Answer: You die if no digest
Explanation:
Food needs to be digested because your body can't contain large stuff whole, so it has to be converted into a smaller amount. For Instance, if you were to eat a entire turkey then your body would just explode I guess if you wouldn't digest it. Also, without digesting food you can't enter new food into your body. Therefore, this is why food needs to be digested.

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.

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.

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.
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:
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.

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.
