Question

choose the correct answer. the graphic is a grassland in africa. what best describes it? a closed system with regards to energy; a closed system with regards to matter; an open system with regards to energy and matter

Explanation:

A grassland ecosystem (like the African grassland) exchanges energy (e.g., solar energy, heat) and matter (e.g., nutrients, water, organisms moving in/out) with its surroundings. Closed systems don't exchange energy or matter, but grasslands do both, so it's an open system for energy and matter.

Answer:

an open system with regards to energy and matter
