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.

5-8 Sentences on: "How Does The Availability Of Resources In Ecosystems Impact Ecosystems?"

Changing out natural resources in our environment can affect the whole entire ecosystem.  Ecosystems can change throughout time but the change may or may not affect the ecosystems.  But according to research, if the change is too fast the whole ecosystem can be destroyed.  An imbalanced or damaged ecosystem can lead to problems.  Certain resources play an important role such as sunlight and water, we need resources to survive and can also help living creatures.  These resources impact animals, plants, and insects/bugs.

The following table shows the distance from the sun of some unknown planets of equal mass.

W 1.5 AU
X 0.723 AU

Which of the following best explains which planet revolves at a faster speed?
A.) Planet X, because the sun pulls it with a greater force.
B.) Planet W, because the sun pulls it with a greater force.
C.) Planet W, because the gravitational force is weakened by distance.
D.) Planet X, because the gravitational force is strengthened by distance.

Answers

I think that the correct answer is A

Answer:

Option D.) Planet X, because the gravitational force is strengthened by distance.

Explanation:

As we know from Kepler's law , the planets that are closer to the sun move at a faster rate in comparison to those planets that are far because of high gravitational force.

According to the question,

both planets have equal mass. Plant W is at 1.5 AU and planet X is at 0.723 AU distance from the sun.

So, planet X revolves at a faster speed because it's shorter distance from the sum as comparison to planet W, strengthened the gravitational field.

Thus, Option D is the correct answer.
