Unless something like bison or cows keeps the grass from growing, the forest will start growing back.

What is the main source of energy that powers most ecosystems on earth?
The sun Added: This is definitely true. Sunlight affects all surface and shallow water ecosystems. All though the sun provides us with a primary source of energy for almost all of earth's ecosystems, with proof of greenery from photosynthesis; this is not the case in such areas like the land of the Sahara desert and the Southwest climates of the USA. The lack of abundant water is another factor.
How a bacterium is able to control its diverse and complex metabolic activities even though it lacks a brain?
Bacterium is able to control its metabolic activities even though it does not have a brain because it is automatic engrained into the bacterium to survive. They can change their protein and enzymes so they can adapt to the changing environment.
Is artificial selection or selective breeding a good analogy for the selection that occurs in nature?
It is possible to have artificial selection in nature because of naturally occurring changes in the environment. These changes can greatly modify the organisms in question.
Explain how the internal state of balance is maintained in the body?
An internal state of balance is maintained by a term called "homeostasis". In order for the body to be balanced, it must maintain five functions. (1) atmospheric pressure (2) nutrients (3) oxygen (4) water (5) body temperature. Homeostasis describes the body's ability to maintain relatively stable in internal conditions even though the outside world is constantly changing. For example, when a persons body temperature drops, the hypothalamus (located in the brain: responsible for maintaining body temperature) sends a signal that the body is too cold and the hypothalamus will regulate the body temperature to a normal range. Any kind of homeostatic imbalance in the body could trigger severe illnesses.
Can men lactate?
"Though the mammary glands of human males cannot produce milk automatically under natural conditions, with appropriate hormonal stimulus---mimicking that which human females produce naturally when they become pregnant and give birth---they can" In summary, yes, it is possible, but not under normal natural circumstances. - wikipedia However, this is only or humans, several other males of mammalian species, can lactate, such as several bat species and goats.
An object traveling in a circle is accelerating because it is constantly changing?
An object traveling in circular motion is constantly changing because its 'direction' is constantly changing due to the circular motion. The speed may be unchanging say, 5 miles per hour but the direction may be going form East to North to West to South and then back to East, say in counter clockwise motion.
When is the sun at an angle?
At all times. The measure of the angle is constantly changing, though. It can be at any angle depending on: the location on Earth, the day of the year, and the time of day.
Acceleration is an increase of speed during a given interval of time?
No. It is the change in velocity (not speed) during a given interval of time. It can be an increase or a decrease although a decrease is also called a deceleration.The distinction between velocity and speed can best be illustrated by an object going round in a circle at a constant speed. It is changing direction all the time so that its velocity is constantly changing. It is constantly accelerating even though it is travelling at constant speed.
How many dollars is 312000 euros?
If you are talking US Dollars then as of Jan 25th, 2014 - €312,000 is $426,722. The exchange rate is constantly changing though and you can always check via Google by just making this search '312000 eur to usd'
Is a car on a circular track has also constant velocity?
Yes, IF it maintains constant speed on the track. The academic definition of velocity is speed and the associated direction, a vector. A car traveling in a circle is constantly changing direction. However, most people, including physicists when they are not writing textbooks, treat velocity and speed as interchangable such that a car going a constant speed on a circular track would be considered to have a constant velocity even though the direction in which it is traveling is constantly changing.
Why did Lewis Morris sign the Declaration of Independence?
He was for independence though he constantly abstained
Are stars constantly moving?
Yes. They are at such great distances though, that this is hardly noticeable.
What place is Texas Rangers in?

Which two actinides occur naturally?
Uranium and Plutonium are the only elements from the Actinides series that occur naturally on Earth, though they are rare.
Is aluminum Sulfate organic or naturally occurring?
Aluminium sulphate, Al2(SO4)3 is not organic but an inorganic salt. It occurs naturally, though it is rare.
How fast do you travel to get to Jupiter?
The distance between Jupiter and Earth is constantly changing, so there is no definitive answer for this question.
Who is the leader of the Syrian government?
