One possible model that could be used to show the transfer of energy within the lake ecosystem is a food web. A food web is a model that shows the flow of energy from one organism to another in an ecosystem.

In this food web, cyanobacteria would be at the bottom of the food chain, as they are producers that make their own food through photosynthesis. The mayfly larvae would be next in the food chain, as they eat the cyanobacteria. The small fish, such as yellow perch, would be at the next level of the food chain, as they eat the mayfly larvae. Finally, the larger fish, such as walleye, would be at the top of the food chain, as they eat the small fish.

The food web would be represented by a series of interconnected arrows, with each arrow pointing from the organism being eaten to the organism doing the eating. For example, an arrow would point from the cyanobacteria to the mayfly larvae, indicating that the larvae eat the cyanobacteria. Another arrow would point from the mayfly larvae to the small fish, indicating that the fish eat the larvae. And so on, until the top of the food chain is reached.

Overall, this model would show how energy is transferred from one organism to another in the lake ecosystem, with each organism occupying a specific position in the food chain.

Answer:

the transfer of energy in a lake ecosystem is a food web. In this model, the cyanobacteria are at the bottom and they are eaten by mayfly larvae. which is the larvae and then eaten by small fish like yellow perch, which are in turn eaten by larger fish such as walleye. The food web would be represented by arrows, showing the flow of energy from one organism to another. Each organism has a specific position in the food chain, with producers at the bottom and top predators at the top. This model demonstrates how energy is transferred through different levels .

Explanation:

Cyanobacteria, formerly known as blue-green algae, are photosynthetic microscopic organisms that are technically bacteria. They were originally called blue-green algae because dense growths often turn the water green, blue-green or brownish-green.

Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.

Answer : B

Explanation:

The liver is not a part of the immune system. The liver is an organ that plays a crucial role in detoxifying the body, producing bile to help digest fats and storing nutrients. While the liver indirectly supports the immune system by removing toxins from the bloodstream, it is not a part of the immune system itself.

Answer:

B. liver

Explanation:

The immune system is a complex network of organs, tissues, cells, and molecules that work together to defend the body against harmful pathogens, such as bacteria, viruses, fungi, and parasites.

A Mucous membranes: Mucous membranes are part of the immune system as they serve as a physical barrier that helps to trap and prevent pathogens from entering the body. They are found in various areas of the body, including the respiratory tract, gastrointestinal tract, and urogenital tract, and are lined with special cells that produce mucus and immune cells that help fight against pathogens.

B Liver: The liver is not directly part of the immune system. It is primarily responsible for detoxification, metabolism of nutrients, and production of important proteins, such as clotting factors. However, the liver does play a role in the immune response by filtering blood and removing pathogens, toxins, and other harmful substances from circulation.

C Skin: The skin is the body's largest organ and serves as a physical barrier against pathogens, preventing them from entering the body. Additionally, the skin contains specialized immune cells that help defend against pathogens that may breach the skin's barrier, making it an important part of the immune system.

D Saliva: Saliva, which is produced by salivary glands in the mouth, contains enzymes that can help break down food and also has antimicrobial properties that can help inhibit the growth of bacteria and other pathogens in the mouth. While saliva has some immune properties, it is not considered a primary component of the immune system.

It is considered fact because plants and animals are bother considered to belong to the Eukarya domain

Answer: Hey!

Myth: Mammals and plants don't belong in the same domain.

Fact: Mammals and plants do belong in the same domain.

Evidence: Domains classify by its amount of cells and the complexity of its cells.

Let me know if I answered your question incorrectly! <3

PART 1

1. the producer shown in the model is the grass. A producer is a consumers food.
2.the primary consumers shown in the model are the rabbits , the secondary consumers are the snakes. Consumators are the ones that ead the producer/s.


thats all i can help with ( im so sorry ) but i hope u manage to get help for the rest!

For 3. Two living parts could be the grass and one of the other animals, while two non living parts would be Oxygen and the sun. Oxygen interacts with the animals and provides life, while the sun provides growth to the grass, and the grass provides food for the consumers. And a consumer like the snake, provides the continuous chain and food for the next consumer

4. The ultimate of energy is the Sun. It provides energy to the grass, which then starts the food chain. Without the sun food chain simply wouldn’t work, and it would die off quickly.
