About This Chapter
Ecosystems, Competition & Adaptations - Chapter Summary
Our expert instructors walk you through topics related to adaptations, competition and ecosystems in this engaging chapter. You'll watch short videos on habitats, ecological niches, food chains and interspecific competition, among other topics. After finishing this chapter, you should be able to do the following:
- Provide examples of symbiotic relationships
- Outline trophic levels, energy flow and food chains in an ecosystem
- Detail the climate, plants and animals in an open ocean biome
- Identify types of forest animals and their habitats
- Define intraspecific competition and provide examples
- Discuss competitive exclusion, niche differentiation and interspecific competition
- Explain adaptations for desert, tropical rainforest and grassland animals

1. Ecosystems, Habitats and Ecological Niches
Check out this video lesson to understand the many complex aspects of an ecosystem. See how animals live in habitats and survive amongst their surroundings.
2. Symbiotic Relationship: Definition & Examples
Symbiotic relationships are a special type of interaction between species. Sometimes beneficial, sometimes harmful, these relationships are essential to many organisms and ecosystems, and they provide a balance that can only be achieved by working together.
3. 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.
4. Open Ocean Biome: Plants, Animals, Climate & Definition
Seventy-one percent of the surface of our planet is covered by the oceans. It should be no surprise that the open ocean biome is the largest biome on Earth. In this lesson, we will investigate the properties and inhabitants of the open ocean biome.
5. Animals of the Forest: Types & Habitats
In this lesson, you'll be learning about animals of the forest. By the end of this lesson, you'll understand which animals and habitats exist in rainforests, temperate forests and the cold taiga.
6. Intraspecific Competition: Example & Definition
How do members of the same species share resources? There's an ongoing struggle among individuals of the same species called intraspecific competition, and this competition is one way that nature controls how large a population gets.
7. 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.
8. Desert Animal Adaptations
Desert animals have adapted to living in an extreme environment (with higher temperatures and dryness) through the use of both physical and behavior specializations. Read this lesson to learn how these specializations help them survive.
9. Tropical Rainforest Animal Adaptations
Tropical rainforests present challenging conditions to the animals that live there. In this lesson, we'll explore several of the diverse adaptations animals have developed in order to survive and thrive in the tropical rainforest.
10. Grassland Animal Adaptations
Across the planet, there are numerous grasslands, each with its own unique animal inhabitants. How do the animals in these grassland environments survive and adapt? In this lesson, we'll explore grassland animal adaptations, the behavioral and physiological traits that help animals survive.
