Fungus is an organism not drawn in the above food chain although it has a very important role. Describe an important role of organisms such as fungi and bacteria can you help me plz!!!
Answer:
Explanation:
Fungi and bacteria are decomposers. This means they help breakdown dead plant and animal matter.
This is kind of a baseline descripiton but i hope it helps!
Two of the most crucial creatures in an ecosystem are fungi and bacteria. They are essential for the nutrition cycle, the breakdown of organic matter, and the generation of food for other species. In order for other creatures to exploit the complex organic compounds, fungi and bacteria convert them into simpler forms.
What is the way to the food chain ?For instance, when dead plants and animals are broken down by fungi and bacteria, vital nutrients like nitrogen, phosphorous, and sulphur are released into the soil. Following the uptake of these nutrients by plants, food is produced that is then devoured by other species in the food chain.
Additionally, bacteria and fungi collaborate with other living things like plants in symbiotic interactions. For instance, several fungi collaborate with plant roots to provide the providing the plant with nutrients it needs in exchange for carbs.
Mycorrhizal symbiosis is the name for this kind of partnership, which is necessary for the development and well-being of plants. Since many bacteria and fungi produce chemicals that can stop the formation of dangerous infections, they also play a significant part in disease prevention.
Finally, fungus and bacteria are significant food sources for many organisms. For example, fungi like mushrooms and others feed animals like deer, birds, and other fauna.

How do scientists find the epicenter of an earthquake?
Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects.
How do i know if its entering or leaving or neither just by the precentage?
Answer:
1. Shrink
2. Swell
3. Neither
Explanation:
The percentage of water indicates how pure the water is, i.e. how concentrated the molecules of water are.
The higher the percentage of water, the more water molecules there are in the space.
Water molecules move from a high concentration to a low concentration across a semi permeable membrane, by the process of osmosis.
In beaker 1, the water outside is 89%, and inside the bag is 92%. That means the water inside the bag is at a higher concentration than outside. That means water will leave the bag, moving from a high concentration to a lower concentration outside. The bag will shrink.
In beaker 2, the water outside is 97%, and inside is 92£%. That means the water inside the bag is a lower concentration than outside. That means water will enter the bag, moving from a higher concentration outside to a lower concentration outside. The bag will swell.
In beaker 3, the concentration of water inside and outside is the same. That means they are in an equilibrium (the movement is balanced) so neither will occur

Muscles in the small intestine are _____.
smooth
striated
involuntary
voluntary
cardiac
Pls pick multiple
Answer:
smooth and involuntary
Two layers of smooth muscle form the small intestine. The outermost layer is the thin, longitudinal muscle that contracts, relaxes, shortens, and lengthens the gut allowing food to move in one direction. The innermost layer is a thicker, circular muscle.
Also smooth muscle is not under our control so is called involuntary
PLEASE HELP ME Are humans predators in their ecosystem? Explain in at least 5 sentences.
Their new study shows that humans are strange predators. Unlike other animals, we target adult prey in large numbers. That is a practice that can push populations of those prey into decline, the researchers warn. People mainly target — at least among wild mammals and fishes — prey that are old enough to reproduce.
Humans are considered to be apex predators in their ecosystems due to their ability to manipulate and dominate other species through hunting, agriculture and urbanization.
Why are human predators?Humans are considered to be apex predators in their ecosystem due to their ability to manipulate and change their environment to suit their needs. Humans have the ability to hunt and consume a wide variety of other organisms, including other predators. Humans also have a significant impact on the environment through activities such as deforestation, pollution, and hunting.
However, humans are also capable of acting as stewards of the environment and preserving biodiversity through conservation efforts. The relationship between humans and their ecosystem is complex and multifaceted.

It takes place when magma introduces
great amount of heat into an existing rock
resulting in the recrystallization and mineral
reaction in the rock.
Answer:
The correct answer is - contact metamorphism.
Explanation:
Contact metamorphism is one of the two metamorphism processes which takes place when the pre-existing rock is introduced to a great amount of heat which affects it by an intrusion of magma. It is known as a low pressurized, high-temperature type of metamorphism.
An example of this type of metamorphism which experiences recrystallization in the rock and forms a metamorphic marble that is formed by the recrystallization and mineral reaction of the limestone.

True or False: Enzymes have an optimal or ideal pH level?
Answer:
All enzymes have an ideal pH value, which is called optimal pH. Under the optimum pH conditions, each enzyme showed the maximum activity. For example, the optimum pH of an enzyme that works in the acidic environment of the human stomach is lower than that of an enzyme that works in a neutral environment of human blood. All enzymes have an optimum pH that they work best at. Its often neutral pH 7, but not always.
