D.Elements continuously cycle between the physical environment and living organisms.
Ecosystem is encompassing all the life on earth in the physical environment that supports it. An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system. <span> </span>

Answer:
During photosynthesis the oxygen is released into the atmosphere through
All photosynthetic eukaryotic cells contain chloroplasts that use the radiant energy of sunlight to convert carbon dioxide and water into carbohydrates. As a byproduct of photosynthesis, oxygen gas is also released into the atmosphere through tiny openings in the leaves called stomata.
Explanation:
The correct answer is option (D) store and release neurotransmitters.
The function of synaptic vesicles inside the axon terminals is to store and release the neurotransmitters. A synapse refers to the junction between the two neurons which transmit the nerve impulses by the diffusion of a neurotransmitter. Synaptic vesicles ar important for the transmission or the conduction of the nerve impulses as they store and release the neurotransmitters.
These neurotransmitters are the chemicals that transmit an impulse between two neurons or a neuromuscular junction. A neurotransmitter is released by the synaptic vesicle of one neuron into a region between the two neurons called the synapatic cleft. From here, it reaches the neurtransmitter receptors present on the target neuron, thus conducting the impulse. Examples of neurotransmitters include the epinephrine, histamine, acetylcholine and others.
