Answer:
Plants is the first organisms to receive Carbon as CO2, to initiate the process of photosynthesis. Through this process the plants is serving as the primary producers, and sources of carbons for other organisms.These organisms (the consumers) must feed on plants to trap Carbon, when they consume plants to derive carbohydrate(glucose),proteins and lipids.

Answer:
they are important because they recycle nutrients, making them available for other organisms
Explanation:
they are natures recyclers and return nutrients back into the soil
Answer;
-Positive charge
Prior to the arrival of a signal from a presynaptic input, the post-synaptic membrane is polar with a greater relative positive charge to the ECF
Explanation;
-Neurons talk to each other across synapses. In somatic neurons, an action potential arrives at the synapse causing synaptic vesicles to fuse with the presynaptic membrane. The pre-synaptic membrane releases acetyl choline via exocytosis into the extracellular of the synaptic cleft.
-The ACh diffuses across the cleft and binds to the ligand-regulated sodium channels. Activated sodium channels allow a rapid diffusion down its electrochemical gradient towards the ICF. The movement of positive charges to the ICT causes the relative charge across the membrane to become positive on the inner surface.
