How will loss of an organisms from a food chain or web affect flow of energy

1 answer:

6 0

Energy that is not used in an ecosystem is eventually lost as heat. Energy and nutrients are passed around through the food chain, when one organism eats another organism. Any energy remaining in a dead organism is consumed by decomposers. Nutrients can be cycled through an ecosystem but energy is simply lost over time.

An example of energy flow in an ecosystem would begin with the autotrophs that take energy from the sun. Herbivores then feed on the autotrophs and change the energy from the plant into energy that they can use. Carnivores subsequently feed on the herbivores and, finally, other carnivores prey on the carnivores.

Answer:

a. general stimulus origin: Proprioceptors, Exteroreceptors, Interoceptors

b. special modality of stimulus: Baroreceptors, Chemoreceptors Thermoreceptors

Explanation:

The sensory modality of stimulus refers to the aspect of a stimulus, and the sensation that is felt after a stimulus has had effect. Different sensory modalities include, temperature(thermoreceptors), light, chemicals(chemoreceptors), pressure(baroreceptors), and sound.

Stimulus origin is a classification system of receptors that indicates where a stimulus stems from. Exteroreceptors detect stimuli from the external environment and an example is the receptors found in the nasal cavity. Interoceptors are found in the internal organs and typically affect the smooth muscles of these organs. Proprioceptors are found in muscles, joints and tendons.

Answer: On a cool October morning you dressed warmly for a 10K race sponsored by a local charity, and about half way through the race you realize that you have stopped sweating in all the warm running clothes you put on and are beginning to feel faint and slightly disoriented. The most likely reason of his symptoms are that you are suffering a dehydration followed by possible hypothermia.

Explanation:

If you run dehydrated, your heart system will be struggling in poor conditions, so it will be overexposed and your heart rate will rise considerably. On the other hand, the body will not be as efficient in regulating body temperature.

Your muscles and your brain as well as the entire nervous system will not respond the same and will be demanded in conditions not suitable for your effort, therefore, the response time will fall, you may suffer cramps, headache, dizziness and even muscle spasms . If the effort is more than two hours long, you probably need more than water and you should try sports drinks also.

When running at low temperatures, a relevant factor is clothing. If we are not properly dressed to run in cold and windy conditions, we will naturally be more exposed to suffer from hypothermia. The manifestations of hypothermia are varied and include pain and tingling in the hands and feet, tremors or chills, decreased physical capacity and, in more extreme cases, alterations of consciousness.

A person who is suffering from hypothermia should wrap in dry clothes and get out of exposure to cold or wind , hydrating with warm liquids can also be useful.
