LS2 (9-11) -3
Students demonstrate an understanding of equilibrium in an ecosystem by …

3a defining and giving an example of equilibrium in an ecosystem.

3b describing ways in which humans can modify ecosystems and describe and predict the potential impact (e.g. human population growth; technology; destruction of habitats; agriculture; pollution; and atmospheric changes).

3c describing ways in which natural events (e.g. floods and fires) can modify ecosystems and describe and predict the potential effects.
