how has the growing human population and the increased use of resources affected Earth systems?

Answers

Answer: The growth of human population has increased the use of resources dramatically throughout the years. In the year of 1960, there were only an estimated 3 billion people in the entire world. In the 2000's  there was a huge and odd curve in human population. Since then, the human population has been getting bigger and bigger ever since. In today's time in which we almost have 8 billion people in the world, people are starting to wonder if we are going to have enough resources to actually support life on Earth. This makes people's insane theory's about federal actions to decline human population something to take into consideration. For example, many people think that the government made Cov/id-19 in a lab in order to make a decline in human population to support the world easier. Earth is now being affected by the use of these resources that billion's of humans use every day due to pollution. We can't make every single human in the world stop pollution, but just by you helping you make a big difference. As earth's population gets bigger and bigger we need to start considering to make a difference.

There are two forms of ER that are commonly found:-Rough ER, which has  ribosomes embedded within its structure, giving it a rough appearanceSmooth ER, which lacks these ribosomes and hence appears smooth.

The endoplasmic reticulum (ER) plays an essential role in protein synthesis, folding, modification, and intracellular transport.

Explain why you you think the population of each organism changed the way it did

Answers

Answer:

If populations don't change very much over time, the ecosystem is in equilibrium .Populations decrease at higher levels of the food chain because they require more energy from other organisms.

The given question is seems it lacks some information, however, on the best knowledge of the provided information the correct answer would:

The change in the population of each organism is due to the evolution process that takes place because of changes in the environment in order to survive.

The changes in the genetic material of a particular population occur over a long period of time, the cause of this change is the process called evolution.

Evolution exhibits the adaptations that took place in organisms to their environmental changes that lead to altered genes, novel characteristics, and new species.changes in genetic variability and changes in allele frequencies over timenatural selection is the cause of evolution that occurs in organisms that are more likely to survive and reproducerandom fluctuations in allele frequencies in a population called genetic drift

Thus, the correct answer is - evolution.
