Question

The flow of energy through living systems can be modeled as food chains, food webs, or energy

pyramids. The energy organisms need to live and grow first enters the ecosystem when which of the
following occurs?

Answer 1

Photosynthesis

Step-by-step explanation:

The energy organisms need to live and grow first enters the ecosystem through the process of photosynthesis when green plants manufacture their food.

• Photosynthesis is the process in which green plants manufactures their foods in the presence of sunlight(solar energy) using water and carbon dioxide.
• The sunlight synthesizes energy rich compounds in this process.
• There is a transformation of solar energy to chemical energy.
• Different organisms rely on this chemical energy for their own energy needs.
