An autotroph is an organism that can produce its own food.
Answer:
The treelike fibers that receive information and send it toward the neuron's cell body are called Dendrite
Explanation:
Dendrite:- They are tree like projections generally the extension of nerve cell which helps in the transmission of nerve impulses or electrochemical stimulation from one neuron to another. It is also known as dendrons. For neurons to become active they need some action potential, these action potentials are received in the form of nerve impulses or electrochemical stimulation by dendrite and is been stored in the cell body, or soma, of the neuron. Dendrites are covered by synapses (Structure that permit neural transmission).
I'm not entirely sure what you mean, but a fit animal is one that is able to out-compete with other animals in its ecosystem. It possesses some kind of advantage, which makes it easier to compete with others for food, water, shelter, and mates. Due to these qualities, the animal is obviously able to live for a good deal of time and have a greater chance of producing viable offspring.
