The correct order of the flow of energy is c) sun to grass to cow to human.
This sequence represents the transfer of energy through an ecosystem. Let me break it down for you:
- Sun: The sun is the primary source of energy for life on Earth. It provides the light and warmth necessary for plants to grow.
- Grass: Plants, such as grass, convert sunlight into chemical energy through the process of photosynthesis. This is how they store energy from the sun.
- Cow: When cows eat the grass, they obtain the energy stored in the plant material. This process is a vital part of the food chain.
- Human: Finally, when humans consume the meat or milk from cows, they access the energy that originally came from the sun and was stored in the grass, passed through the cow, and then to them.
This flow of energy is fundamental to understanding ecological relationships and food webs. Each step in this sequence represents a transfer of energy that sustains different forms of life.
