10. Why do different trophic levels have different amounts of energy?
Answers
Answer:
A food web can be formed by more than one food chain, since the webs includes all possible interactions that can occur between individuals of different trophic levels.
Explanation:
Based on the scheme shown in the image
1. How many food chains make up the food web?This food network is made up of three food chains
Plant → Bird → SnakePlant → Insect → Bird → SnakePlant → insect → Frog → SnakeFood webs often include several food chains, since they are due to the interaction between organisms at different trophic levels, which actually happens within an ecosystem.
2. Which organism is an herbivore?In this case, both the insect and the bird are herbivorous organisms, since they feed of the producer, which is the plant.
3. Which organism is an autotroph?The only autotrophic organism is the plant, since it is capable of manufacturing its nutrients from sunlight and inorganic matter.
4. Which organism is a third-order heterotroph? To what trophic level does that organism belong?The third order heterotroph is the snake, since it feeds on other animals. The snake is a carnivore and can be a secondary or more commonly tertiary consumer, so it can be placed in the 3rd or 4th trophic level.
5. Which organism is an omnivore?According to the scheme proposed, the bird is omnivorous, since it feeds on both plants and insects.
6. Which organisms belong to more than one food chain?In this case, the plant, the insect, the bird and the snake are part of more than one food chain.
Plant → Bird → SnakePlant → Insect → Bird → SnakePlant → insect → Frog → Snake 7. Which organism belongs to more than one trophic level?The bird can be located in both the second and third trophic level, being a primary consumer —when it feeds on plants— or secondary, when it feeds on insects.
8. What are decomposers? From which trophic levels are the organisms that decomposers feed on?Decomposers are generally bacteria and fungi, organisms capable of degrading organic matter, thus enriching the soil. Decomposers can feed on any trophic level.
9. What does a pyramid of energy show about the amount of energy available at different trophic levels of a food chain?As the ascent of the pyramid occurs —or at the upper trophic level— the amount of energy available decreases. This is because from one trophic level to another only 10% of the energy can be used. If a plant has 5000 Kcal available, the herbivore that consumes it can only use 500 Kcal.
10. Why do different trophic levels have different amounts of energy?The main reason for the difference in energy in each trophic level is that energy is lost in each one of them, which the organisms use in their metabolism. A consequence of the metabolism is the loss of energy as heat, which is acquired by the environment.

Which statement best compares a multicellular organism to a single-celled organism?
Answers
Answer:
A multicellular organism has organ systems that interact to carry out life functions, while a single-celled organism carries out life functions without using organ systems.Explanation:
Jaime and Ryan first noticed that something was wrong with their newborn baby about four months after birth. Their baby seemed to be having difficulty holding her head up. After a series of tests, it was noticed that fatty acids were not being digested by the cells and were accumulating on the child's nerve cells. Which organelle is not properly functioning in the cells of Jaime and Ryan's newborn baby?
Answers
Answer:
Liver
Explanation:
The liver is an organelle in the human body that is responsible for the digestion of fat. Liver produces bile, a digestive juice that helps in the digestion of fats and vitamins. Bile juice is stored in the gall bladder and move into the small intestine for the digestion of fat.
As per the details in the question, a newborn baby is unable to digest fat which is affecting the child's nerve cells. It means the newborn baby's liver is not functioning properly and not making bile juice that can digest the fat properly.
Hence, the correct answer is "Liver".

A wet mount of unstained Elodea ( a green aquatic plant) is observed using high power (400x) of a compound light microscope. Which structures would most likely be observed? ribosome, Golgi complex, and vacuole ribosome, Golgi complex, and vacuole nucleus, chloroplast, and cell wall nucleus, chloroplast, and cell wall centrosome, lysosome, and plasma membrane centrosome, lysosome, and plasma membrane cytoplasm, endoplasmic reticulum, and nucleolus
Answers
Answer:
The correct option is "nucleus, chloroplast, and cell wall"
Explanation:
The specimen described in the question is said to be green aquatic plant. Hence, the organelles expected to be viewed are those present in a pant cell.
Although, nucleus (stores the genetic material) is present in both plant and animal cells, however, chloroplast (to provide the green colour for the aquatic plant) and cell wall (for the cell's rigidity and support) are only found in a plant cells.

what happens to a enzyme after it has completed a reaction?
Answers
Answer: The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it releases its products (substrates).
Enzymes are not consumed in the reaction, they can continue catalyzing more reactions, they can remain bound to the product or they can be degraded.
What are enzymes?Enzymes are biomolecules that catalyze chemical reactions in living organisms. They are typically proteins, although RNA molecules known as ribozymes also exist. Enzymes are responsible for many of the metabolic processes that occur in cells and are essential for life. They are highly specific, meaning that they typically only catalyze one or a few specific reactions, and they increase the rate of reactions by reducing the activation energy required for the reaction to occur.
After an enzyme has completed a reaction, it is still present and can continue to catalyze more reactions. Enzymes can catalyze thousands of reactions per second, and they can remain active for long periods of time. However, enzymes can also be inactivated or destroyed by various factors, such as high temperatures, changes in pH, or the presence of certain chemicals

Answer:
5. c. active transport of molecules across a membrane
6. b. osmosis
7. d. water entered the cells of the lettuce by osmosis
Explanation:
5. The diffusion of water does not involve the budding of the cell membrane. The production of proteins amino acids and asexual reproduction are unrelated to the movement of molecules across the cell membrane. Therefore, this is active transport of molecules across a membrane.
6. The diffusion of water from a high concentration to a low concentration of water across a selectively permeable membrane is called osmosis. Transpiration is the process by which water leaves plant cells. Active transport requires energy. Capillary action is when water moves as a result of adhesion/cohesion.
7. When water enters the cells by osmosis, the cells become more turgid, making the lettuce crisp.
