📋 What it is
Ecosystems have carrying capacity, niches, and succession — deeper rules that shape communities.
🗣️ Coach says
Beyond food webs are deeper rules. Carrying capacity is the max population a place can support. A niche is a species’ “job” in the community. Succession is how an ecosystem changes over time — bare rock → moss → shrubs → forest. These concepts explain WHY ecosystems look the way they do.
🧠 Memory hook
Carrying capacity = the limit. Niche = the job. Succession = change over time.

What do you call a sneaky decomposer?
A fun-gus in disguise!
😲 Whoa!
After a volcanic eruption leaves bare rock, it can take CENTURIES for succession to rebuild a full forest — nature is patient.
✅ Quick check: What is an ecosystem’s “carrying capacity”?
Say your answer out loud first — then reveal.
The maximum population of a species the environment can support with its food, water, and space.
Carrying capacity caps population growth based on available resources.

Think of a fish tank. What limits how many fish it can hold? That limit is its carrying capacity.
