About This Chapter

The Interaction Among Organisms in the Ecosystem chapter of this AP Environmental Science Homework Help course helps students complete their interaction among organisms in the ecosystem homework and earn better grades. This homework help resource uses simple and fun videos that are about five minutes long.

How it works:

  • Identify which concepts are covered on your interaction among organisms in the ecosystem homework.
  • Find videos on those topics within this chapter.
  • Watch fun videos, pausing and reviewing as needed.
  • Complete sample problems and get instant feedback.
  • Finish your interaction among organisms in the ecosystem homework with ease!

Topics from your homework you'll be able to complete:

  • Interspecific competition
  • Predator/prey interactions
  • Symbiotic relationships
  • Density, survivorship and life histories of populations
  • Carrying capacity, migration and dispersion
  • Colonization and island biogeography

Interspecific Competition, Competitive Exclusion & Niche Differentiation

1. Interspecific Competition, Competitive Exclusion & Niche Differentiation

What happens when two similar species that consume the same resources occupy the same space? Interspecific competition, that's what! Watch our video lesson to learn about the outcomes of this ecological battle.

Predator/Prey Interactions, Camouflage, Mimicry & Warning Coloration

2. Predator/Prey Interactions, Camouflage, Mimicry & Warning Coloration

You probably know that skunks can be quite stinky, bees sting and monarch butterflies are pretty, but do you know why? This lesson will introduce you to the reasons why some animals look or act the way they do and how these things relate to the predator/prey relationship.

Symbiotic Relationships: Mutualism, Commensalism & Parasitism

3. Symbiotic Relationships: Mutualism, Commensalism & Parasitism

If your cat or dog has ever had fleas, you've witnessed symbiosis in action. In this lesson, learn the many types of symbiosis in biology, and how these relationships can have a positive, negative, or neutral effect on the individual species.

Populations: Density, Survivorship and Life Histories

4. Populations: Density, Survivorship and Life Histories

Have you ever wondered how biologists determine the populations of animals in a particular geographic area? Watch this video lesson to find out, and discover how scientists look at the survivorship and life histories of many different species.

Carrying Capacity, Migration & Dispersion

5. Carrying Capacity, Migration & Dispersion

Have you ever wondered why some types of birds fly south in the winter or why some animals form territories? Watch this video to learn about a species' maximum growth capabilities, the way its members group themselves and why they might migrate to new locations every year.

Dispersal, Colonization, and Island Biogeography

6. Dispersal, Colonization, and Island Biogeography

Have you ever gone in your backyard and discovered a wild raspberry bush that has never been there before? How did it get there? Why is there only one bush year after year? In this lesson, you'll study how plant and animal species colonize in new areas through dispersal and immigration and how some species thrive in a new area while others fail.

Conservation Biology, Habitat Fragmentation, and Metapopulations

7. Conservation Biology, Habitat Fragmentation, and Metapopulations

It's becoming harder to conserve large, unbroken tracts of wilderness. Is there another way for conservation biologists to ensure the survival of a species? In this lesson, you'll learn about habitat fragmentation and metapopulations.

How Introduced and Invasive Species Alter Ecological Balance

8. How Introduced and Invasive Species Alter Ecological Balance

What happens to your block when a new neighbor moves in? Something changes, right? Now think about that on an ecological scale: what happens to an environment when a new SPECIES moves in?

What Are Keystone Species? - Definition & Examples

9. What Are Keystone Species? - Definition & Examples

Understand the definition and importance of a keystone species in an ecosystem. Read about some examples of keystone species that show how necessary they are for a healthy environment.
