A system is a group of parts that can be considered one unit. Storm systems, ecosystems, and our bodies are natural systems. Car

s and houses are human-made systems. Choose an example of a system, and analyze the energy flow through the system. Describe in detail how energy enters the system, how energy changes form while in the system, and how energy leaves the system.

An ecosystem is simply a collection of communities of plants, animals, and microbes interacting together and with their physical environments.

<h3>Energy flow in an ecosystem</h3>

Energy enters the ecosystem through a group of living organisms known as the producers. the producers are mainly the green plants that are capable of photosynthesizing.

Photosynthesis converts solar radiation from the sun to chemical energy in green plants. Another group of organisms in the ecosystem, the primary consumers, feed directly on the producers and as such, are able to gain some energy from them.

The secondary consumers obtain their own energy by feeding on primary consumers. Tertiary consumers feed on the secondary consumers for their own energy and the food chain goes on and on.

Only about 10% of the available energy in one trophic level goes to the next trophic level. The rest of the energy is lost as heat to the surroundings. Thus, the producers have the highest energy in the ecosystem while organisms at the top of the food chain have the lowest energy.

What are some of the ways that people can Reduce their use of fossil fuels?
alukav5142 [94]

Answer:

By using renewable energy sources.

Explanation:

You need to satisfy a quota of energy for (whatever country you live in). People do this by using the cheapest way of producing the most energy, the most efficient. Sounds great right? Wrong! It stuffs our atmosphere with harmful gasses like carbon dioxide. You can reduce the use of these fossil fuels by using renewable energy sources such as windmills, watermills, and most notable, solar panels!

The attraction which exists between carbon diozide molecules in solid carbon dioxide is due to
Kobotan [32]

Answer:

Van der waal's  force of attraction

Explanation:

Van der waal's  force of attraction

Forces of Van der Waals involve attraction and repulsion among atoms, particles, and surfaces as well as many other intermolecular forces. These vary from covalent and ionic bonding in that they are caused by similarities in surrounding particle fluctuating polarizations (a result of quantum dynamics).

Use the drop-down menus to complete each sentence.
Ipatiy [6.2K]

Explanation:

Elements that belong to same group contains same number of valence electrons. Hence, they tend to show similar chemical properties.

When we move across a period then number of electrons get added to the same shell. As a result, there will be no increase in size of elements.

Also, metals are the elements that belong to group 1, 2 and d-block elements are also known as metals. Metallic character of elements decreases when we move left to right in a periodic table.

As most reactive metals are placed on the left side of periodic table.

Since, size of elements increases on moving down the group. So, an element is able to easily lose its valence electrons because of less force of attraction between its nucleus and valence electrons.

As a result, there will be increase in reactivity of metals on moving down the group.

Thus, we can conclude that given sentences are as follows.

  • Elements in the same group have the same number of valence electrons.
  • Elements in the same period have the same number of electron shells.
  • Metallic elements become less reactive as you move left to right in a period.
  • Metallic elements become more reactive as you move top to bottom in a group.
