Every member of a particular rodent species is found within a population living in a forest ecosystem. These rodents eat a variety of
plants and live in hardwood trees. Their population growth is limited by the amount of space they have available.
Human construction in the area is steadily reducing the habitat of the rodent species. Which of the following will most likely occur if
the species' habitat continues to be destroyed?
OA. The species will experience population growth.
OB. The limiting factor of the population will change.
OC. The population will use less resources and stay the same size.
OD. The species will eventually become extinct.

Answers

Answer:

The species will eventually become extinct.

Explanation:

If a species habitat is constantly being reduced and destroyed by a numberous number of things such as human construction, then the species will reduce and eventually go extinct. This is due to the fact that a species habitat is everything to them, it gives them a place to feel comfortable and provides them with food and other neccesities. The species would eventually become extinct is the place they need to leave which is their habitat is constantly being destroyed day by day.

How are the three stages of photosynthesis linked?

Answers

STEP ONE: Harvesting Radiant Energy

The first step of photosynthesis occurs in the chloroplasts of plant cells. Light photons are absorbed by a pigment called chlorophyll, which is abundant in the thylakoid membrane of each chloroplast. Chlorophyll appears green to the eye because it does not absorb green waves on the light spectrum. It reflects them instead, so that’s the color you see.

STAGE 2: Converting Radiant Energy

After radiant energy from sunlight is absorbed, the plant converts light energy into a usable form of chemical energy to fuel the plant’s cells

STAGE 3: Storing Radiant Energy

The last stage of the photosynthesis process is known as the Calvin-Benson cycle, in which the plant uses atmospheric carbon dioxide and water from soil to convert ATP and NADPH. The chemical reactions that make up the Calvin-Benson cycle occur in the stroma of the chloroplast.

What is Moon?

The Moon is the Earth's only natural satellite. It is the fifth largest satellite in the Solar System of the galaxy and the largest and most massive relative to the parent planet, with a diameter of about one-quarter with that of the Earth.

The most-accepted hypothesis among that of astronomers and space scientists is that the Moon was the satellite which was formed by the collision of two proto-planets, namely, the Theia, a mars-size rock and the newly born Earth planet. A substantial part of the collision debris is also fused with each other to form the Moon. Alternate theories have suggested by the scientists include the moon broke away from the Earth which is Fission theory.

Therefore, the correct option is A.

As the human population increases, how do people use land differently? A. Grasslands are used for cropland. B. Developed land is converted to wetlands. C. More land is available for animal habitats. D. Urban land becomes cropland.​

Answers

Answer:

A

Explanation:

The others don't make sense, and are the opposite of what would happen if human population increased.

As the human population increases, people tend to use land differently in various ways. One of the ways is by converting grasslands into cropland to meet the increasing demand for food. The correct option is A.

What are the different uses of land?

The conversion of grasslands into croplands results in the loss of natural habitats and biodiversity. Additionally, some developed land is being converted into wetlands to mitigate the negative impacts of urbanization on the environment.

However, this process is slow and limited due to the cost and complexity involved. Another way is by setting aside more land for animal habitats, which helps to protect endangered species and maintain ecological balance.

Lastly, as urbanization continues, there is a trend towards urban agriculture, where urban land is converted into cropland to support local food production and reduce transportation costs.

Therefore, the correct option is A.
