Trophic webs are nets constructed by different interacting organisms that involves energy transference. A) The model tracks the transfer of energy as energy flows in the ecosystem.
What is a trophic web or a food web?
The trophic web -also known as food web- is the interaction between different organisms involving transference of energy when some of them feed on the other ones. The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
The first link corresponds to a producer organism -autotroph-.The following links are the consumers -heterotrophs-: herbivores and carnivores.The last links are the decomposers that degrade organic matter from dead organisms.Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.
Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
Option A is correct. The model tracks the transfer of energy as energy flows in the ecosystem.

James is investigating the germination of bean seeds. He plants 30 bean seeds each in three identical 30-centimeter-by-30-centimeter square containers and plans to give the same amount of sunlight and water to each container. He will place each container in a different room, with each room at a different temperature. Which of these hypotheses is the most appropriate for this research project? If the size of the container increases, then the number of seeds that germinate will increase. If the temperature of the room decreases, then the number of seeds that germinate will decrease. If the amount of water given to the seeds increases, then the number of seeds that germinate will increase. If the number of seeds planted in the container increases, then the number of seeds that germinate will decrease.
Answer:

Explanation:
Analyzing core samples from around the Mid-Atlantic ridge, the seafloor further away from the ridge was much _________________ than that near the ridge. This led to a new theory called Sea Floor Spreading.
Analyzing core samples from around the Mid-Atlantic Ridge, the seafloor further away from the ridge was much older than that near the ridge.
Why is the seafloor further away?This led to a new theory called Sea Floor Spreading, which suggests that new oceanic crust is continually formed at the Mid-Atlantic Ridge and then moves away from the ridge, eventually being consumed at deep-sea trenches.
As the new crust moves away from the ridge, it cools and becomes progressively older. This process of sea floor spreading helps explain many geological features of the ocean basins, including the presence of mid-ocean ridges, deep-sea trenches, and oceanic islands.

Myth: Tigers and goldfish are not related.
Fact:
Evidence:
Myth: An organism's kingdom only describes physical characteristics.
Fact:
Evidence:
Myth: Mammals and plants don't belong in the same domain.
Fact:
Evidence:
Answer:
Myth: Tigers and goldfish are not related.
Fact: Tigers and goldfish are not closely related according to their genetic and biological classification.
Evidence: Tigers belong to the Panthera genus in the family Felidae, which means they are a type of big cat. Goldfish, on the other hand, belong to the Carassius genus in the family Cyprinidae, which is a type of small freshwater fish. While both are animals, their biology and genetic make-ups are different and they are not closely related to each other.
Myth: An organism's kingdom only describes physical characteristics.
Fact: An organism's kingdom classification is based on their cell type, method of obtaining energy, and other biological characteristics, not solely their physical features.
Evidence: The five kingdoms of life, namely Monera, Protista, Fungi, Plantae, and Animalia, are characterized by their distinct cellular structures, methods of obtaining energy, and other features. For example, animals are multicellular, heterotrophic organisms that rely on consuming other organisms for energy, while plants are autotrophic, photosynthetic organisms that use sunlight and carbon dioxide to produce energy. These biological factors determine an organism's kingdom classification.
Myth: Mammals and plants don't belong in the same domain.
Fact: Mammals and plants belong to different domains of life, but they both belong to the larger group known as eukaryotes, meaning they have cells with a nucleus.
Evidence: The three domains of life are Archaea, Bacteria, and Eukarya. Mammals, along with other animals, fungi, and protists, belong to the Eukarya domain, while plants belong to the Plantae kingdom within the same domain. Despite their differences, both groups share similar cell structures and other characteristics that distinguish them from the other two domains, Archaea and Bacteria.
Myth: Tigers and goldfish are not related.
Fact: Tigers and goldfish are not closely related in terms of their species. Tigers belong to the Felidae family and are classified as mammals, while goldfish belong to the Cyprinidae family and are classified as fish. However, both tigers and goldfish belong to the broader category of animals, as they are both living organisms.
Evidence: The classification system in biology groups organisms based on their similarities and differences. Tigers and goldfish belong to different families within the animal kingdom, indicating that they are not closely related.

Myth: An organism's kingdom only describes physical characteristics.
Fact: An organism's kingdom classification does consider physical characteristics, but it also takes into account other factors such as cell type, mode of nutrition, and reproductive strategies. Physical characteristics alone are not sufficient to determine an organism's kingdom.
Evidence: The five main kingdoms in the classification system are Monera (prokaryotes), Protista (eukaryotes that are not plants, animals, or fungi), Fungi (eukaryotic decomposers), Plantae (eukaryotic photosynthetic organisms), and Animalia (eukaryotic multicellular organisms). These kingdoms are based on a combination of physical characteristics, cellular organization, and other traits.

Myth: Mammals and plants don't belong in the same domain.
Fact: Mammals and plants do not belong in the same domain. Mammals belong to the domain Eukarya, while plants belong to the same domain. Both domains have distinct characteristics and are separate classifications in the biological classification system.
Evidence: The three main domains in the classification system are Bacteria, Archaea, and Eukarya. Mammals, including humans, belong to the domain Eukarya, which also includes other organisms with complex cellular structures. Plants, on the other hand, are also classified under the domain Eukarya. Both mammals and plants have eukaryotic cells, but they have different characteristics and evolutionary histories.

Explanation:
Pointed teeth help tear apart food, and large, flat teeth are used to grind food. Based on this information, what types of teeth are characteristic of animals that eat plants and animals that eat other animals?
Answer:
Flat teeth are characteristic of animals that eat grass, because they grind food in the form of grass in the oral cavity. And predators need sharp teeth in order to tear off flesh, they often do it poorly chewed, and swallowed whole as soon as the flesh was torn off. This is because herbivores can move their jaws to the left and right, while carnivores cannot.
Answer:
Explanation:-
The type of teeth in animals that eat plants are flat teeth used to grind food. The type of teeth in animals that eat other animals are pointed teeth that help tear apart food.
Herbivores are the animals that fall into the category of plant eating animals. They usually feed on plants which require grinding. They ,hence, have large and flat premolars which are highly functional in chewing the plants. These teeth also help in digestion of herbivores. Since, there is no tearing flesh ,the canines are not of much use. On the other hand, carnivores are the animals that fall into the category that eat other animals. They feed on flesh which require tearing so they have sharp canines to rip the flesh.

The 10% rule states that only 10% of the energy stored as biomass at one level is available for the following level. Diatoms are the organisms with the most available energy.
What is the 10% rule?
The 10% rule refers to the energy flow along the trophic chains from autotrophs to heterotrophs and detritivorous organisms.
From the solar energy input, it occurs a unidirectional energy flow through all the organisms in the ecosystem.
Only 1% of the solar energy that reaches the Earth's surface is absorbed by autotroph organisms.
From there, each trophic level transmits 10% of its energy to the following trophic level. The remaining 90% is lost to the environment as heat.
According to these amounts, The 10% rule states that only about 10% of the energy stored as biomass at one trophic level per unit of time ends up as biomass at the next trophic level, in the same unit of time.
In the exposed trophic web, and following the 10% rule, diatoms are the organisms with the most available energy considering their biomass. Only 10% of its energy will be transferred to the second level, 1% to the third level, 0.1% to the fourth level, and 0.01% to the fifth level.

Look at the diagram below. In what direction will the oxygen move?
1, 2, or 3
Answer: Blood to tissue fluid.
Explanation:
The respiring tissue needs oxygen (as it is carrying out aerobic respiration). Because of this, it oxygen needs to reach this tissue someway, somehow. And this is via the blood.
The blood contains cells called red blood cells. These cells are responsible for delivering oxygen to the rest of the body. When the oxygen inside these cells reaches the part of the body where oxygen is needed, the oxygen will diffuse through the walls of the artery (out of the blood vessel, into the respiring tissue).
