Decomposition is the process by which:
Carbon atoms are released into the soil
Carbon is converted to CO2
Organisms obtain energy by breaking down glucose
Answer:
carbon is converted into co2.
Explanation:
Energy can change in two different ways. It can undergo a transfer, or it can undergo a transformation. For each of these examples of how energy is changed, write the correct answer in the blank.
In photosynthesis, solar energy undergoes a _______ when it changes from light energy to chemical energy. When the sun warms Earth’s surface, thermal energy is ___________ to land and water.
Answer:
Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery.
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.
While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.
Explanation:
Matter is recycled within and between ecosystems through closed loops called biogeochemical cycles. How is this unlike how energy is passed through ecosystems?
Answer:
Energy flows in a one-way direction i.e. unidirectional flow
Explanation:
Matter and energy both pass through an ecosystem as organisms feed on one another. However, as rightly emphasized in this question, matter in form of elements such as water, nitrogen, phosphorus etc. moves in different directions and is recycled within and between ecosystems through closed loops called biogeochemical cycles.
Contrarily to how matter is recycled in an ecosystem i.e. within and between, ENERGY only flows in one direction. Energy enters an ecosystem in form of light (sun) and is passed down from one trophic level to another starting from the producers. This unidirectional pattern of energy flow differentiates energy flow from matter recycling.
Question 1 (5 points)
Geologic time periods are divided into segments based on two pieces of information.
Describe them.
Answer:
Geologic time spans are divided into units and subunits, the largest of which are eons. Eons are divided into eras, which are further divided into periods, epochs, and ages.

Explanation:
what are the possible blood types of a child whose parents are both heterozygous for b blood type
Answer:
I believe the answer is:
If both are BB, the child will be BB. If one is BB and one is BO, the child has a 50% chance of being BB and 50% chance of being BO - both of which result in type B. However, if both parents are BO, there is a 25% chance of BB, a 50% chance of BO, and a 25% chance of OO (which results in type O).

What could happen to the birds if the grasshoppers disappear? WHY?
Answer: The grasshoppers are the herbivorous insects. These insects feed on leaves and grasses. ... The population of predatory birds, snakes and other animals feed on grasshoppers. If the grasshoppers become suddenly extinct, then the population of higher organisms will also decline in number or even extinct.
Hope this helps....... Stay safe and have a Merry Christmas!!!!!!!!! :D
I also want to say something.... My account got deleted yesterday and i would like if you would add me.....
Answer:
The birds would either go hungry or have to find something else to eat.
Explanation:
Grasshoppers are on most birds' diet so if the grasshoppers suddenly dissapeared, a lot of birds would be without a food source. So, those birds would either go hungry with nothing to eat or a meal substitute.

Energy Flow through Ecosystems with Decomposers
The diagram below represents some energy transfers in an ecosystem.
Which type of organism is most likely represented by letter X?
decomposer
O autotroph
producer
O herbivore
1
2
3
4
5
6
7
8
Answer:
The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. ... At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. The herbivores at the second trophic level, use the plants as food which gives them energy.

Patrick met Patti at the dance. Both of them are heterozygous for their pink body color, which is dominated over a yellow body color.
Radish color is controlled by a gene that exhibits incomplete dominance; purebred red radishes (RR) crossed with purebred white radishes (WW) make purple radishes (RW). What are the chances of producing purple offspring when you cross two purple parents?
Answer:
1/2
Explanation:
This question involves a single Gene coding for fruit color in radish plants. The gene exhibits incomplete dominance where the allele for red radish (R) and the allele for white radish (W) forms a hybrid with a purple radish (RW).
If a purebred red radish (RR) is crossed with purebred white radishes (WW), purple radishes (RW) will be formed. However, when the purple radishes are self-crossed i.e. RW × RW, the following gametes will be produced- R and W.
Using these gametes in a punnet square (see attached image), the following offsprings will be produced in the following proportions:
RR - red = 1/4
RW - purple = 2/4 or 1/2
WW - white = 1/4
Hence, the chances of producing purple offspring when you cross two purple parents is 1/2.

In another population, the white spot allele frequency is 0.55. What percentage of the moth population has white spots?
Answer:
The correct answer is - 30.25%
Explanation:
Allele frequency in a population is the number of a particular allele in the population divided by the total number of all alleles present in the population for the particular gene.
The population has the allele frequency or q = 0 .55
So, the percentage of the white spots moth in this moth population would be -
q^2 = (0.55)^2
q^2 = 0.3025
q^2 = 0.0325 *100
= 30.25 %

Explain how gravity causes rocks to fall off a cliff. ❤️
Answer:
Gravity has a strong pull and when rocks aren't in a good position/stable position they start to fall.
Gravitational Erosion
Explanation:
When chunks of stone fall from a mountainside to the ground below, it is because gravity pulled it down. When a glacier moves through a mountain range, slowly flattening or carving the earths surface in that area, it is because the pull of gravity forces the glacier downhill.
How do humans study and measure caves at the Yucatan Peninsula?
Answer:
when i first read this i thought it said penis
Explanation:
GIVE ME ATTENTION
Answer:
They use different technological devices to measure caves at the Yucatan Peninsula.
Explanation:
Background Reading:
Human presence on the Yucatán Peninsula reaches back to the Late Pleistocene. Osteological evidence comes from submerged caves and sinkholes (cenotes) near Tulum in the Mexican state of Quintana Roo. Here we report on a new skeleton discovered by us in the Chan Hol underwater cave, dating to a minimum age of 9.9±0.1 ky BP based on 230Th/U-dating of flowstone overlying and encrusting human phalanges. This is the third Paleoindian human skeleton with mesocephalic cranial characteristics documented by us in the cave, of which a male individual named Chan Hol 2 described recently is one of the oldest human skeletons found on the American continent. The new discovery emphasizes the importance of the Chan Hol cave and other systems in the Tulum area for understanding the early peopling of the Americas. The new individual, here named Chan Hol 3, is a woman of about 30 years of age with three cranial traumas. There is also evidence for a possible trepanomal bacterial disease that caused severe alteration of the posterior parietal and occipital bones of the cranium. This is the first time that the presence of such disease is reported in a Paleoindian skeleton in the Americas. All ten early skeletons found so far in the submerged caves from the Yucatán Peninsula have mesocephalic cranial morphology, different to the dolicocephalic morphology for Paleoindians from Central Mexico with equivalent dates. This supports the presence of two morphologically different Paleoindian populations for Mexico, coexisting in different geographical areas during the Late Pleistocene-Early Holocene.
