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.

Answers

Answer:

Threatened Species: A threatened species is a species at risk but not yet endangered. California sea otters were classififed as a threatened species. Laws were passed to protect the otters and now they have increased their population size.

Invasive Species: One of the main causes of extinction and endangered species is the introduction of an exotic species. New exotic species are called invasive species. Invasive species can disrupt food chains, carry disease, prey on native species directly, and out-compete native species for limited resources, like food.

Extinction: If a population decreases too much in numbers, they disappear. Extinct species mean that the species has died out and no individuals left. An example of extinction: New Zealand was once home to a bird called the Giant Moa. Humans settled as their population increased the Moa population decreased. The species is now extinct.

Resources affect populations
Living and nonliving things are both found within the same ecosystem. The living things require the non living things for survival.

Limiting Factors
Environmental factors, such as the amount of water, food, sunlight and temperature available, are limiting factors for a population.

A limiting factor is sometimes that restricts the size of a population. Limiting factors might affect the number of individuals in the ecosystem can support.

The amount of space affects a population’s size.

Available water, food, sunlight and temperature are all limiting factors.

Space is also a limiting factor.

If there are too few resources, populations may migrate to new areas.

QUESTION 3. What describes the relationship between a food chain and a food web?

Answers

Answer: A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels. Trophic levels include different categories of organisms such as producers, consumers, and decomposers.

Explain the flow of energy in the food chain and why stored energy is an important concept of it.

Answers

Answer:

"The process of transfer of energy to various trophic level of food chain is known as flow of energy. Energy flow in ecosystem from energy source to autotrophs to heterotrophs."

Explanation:

The energy flow from the primary members, plants  to the other level of organism in food chain. Storage of energy is very important because, the stored energy in plants are distributing to all other levels in food chain and utilizing for activities.

What is energy distribution in food chain ?

The sun is the main source of energy for practically all ecosystems on earth. Energy moves from one trophic level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose.

Primary producers are then consumed by primary consumers, who are in turn eaten by secondary consumers, and so on. The sun is the main source of energy for practically all ecosystems on earth.

Energy moves from one trophic level, or level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose. Only 10% of energy is distributed to the other level and 90% are lost to the surroundings.
