Identify the living and non-living parts of the nitrogen cycle.

Answers

Nitrogen cycle is repeating cycle

The nitrogen cycle is a cyclical process in which nitrogen moves through both living and non-living things, including the atmosphere, soil, water, plants, animals, and bacteria.

What is nitrogen cycle?

The Nitrogen Cycle is a biogeochemical process in which nitrogen is converted into various forms before passing from the atmosphere to the soil to the organism and back into the atmosphere.

Nitrogen fixation, nitrification, denitrification, decay, and putrefaction are some of the processes involved.

Nitrogen fixation, nitrification, and denitrification are the three major steps in the nitrogen cycle.

It is a biosphere cycle that includes the atmosphere, hydrosphere, and lithosphere. Nitrogen can be found in a variety of reservoirs.

The nitrogen cycle is a cyclical methodology in which nitrogen moves through both living and nonliving systems such as the atmosphere, soil, water, plants, animals, as well as bacteria.

The structure of jupiter and sun mostly made up of hydrogen and helium.

What are the characteristics of hydrogen and helium?

Hydrogen and helium are the lightest elements in the periodic table. They exist as gases at room temperature and are the two most common elements in the universe, with hydrogen making up about 75% of all matter.

It will form a mixture of two of the lightest gases known. Though Hydrogen atoms (H) turn into hydrogen molecules (H2) to form a very reactive, flammable, and explosive hydrogen gas, Helium (He) atoms form an inert gas.

The key difference between hydrogen and helium is that hydrogen is a diatomic gas, while helium is a monatomic gas. Helium has a fully filled s orbital (1s2), but in hydrogen, there is only one electron, so it is unstable.

Do protists (amoeba, Euglena, Paramecium) use similar structures to move? Explain.

Answers

Answer:

Most protists move with the help of flagella, pseudopods, or cilia. Some protists, like the one-celled amoeba and paramecium, feed on other organisms. Others, such as the one-celled euglena or the many-celled algae, make their food by photosynthesis. ... Theyuse pseudopods to move away from bright light or to trap food.

Within the protist kingdom, organisms have developed very similar structures that are used to move around the environment.

The protist kingdom is primarily comprised of very small, single-celled organisms. Among the vast number of organisms that make up this kingdom are algae and amoebas. Over the course of history, these organisms have evolved very similar means of mobility.

Within the protist kingdom, most of the organisms move with one of the structures:

CiliaPseudopodiaFlagella

These three structures used by protist to move are very similar in that are all structural extensions on the exterior limit of a cell. Though clear differences exist in the number or other uses of these extensions, it is clear that all of the members of this kingdom have evolved similar means of mobility.
