Productivity

Productivity. Energy flow through an ecosystem. ENERGY ENTERS THE ECOSYSTEM AS SUNLIGHT. Only 1-2% of the light energy falling on a tree is captured and turned into chemical energy by PHOTOSYNTHESIS The rest is reflected, or just warms up the tree as it is absorbed.

Energy flow through ecosystems

Energy flow through ecosystems. Energy flows through an ecosystem, being transferred from one organism to the next. Energy flows in one direction, obeying the law of conservation of energy. Energy cannot be created or destroyed, only changed from one form to another.
