What type of organism would most likely be found in place of the question marks?

ruslelena [56]

Answer:

Decomposers

Explanation:

The diagram in this question illustrates a food web, which is a series of interlinked food chains in an ecosystem. In a food chain as depicted in the image, the arrows point to the organism that feeds on another organism. For example, an arrow is pointing from Idaho fescue to an Elk meaning that the elk will feed on that plant.

Different trophic levels constituting organisms exists in the food web including; producers (plants), primary consumers, secondary consumers, tertiary consumers etc. However, as observed in the image, a general arrow carrying along all the organism is pointing towards the organism in the question mark. This organism is called DECOMPOSER.

A decomposer, usually a microorganism, is an organism that breaks down dead organisms and returns the nutrient to the soil for recycling. All organisms in the food web will eventually die and when they do, they'll be decomposed by a decomposer. This is why the arrow pointing towards the decomposers include all organisms.

When the vasomotor center of our brain wishes to increase blood pressure, it increases ____________ signals causing ______.

dlinn [17]

When the vasomotor center of our brain wishes to increase blood pressure, it increases the heart rate signals causing The greater contraction of the heart causes more blood vessels to constrict, increasing the blood vessels' resistance.

By speeding the heartbeat, making the heart beat harder, and constricting some blood vessels, the sympathetic nervous system increases blood pressure. This will enhance the vessels' resistance.

What controls blood pressure by the vasomotor center?

The vasomotor center modifies the tone of the vascular smooth muscle. Both the local and systemic blood pressure are impacted by this. The vasomotor center produces increased sympathetic tone when blood pressure lowers. This causes an increase in blood pressure.

How is blood pressure regulated?

The autonomic nervous system has short-term control over blood pressure (ANS). Baroreceptors are capable of detecting changes in blood pressure. These are situated in the carotid sinus and aortic arch. High arterial pressure causes the blood vessel wall to stretch, activating the baroreceptors.

What systems regulate peripheral resistance in the vasomotor center?

The vasomotor center in the tunica media regulates smooth muscle contraction or vessel tone. Circulating output is impacted by changes in peripheral resistance, pressure, and flow. The majority of these neurons are in charge of causing sympathetic neurons to release the neurotransmitter norepinephrine.
