marusya05 [52]

Answer:

D. Gross primary productivity is the total amount of solar energy captured by producers through photosynthesis over time.

Explanation:

The gross primary productivity of an ecosystem represents the rate at which the producers of the system capture the solar energy so that they can perform the process of photosynthesis. Therefore, GPP is the total amount of photosynthetic energy captured per unit area over a given time period. Producers consume the part of the GPP for their own respiration and maintenance. Therefore, gross primary productivity is the sum total of the growth of producers per unit area per unit time and the energy used by them for respiration.

A preganglionic sympathetic fiber traveling to the abdomen would synapse in which structures?
juin [17]

Answer:

Answered below.

Explanation:

The nerve fibres of the autonomic nervous system that connects the ganglia to the the central nervous system are called preganglionic fibres. They are divided into sympathetic preganglionic fibres and parasympathetic preganglionic fibres and both have acetylcholine as their neurotransmitter.

The sympathetic preganglionic is shorter compared to the parasympathetic preganglionic fibres. They originate from the hypothalamus and brainstem and project to the ganglia non the spinal cord. A ganglion is a cluster of nerves outside the central nervous system.

The preganglionic sympathetic fibres originating from T1-T2 innervate the cervical ganglion which innervates the muscles of the pupils (dilators).

The postganglionic fibres originating from the preganglionic fibres of T11-L3 passes through splenic, celiac and mesenteric ganglia to innervate the kidneys and renal vessels.
