1. How many food chains make up the food web?
2. Which organism is an herbivore?
3. Which organism is an autotroph?
4. Which organism is a third-order heterotroph? To what trophic level does that organism belong?
5. Which organism is an omnivore?
6. Which organisms belong to more than one food chain?
7. Which organism belongs to more than one trophic level?
8. What are decomposers? From which trophic levels are the organisms that decomposers feed on?
9. What does a pyramid of energy show about the amount of energy available at different trophic levels of a food chain?
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.

What characterizes a hypotonic solution?
a. More solute & solvent than another solution
b. Less solute & solvent than another solution
c. More solute than another solution, but less solvent
d. Less solute than another solution, but more solvent
Answers
Hi :)
A hypotonic solution has a lower concentration of solutes than another solution
In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol
Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated

Aquatic organisms are able to survive when the temperature decreases. These organisms survive even when the surfaces of lakes and ponds are covered with ice. Which property of water best explains how aquatic organisms can survive during freezing temperatures?
Answers
Answer:
Anomalous expansion
Explanation:
Anomalous expansion of water is the abnormal way water expands when exposed to low temperature.
At 4 degree Celsius , the density at the top layer is usually at the Maximum which makes the water sinks down and then the water in the lower layer rises up.
When the temperature drops below 4 degree Celsius, the water molecules at the top then freezes leaving the denser molecules at the bottom which doesn’t freeze as a result of their high density.
This way, organisms can survive in the water due to the lower layer not freezing.

compare and contrast coal and nuclear power. would you support either of both of these forms of energy technology. why or why not?
Answers
Answer:
I will give you a basic idea of what you should write in my opinion you should support neither of these forms of energy mainly due to the reason that both forms of energy pollute the world. instead we should focus on using renewable energy such as solar wind and hydro. furthermore coal and nuclear power are non-renewable resources which means that there is only a limited amount on the earth which brings up the benefit of having renewable energy as there is endless supply of it.
