Explore several ecological relationships with The Amoeba Sisters! Ecological relationships discussed include predation, competition, and symbiotic relationships (parasitism, mutualism, and commensalism). Table of Contents: Intro 00:00...

Paul Andersen explains how populations interact in an ecosystem. The symbiosis of several populations is based on effects that may be neutral, positive, or negative. Interactions like mutualism, commensalism and parasitism are...

When we hear the term symbiosis, we tend to think about a simple partnership between two biological organisms. But in many cases, there are more than two parties involved and it's way more complicated.

Interactions between species are what define ecological communities, and community ecology studies these interactions anywhere they take place. Although interspecies interactions are mostly competitive, competition is pretty dangerous,...

An ecosystem is complex community of living organisms. The living things depend on each other and the environment they're in, from the tiniest bug to the biggest animal. Relationships between organisms are a crucial part of ecosystems....

Symbiosis is a close and evolved interaction between species, which can be obligate (necessary for survival) or facultative (optional). It includes various types: mutualism (both benefit), commensalism (one benefits, the other is...

With a better understanding of population ecology, we are ready to zoom out and look at community ecology, which involves interactions between species, as well as landscape ecology, which will broaden our understanding of ecosystems. How...

Symbiosis is relationship where two different species co-exist and at least one derives benefit from the other. The name for an organism with a symbiotic relationship is a symbiont. Let's look at some examples of symbiotic relationships.

This section covers the relationship between organisms and their environment. It also covers the Levels of Organization and symbiotic relationships.
