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.

Answer: The wind erodes the earth by moving pieces of it every which way.
Explanation:
Every patch of air carries hundreds of thousands pieces of dirt sand and chunks of earth. When the wind changes course it will slowly pick up more and more and until an indent will form. This is also how sand dunes are made.
Answer:
If the wind constantly pushes a rock, eventually the sides will start eroding, and the wind will cause it to break and erode.
The blowing wind constantly changes the earths surface by moving rocks, and breaking them.
by the wind constantly pushing sand on top of each other in one place.

HELP IMPORTANT TEST!! Why must animals eat food but plants do not eat food? A: Plants do not appear to eat, but they do actually eat nutrients in the soil. Animals must eat to obtain food that they can't get from the soil. B:Plants make their own food through photosynthesis. Animals must eat because they cannot make their own food. C: Plants use photosynthesis to make their own food instead of eating. Animals eat plants because they like the taste of certain fruits. B: Plants make their own food through photosynthesis, so they do not eat. Animals eat because the energy they make themselves is enough to live but not grow. By eating, they can grow big and strong.
Answer:B
Explanation:The answer is B because plants use photosynthesis to make their own food while animals such as humans do not make their own food using the sun photosynthesis is using the suns Energy to produce your own food If you think about it humans are animals and do you use the suns energy to produce your own food no

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

Answer:
- The amount of space affects a population's size.
- Available water, food, sunlight and temperature are limiting factors
- Space is also a limiting factor.
- If there are too few resources, populations may migrate to new areas.
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 something that restricts the size of a population. Limiting factors might affect the number of individuals in the ecosystem can support.
Resources affect
populations
Living and nonliving things are both found within the same ecosystem. the living things require the non living things for survival.

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.
