A. A steep slope has a higher rate of soil erosion than a rate of soil formation.
<h3><u>Answer;</u></h3>
A). Organic compounds would not be available for use by autotrophs.
<h3><u>Explanation;</u></h3>
- The stability of an ecosystem depends on the actions of the decomposers.
- Therefore, if there were no decomposers in an ecosystem then, wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.
- The carbon and nitrogen necessary to build organic compounds, and then cells, allowing an organism to grow, would be insufficient. Other nutrients necessary for an organism to function properly would also not be sufficient.
Answer:
In order to perceive a stimulus, that stimulus has to meet or exceed the absolute threshold; in order to detect a change in that stimulus, the stimulus has to meet or exceed the differential threshold.
Explanation:
The absolute threshold is the minimum intensity of energy that is required to cause a sensation in a person, that is, the minimum or maximum maginitude that a stimulus must have in order to be captured. The absolute threshold defines our perceptual limits and varies depending on the individual. The differential threshold (Just Noticeable Difference, JND) refers to the minimum intensity at which a stimulus must be increased so that we notice a change in that stimulus, that is, it's the increase that is necessary in the intensity of the stimulus so that the person perceives a modification of the same.
Weber's law states that the stronger the initial stimulus, the greater is the additional intensity necessary for the second stimulus to be perceived as different.
The tropical plants remove carbon from the atmosphere. In a sense they are the only reason global warming hasn't taken over. We can use them to stablize the climate if we can keep them alive and not chop them all down. This is important because the more trees we have the less the climate will change. If the climate keeps changing, the temperture will get hotter, species will die, and all the icecaps will melt
This is not the exact answer but I hope it will help you understand more
