Answer:
How do nutrients move through an environment? What drives the movement of nutrients?
My answer 6b: Nutrients are often transported across the environment by migrating from the physical environment into living creatures and then being recycled back into the physical environment. For example, an animal could receive nutrition by eating plants. To stay alive, the animal uses the chemical energy gained from the food. When the animal dies, the nutrients in its body return to the soil and are re-absorbed by plants. The transport of nutrients in the ecosystem is driven by nutrient cycles.
Sensory neurons receive impulses and carry them from the sense organs to the spinal cord or brain. Interneurons connect sensory and motor neurons and interpret the impulse. Motor neurons carry impulses from the brain and spinal cord to muscles or glands. Draw and label the structure of a typical nerve cell.
