<span><em><u>SOMATIC NERVOUS SYSTEM</u></em>
The neuron, a cell that composes the nervous system. For example a brain, an organ composed of thousands of neural fibers and glial cells that performs many important organismic functions.
Neurons are specialised cells that have dendrites, axons and terminal buttons that sends and receives stimuli from the environment and transduces it into a meaningful information and understand the complexities which the brain now functions. </span>
From the sensory organ received by the sensory neuron the message is sent to the brain and then back to the motor neuron to the muscle or organ responsible.
Pioneer species are found in area's undergoing secondary succession. For example ecosystems being established by: reducing a fire, deforestation; which quickly colonize open spaces supported by vegetation.
1). A good example for mutualism is People and plants. We provide plants Carbon dioxide. Plants provide us Oxygen
2).Biome is where you have your tundras, Rain forests, Deserts, etc. then you have to give 3 characteristics like temperature, precipitation levels, soil type, etc.
I will have to get to question 3 later since im in class but ill give you the answer to that one. its easy
