Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem. All of the following must be addressed in your response to receive full credit:
a. Discuss the transfer of biomass when one organism eats another. Use your knowledge of digestion to discuss how food is broken down and used by the consumer.
b. Explain what happens to the energy that is not transferred from one organism to another.
c. Explain why there are typically fewer organisms at the top of an energy pyramid.
d. Use specific numbers and calculations to support your explanation.
Answers
The food chain and food web are used to transfer energy. Plants, who are the primary energy providers in the ecosystem, use their chloroplasts to collect sunlight, which is then partially converted into chemical energy during photosynthesis.
a)
When herbivores eat (are the primary consumers of) plants as food, this energy is transferred to the primary consumers in the food chain. This energy is stored in various organic products in plants. Then, the chemical energy contained in plant products is converted into kinetic energy, degrading the energy by turning it into heat. The secondary consumers come next. Further deterioration will occur when these herbivores are consumed by secondary consumers. Finally, energy will once more be destroyed when tertiary consumers eat the carnivores. As a result, the energy flow is only in one direction i.e., unidirectional.b)
Additionally, the energy flow in a food chain adheres to the 10% law.This law states that only 10% of energy is transferred from one trophic level to the next, with the remaining 90% being lost during the digestion process of the organism itself.c)
There are typically fewer organisms at the top of an energy pyramid because It has the least quantity of energy, the top level of an energy pyramid has the fewest organisms. Most ecosystems only have four trophic levels because there is eventually insufficient energy to maintain further trophic levels.d)
For instance, let us assume that a plant at the producer level produces 1000 Kcal of energy.When a primary producer eats this plant, it will only get 10% of the energy produced by the plant i.e., 1000/10 = 100 Kcal. the rest 90% will be used up by the plant itself for its metabolism.Further when a secondary consumer eats the primary consumer, it will only get 10% of the energy produced by the plant i.e., 100/10 = 10 Kcal.Lastly, as the tertiary consumer eats the secondary consumer, it will only get 10/10 = 1kcal.learn more about ecosystem here: https://brainly.com/question/842527

Answers
Answer: A
Explanation:
Lobes were the beginning of arms and legs, the correct option is A.
What are lobe-finned fish?Lobe-finned fish, unlike other fish, have a core protuberance in their fins that contains many bones and muscles.
The fins are extremely flexible and may be useful for supporting the body on land, as seen in lungfish and tetrapods.
The majority of bony fish have ray fins. These thin fins are made up of skin webs that cover flexible spines. Lobe-finned fish, on the other hand, have fins that look like stumps.
The lobe-finned fishes are the ray-finned fishes' sister group. They are distinguished by paired, fleshy pectoral and pelvic fins espoused by a single bone.
Prehistoric records clearly show that terrestrial vertebrates evolved nearly 400 million years ago from lobe-finned fishes.
Thus, the correct option is A.

During isovolumetric phases of the cardiac cycle, a. The atria are contracting and all heart valves are closed. b. All heart valves are closed. c. The ventricles can only be relaxing. d. The atria are contracting. e. Blood is being ejected into the aorta.
Answers
During isovolumetric phases of the cardiac cycle, the atria are contracting.
What happen in isovolumetric phases of the cardiac cycle?The isovolumetric contraction occurs in isovolumetric phase that causes left ventricular pressure to rise above atrial pressure. This leads to opening of aortic valve at the end of isovolumetric contraction when left ventricular pressure exceeds aortic pressure.
So we can conclude that during isovolumetric phases of the cardiac cycle, the atria are contracting.

What a part of a chemical equation are you able to by no means alternate?When you stability an equation you could most effectively alternate the coefficients (the numbers in the front of molecules or atoms). Coefficients are the numbers in the front of the molecule. Subscripts are the smaller numbers observed after atoms. These can not be modified while balancing chemical equations.
The complete question is Which part of the chemical equation is incorrect which is 2C4H10+ 10O2 - 8CO2+10H2O.
To realize if a response is properly balanced among the reactants and the products, you need to calculate the wide variety of atoms of every detail on each aspect of the response and to test if they may be equal.For oxygen, there are 20 oxygen atoms withinside the reagents and 26 withinside the products, so it's miles essential to grow the wide variety of oxygen withinside the reactants (with out touching the others). For this we positioned thirteen 02 withinside the reactants rather than 10, to have 26 oxygen atoms on every side.Read more about the equation :

1. Erythropoietin will be higher at low altitude. Erythropoietin or EPO level will be higher because of the raised blood oxygen training but its lasting period will depend on the training content as here it is only 2 months.
About high erythropoietin:
Among the objectives of altitude training is to improve athletes' sea-level endurance performance by raising blood oxygen carrying capacity. The attainment of improved haematological variables is mostly due to the augmented erythropoietin (EPO) production in hypoxia. The duration of exposure and degree of hypoxia affect the level of the erythropoietin EPO rise and the rate of erythropoiesis acceleration. The haematological response to altitude training may also be influenced by a wide range of additional factors.
2. 100 ml of blood contain 27.8 mL of oxygen. This can be said as it has been shown that a healthy person typically possesses 20 grammes of haemoglobin in every 100 millilitres of blood.
Procedure:
=20∗1.39
=27.8mL
Amount of oxygen found in 11 grams of hemoglobin is equal to 1.39 milliliters of oxygen.
Thus, the total amount of oxygen in milliliters would be equal to product of total weight of hemoglobin and the total amount of oxygen in ml in one gram of hemoglobin.
3. Athletes training at high altitude have more oxygen molecules. They have an advantage as a result of having more red blood
Why so:
Higher elevations have thinner air, which has less oxygen molecules per volume of air. The body therefore makes more red blood cells when athletes workout at these high elevations. For up to 20 days, these additional blood cells remain in the body. Also as a result of having more red blood cells, their blood can carry more oxygen. When they compete at lower elevations, their muscles naturally get a boost from more oxygen.

How the herbivores have longer digestive systems compared to carnivores?We can conclude that the herbivores have longer digestive systems compared to carnivores.
Carnivores feeds on other animals whereas herbivores eats plants.Most herbivores have a four stomach compartment system that helps them process and digest their food.This is because they have to process cellulose in plants which needs to be properly broken down.Flesh-eating carnivores do not require this arrangement.The four stomach compartment of most herbivores includes Rumen, Reticulum, omasum and abomasum.They also chew the cud whereby they regurgitate food materials.Thus, this could be the answer.

For fruits/vegetables, why do some sugars exist in simple forms and some sugars in complex forms?
Answers
Simple sugars are a type of carbohydrate. Carbohydrates are one of the three basic macronutrients — the other two being protein and fat.
Simple sugars are found naturally in fruits and milk, or they can be produced commercially and added to foods to sweeten, prevent spoilage, or improve structure and texture.
Monosaccharides are the simplest carbs, in that your body cannot break them down further.
This allows your body to absorb them quickly and easily, with the exception of fructose.
There are three types of monosaccharides (1Trusted Source):
Glucose: Fruits and vegetables are natural sources of glucose. It’s also commonly found in syrups, candy, honey, sports drinks, and desserts.
Fructose: The primary natural dietary source of fructose is fruit, which is why fructose is commonly referred to as fruit sugar.
Galactose: The main dietary source of galactose is lactose, the sugar in milk and milk products, such as cheese, butter, and yogurt.
