Explanation:
Arrows have come to represent protection and defence from any evil that can come to you. Sustenance – Arrows were used to fight enemies and to hunt food, two important aspects of sustaining life. As a result, an arrow symbolizes maintaining and protecting life.
REAL NAME - SHRESTH DUBEY
The arrows in a food chain represent the flow of energy or the transfer of nutrients between different organisms in an ecosystem.
They indicate the direction of energy transfer, showing which organism is being consumed by another. The arrow always points from the organism being consumed (prey) to the organism consuming it (predator).
The primary producers, such as plants or algae, are at the beginning of the food chain and transfer energy to herbivores (primary consumers), which are then consumed by carnivores (secondary consumers) or other higher-level consumers.
The arrows help depict the interconnectedness and energy flow within an ecosystem, illustrating the feeding relationships between organisms.

Cells can best be described as
Cells can best be described as the fundamental units of life. They are the building blocks of all living organisms, including plants, animals, and even microorganisms.
Here are some key characteristics that describe cells:
1. Structure: Cells have a defined structure with a plasma membrane that separates the internal components of the cell from the external environment. Inside the cell, there is a variety of organelles, such as the nucleus, mitochondria, and ribosomes, each playing a specific role in cell function.
2. Function: Cells carry out various functions necessary for life. They perform metabolic processes, such as respiration, photosynthesis, and protein synthesis. Cells also maintain homeostasis, which involves regulating internal conditions to keep the cell functioning optimally.
3. Reproduction: Cells have the ability to reproduce. They can divide and create new cells through processes like mitosis and meiosis. This ensures the growth, development, and repair of tissues and organs.
4. Genetic Material: Cells contain genetic material in the form of DNA (deoxyribonucleic acid). DNA carries the instructions for cellular activities and determines the characteristics of an organism. It is organized into genes, which are passed on from one generation to the next.
5. Specialization: Cells can be specialized to perform specific functions within an organism. For example, muscle cells contract to enable movement, while nerve cells transmit electrical signals for communication. This specialization allows multicellular organisms to have different cell types that work together to maintain overall function.
Overall, cells are the basic structural and functional units of life. They are responsible for all the processes necessary for an organism's survival and are crucial for maintaining life's complexity and diversity.

Hundreds of years ago, a volcanic eruption killed many plants and animals on a tropical island. Today, the island looks much as it did before the eruption. Why is this true? Destroyed ecosystems always return to their exact original state. Altered ecosystems only regain stability from the development of grasses. Geographic barriers prevent the migration of animals to island habitats. Destroyed environments can recover through ecological succession.
Answer:
Destroyed environments can recover through ecological succession.
Explanation:
Ecological succession describes a progressive change in the species in an ecological community over time.
This can happen after some disturbance such as a fire, earthquake, or volcanic eruption. It can mean that a e can return to the state it was before the event.

Off the coast of the Pacific Northwest in the United States, the Pacific plate is being pushed underneath the North American plate in a subduction zone, caused by plate tectonics. As the rock from the Pacific plate is pushed under the North American plate, it is subjected to high temperatures and pressures. Which rock will be created from this process?
Answer:
Metamorphic rocks
Explanation:
When two oceanic plates collide, it occurs oceanic convergence. The thicker and older plate subduces under the other plate. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. The fast subduction originates magma. In the western Pacific crust is old and thick, and hence it submerges easier in the mantle.
Metamorphism provokes structural and mineralogic reordering in an original preexisting rock, under the influence of factors such as temperature and pressure, which are two of the most important and influencing ones.
This physic-chemical processes usually occur in deepness, many times related to plates movement and subduction processes. The sharped temperature rising might be caused by magma injection or by a deep placement or the original rock in a subduction zone.
According to the metamorphism processes, there are different kinds of metamorphic rocks. Metamorphic rocks that are the product of subduction event, belong to "regional metamorphism" which includes a huge area, and among this classification, "underground metamorphism" is associated with plates subduction, with a range temperature among 400-600ºC.

13. In a forest, why do you rarely see young pine trees growing under a broad-leaved tree, such as a maple? If broad-leaved trees eventually take over a forest as pines die off, how does that affect other organisms living in the forest? How does it affect this forest ecosystem?*
Answer:/Explanation:
Broad leaved trees would block the sunlight due to the size of their leaves. This would reduce the amount of sunlight that the pine tree could absorb, and would therefore inhibit its ability to efficiently perform photosynthesis. This would reduce the amount of food it could synthesise, and interfere with its growth and reproduction.
Without pine trees, the diversity of the ecosystem would be reduced. Several organisms rely on pine seeds and leaves as a food source. In the absence of pine trees, competition for other food sources could increase, and certain birds, squirrels etc. could die off.
Pine trees are also a habitat for many birds and small creatures. Without these trees, these animals could struggle to find efficient shelter.

Which of these chemicals is not a pollutant?
A. Methane
B. Nitrogen gas
C. Nitrate
D. Carbon dioxide
Answer:
All these chemicals are primary causes of pollution. Although, only one isn't an air pollutant. Which would make my best Guess C. Nitrate
Explanation:
A. Methane Is the main component in gas and oil. Oil companies have been responsible for polluting our air with about seven million tons of methane per year.
B. Nitrogen gas in general is one of the main air pollutions. otherwise know as Nitrogen dioxide.
C. Nitrates are found in ground waters and transfers into the soils surrounding said waters. Nitrates commonly are a cause of death in infants when drinking tab water or eating crops grown from nitrate infected soils. Adults aren't nearly as infected by this.
D. Carbon Dioxide is a greenhouse gas that pollutes our air and has been a main cause of global warming.
I'm at a loss for answering this question since all of these are polluting our earth in some way. The only way I can think to answer this is that all but one are air pollutants. So maybe the one that is not a air pollutant is the correct answer. My best guess is C. Nitrate
