Ecosystems
Explore how living things interact with each other and their environment across different habitats. These Ecosystems quizzes cover energy flow, food webs, nutrient cycles, and biodiversity, helping you connect key ecology terms to real-world examples.
Quizzes
Ecological succession after disturbances
Explore how ecosystems rebuild after fires, floods, storms, and human impacts. This quiz covers primary vs. secondary succession, pioneer species, and the shifting roles of soil, nutrients, and competition over time. Choose your preferred difficulty and question count, then learn through clear, scenario-based questions.
Energy flow in food webs
Trace how energy moves through ecosystems, from producers to top predators and decomposers. This quiz focuses on trophic levels, food chains vs. food webs, and what happens to energy at each transfer. Choose your question count and difficulty, then answer each multiple-choice item at your own pace with no timer.
Nutrient cycles: carbon, nitrogen, and phosphorus
Trace how carbon, nitrogen, and phosphorus move through ecosystems and shape life on Earth. This mixed-difficulty quiz checks your understanding of reservoirs, fluxes, and human impacts across land, water, and atmosphere. Choose your preferred question count and difficulty, then learn from each result as you go.

What you’ll practice
These quizzes help you review how ecosystems function, from producers and consumers to decomposers, habitats, and ecological niches.
You’ll also practice interpreting relationships like predation, competition, and symbiosis, plus how changes in one part of a system affect the whole.
How the quizzes work
Each question is multiple-choice with 4 options, and there’s no timer—so you can focus on accuracy and understanding rather than speed.
Quiz length and difficulty vary, letting you start with core definitions and move toward more applied questions about ecosystem dynamics and human impacts.
Key topics you’ll see
- Food chains, food webs, and trophic levels
- Energy flow and ecological pyramids
- Biomes, habitats, and limiting factors
- Nutrient cycles (carbon, nitrogen, water)
- Biodiversity, stability, and succession
- Human impacts such as pollution and habitat loss
Quick ecosystem context
Ecosystems can be tiny (like a puddle) or vast (like a rainforest), but they all rely on energy entering—usually from the sun—and nutrients being recycled through living and non-living components. After major disturbances, many ecosystems follow predictable patterns of succession as species gradually change over time.
