What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.There are different types of ecosystems present.

Explanation:
The elements mercury and bromine are both liquids at room temperature, but mercury is considered a metal, and bromine is considered a non-metal. How can that be? Explain using properties you know of.
Answer:
At room temperature, mercury and bromine are of fluid consistency, it is because their melting or melting temperature is very low, so low that it reaches room temperature.
Compared to mercury and other metals, the more traditional metals have much higher melting temperatures.
On the other hand, bromine is not a metal, since it does not have the ability to oxidize with the presence of oxygen and also does not give up electrons.
Explanation:
Mercury in the periodic table is Hg, and bromine is Br

B. It is on the part of Earth that is experiencing nighttime.
C. It is on the part of Earth that is experiencing daylight.
D. It is on a side of Earth that faces the Moon directly.

The position of a coastal area during a low tide is: it is on a side of Earth that is perpendicular to the Moon.
What happens during low tide?Whenever the absolute bottom, or the box, arrives at a coast, the coast encounters a low tide. Envision the sea is molded like a ball pointing at the moon. The football's sharp closures address the pieces of the Earth encountering elevated tide and the ball's level sides are the pieces of the earth encountering low tide.

A student who was training for a cross-country race jogged for 1.0 hour and covered a distance of 1.5 kilometers. How much farther will the student travel if he jogs for one more hour?
Answer:
He would travel 3 kilometers.
Explanation:
Since he had already covered 1.5 kilometers in the time of 1 hour that means if he jogged for 1 more hour assuming he is going at the same pace he would've jogged 1.5 kilometers again and when you add that to the 1.5 kilometers he started with it would add up to 3 kilometers.

What do you think causes a lunar eclipse? (Use your knowledge of solar eclipses and feel free to run the Gizmo to help you.)
Moon reflects the light frim the sun, thats why we are able to see it and it shines in the night. But, we know that Earth revolves around Sun and Moon revolves around Earth. During this revolution, Earth and Moon comes in a position when Earth is in the middle of the Moon and Sun. So, it blocks the light of Sun frim reaching Moon. Hence, we see no reflection and it causes Lunar eclipse.
Answer:
A total lunar eclipse occurs when the moon and the sun are on exact opposite sides of Earth. Although the moon is in Earth's shadow, some sunlight reaches the moon. The sunlight passes through Earth's atmosphere, which causes Earth's atmosphere to filter out most of the blue light.
