The nutrients get to the cells in a flatworms solid acoelomate body by diffusion process.

<h2>When too walk your dog you are using energy from the sunlight to power this activity</h2>
Explanation:
The ultimate source of energy in the ecosystem is the sun. When we take our dog for a walk, we are utilizing energy stored in our body that we obtained food. We must have obtained that from either plants or animals. The animal in turn must have obtained its food from plant. Plants are the organisms in the food chain who can convert the energy from the sun into the chemical energy. So, we can say that when we walk our dog we use energy from the sunlight to power this activity.
