<span>-is recycled in ... flow through</span><span>
On a global scale, energy flows through ecosystems whereas chemical elements are recycle in ecosystems. So the answer is the third option.
Energy flows through the ecosystem. Most energy comes from sunlight and it is transformed into chemical energy by autotrophs. When they are consumed by heterotrophs the energy is passed on, until it dissipates as heat.

Chemical elements like carbon and nitrogen, on the other hand, are cycled between biotic and abiotic factors in an ecosystem. This is not possible for energy. These chemical elements come from abiotic factors like the air, light and soil. They are incorporated in the biomass of the photosynthetic organisms and are consumed by other organisms. They are changed back into their inorganic form when the organism dies and are broken down by decomposers and the cycle goes on. So they are constantly being recycled.
In summary, energy needs a continuous source to be able to maintain and sustain the energy flow in the ecosystem. Chemical elements, on the other hand, are just recycled through processes between abiotic factors and biotic factors. </span>
Answer:
d. Researchers said the flu shot reduced the risk of developing the flu when it actually didn't.
Explanation:
A Type I Error can be defined as the error that occurs in hypothesis when a researcher rejects the opposite of his hypothesis even though the opposite of his hypothesis is correct or true. Type I Error can also be called a False positive.
In the question above an hypothesis was carried out by researchers to determine if getting a flu shot would reduce the risk of developing a flu.
The truth is " Getting a flu shot actually reduces the risk of developing a flu"
But the researcher hypothesis test result that would result in a Type I error says "Researchers said the flu shot reduced the risk of developing the flu when it actually didn't".
This result of hypothesis test of the researchers above is a rejection of truth (the truth is an opposite of the researchers hypothesis test) and it would result in a Type I Error.
To maintain a stable environment.
Hope this helps!

Answer: Option D
Explanation:
When osmolarity of unrine increases, this makes the body to produce antidiuretic hormone(ADH). The kidney then keeps more water and ingest more water inside the body and this result in a highly concentrated urine. But if there is low osmolarity of urine, anti diuretic hormone is not produced, water is not ingested, the urine and blood will remain diluted.
Answer:If a teenager has low self asteem , they are more likely to participate in risky behaviour. This could be for many reasons such as feeling the need to fit in and be like others , and as you feel bad about yourself you feel more pressured to show off to people to make you feel better about yourself as others are taking interest in you x
