both abiotic and biotic factors can affect organisms at the level of the cell, the population and even the ecosystem. The complexities of biofilms,...

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...

The video discusses the different abiotic components that affect grassland ecosystems. The video highlights the importance of water, light, temperature, and soil type in the grassland ecosystem. It also mentions the impact of wind on...

This program explores the major features of earth's amazing biosphere. Students are introduced to the biotic and abiotic components found in an ecosystem. Footage from throughout the world illustrates how ecosystems can change over time....

This video introduces the viewer to biomes, ecosystems and habitats. With a clear explanation of what makes them different and how they are connected. Biotic and Abiotic factors are explained and discussed.

Paul Andersen reviews the major components of the homeostasis. He explains how organisms respond to abiotic and biotic factors in their environment with feedback loops. He shows how responses can be behavioral or physiological.

Paul Andersen explains how ecosystems interact with biotic and abiotic factors. He explains and gives examples of food chains and food webs. He shows how limiting factors eventually leads to logistic growth. Real data from Yellowstone...

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...

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...

Explain ecosystem, environment its biotic and abiotic components, the levels of ecological hierarchy and the branches of ecology.

This 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...

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...

In this video, we learn about the components of an ecosystem, including biotic (living) and abiotic (non-living) factors. We also learn about the different types of biotic components, including producers, consumers, and decomposers.

What's the next wave of the technology revolution? How will it affect business and society?

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...
