Environmental Science | Fun Learning Quest for Kids

You're analyzing a forest ecosystem where removing a single species of sea otter causes the entire kelp forest to collapse. What concept from environmental science does this best illustrate, and why should you care when designing complex systems like your own side hustle?

In a grassland ecosystem, you measure 10,000 kcal of solar energy captured by producers. Assuming a typical trophic efficiency of 10%, how much energy is available to a tertiary consumer? What does this tell you about the feasibility of long food chains in your college project planning?

You're studying a lake that experienced a massive algal bloom after farmers applied nitrogen-rich fertilizer upstream. Which biogeochemical cycle is most directly involved, and what key principle does this illustrate about human impacts on Earth's systems?
