A population that is decreasing in size will have an age-structure histogram shaped like a(n): 1) inverted pyramid, with a narro
lawyer [7]

The correct answer is - 1) inverted pyramid, with a narrow base representing a small number of young individuals.

The populations that are decreasing are usually population in countries that are highly developed. The conditions for living are excellent, the medical care on high level, life expectancy very high, but the birth rates very low.

In this type of conditions, there's smaller and smaller number of young individuals, with the middle aged population being much bigger, and the older population being constantly on the rise. This will give the age-structure histogram a reverse shape than what it is supposed to have, it will be similar in appearance like a inverted pyramid, meaning that the population is aging and that it will be constantly on a decline in the future.

How does inorganic nitrogen from the atmosphere<br> (N2) get into living systems?
lawyer [7]

Answer:

When an organism excretes or dies, nitrogen is in the form of organic nitrogen in its tissues (e.g. amino acids, DNA). During the ammonification process, many fungi and prokaryotes then break the tissue down and release inorganic Nitrogen into the atmosphere as ammonia.

Explanation:

Plants use their roots for nitrogen compounds. When they consume the seeds, animals acquire certain chemicals. When plants and livestock die, or animals excrete waste, the organic nitrogen compounds return to the soil, where microorganisms known as decomposers break down their compounds.

I NEED HELP PLEASE!!!!!!!!!!!!!!!!!!!
brilliants [131]

Answer:

66.7m/s²

Explanation:

initial velocity(V)=54m/s

Final velocity(U)=4m/s²

Time taken(t)= 0.75 seconds

Acceleration is unknown

To find the acceleration we use this formula

a=v-u/t

a=54-4/0.75

a=50/0.75

a=66.666666

since it is acceleration we use the symbol m/s² after approximating to 1 decimal place

a=66.7m/s²

rate The answer as brainliest
