What is the rock cycle?The rock cycle is a cycle of processes that describes how each of the three main rock types forms and disintegrates as a result of various applications of heat and pressure over time.
Crystallization, metamorphism, and erosion and sedimentation are the three processes that transform one rock into another.
Any rock can change into any other rock by going through one or more of these processes. The rock cycle is a result of this.

A.
Organisms at the top of the pyramid can only generate energy directly from the sun.
OB.
There is too much energy available at the top of the pyramid.
OC. There is much less energy available at the top of the pyramid.
pen by many other organisms
The correct answer is: There is much less energy available at the top of the pyramid. and i got some FYIS for you did you know that
An energy pyramid is a graphical representation of the flow of energy at each trophic level in an ecosystem. The width of each bar represents the units of energy available within each trophic level; the height is always the same. The flow of energy moves through the layers of the energy pyramid from the bottom-up, and is gradually reduced as energy is used up by the organisms at each level.
The base of the energy pyramid indicates the energy available within primary producers. Primary producers, also known as autotrophs, are organisms that make their own food by taking their energy from non-living sources of energy, such as the sun. In most cases, these are photosynthesizing plants, which use energy from the sun to create their own nutrition in the form of simple sugars.
All other levels in the energy pyramid consist of heterotrophs – organisms that obtain their nutrition from organic carbon, usually in the form of other plants and animals. The second trophic level consists of primary consumers. These are the herbivores that feed solely on primary producers. The third and fourth levels are made up of secondary consumers and tertiary consumers. These are carnivores and omnivores, which can feed on any of the lower levels, although mainly consume organisms from the trophic level directly beneath them. The top layer of the energy pyramid contains apex predators. These are mostly carnivorous animals that have no natural predators.
The pyramid shape is used to represent the flow of energy because of the way that energy is used up and lost throughout the system. The primary producers take in energy from the sun. However, only around 1% of the total available sun energy is actually absorbed into the plants; this is the GPP or the Gross Primary Productivity. Plants use photosynthesis to convert energy from the sun into chemical energy, which is stored as organic compounds such as sugars. The plants then carry out cell respiration to convert the sugars into usable energy molecules such as ATP (adenosine triphosphate). Cell respiration is a metabolic reaction that uses up around 60% of the plant’s energy, leaving around 40% of the GPP as the NPP, or Net Primary Productivity. This NPP value represents 100% of the total energy units made available for the plants to use.
The primary consumers then consume some of these plants and obtain some of their stored energy. However, not all plants are consumed by herbivores; some die or are decomposed by other organisms such as fungi and bacteria. Furthermore, not all parts of a plant are digestible by herbivores; some parts are indigestible and are excreted as waste. Moreover, herbivores also use up some of their obtained energy for their own cell respiration and other life processes such as growth, movement, and reproduction. As a result, only around 10% ofhe energy available at the plant level is transferred to the herbivore level. This is called the energy transfer efficiency, which is the ratio of energy available at one trophic level to the energy available at the next trophic level. The same process of energy loss occurs at each subsequent trophic level, as some organisms die or are not consumed, some parts are indigestible and are excreted as waste, and some energy is used up for cell respiration and other life processes. Therefore, the energy transfer efficiency is usually around 10% for each level of the energy pyramid.
This means that there is much less energy available at the top of the pyramid than at the bottom. For example, if the primary producers have 1000 units of energy, then the primary consumers will have only 100 units of energy, the secondary consumers will have only 10 units of energy, and the tertiary consumers will have only 1 unit of energy. This explains why there are very few organisms toward the top of the pyramid; there is not enough energy to support a large number of organisms at higher trophic levels. The higher the trophic level, the fewer the organisms and the larger the individual organisms tend to be.

What does lightning contribute to that can ultimately help local ecosystems recycle nutrients in the soil?
Noise pollution
Wildfires
Migratory navigation for birds
Heat in local bodies of water
Lightning can contribute to wildfires, which can ultimately help local ecosystems recycle nutrients in the soil. When lightning strikes a tree, it can start a fire that burns dead and decaying matter on the forest floor, releasing nutrients like nitrogen, phosphorus, and potassium back into the soil. These nutrients can then be absorbed by plants and used to fuel new growth. The ash left behind by the fire can also enrich the soil with essential minerals that are beneficial for plant growth.
While wildfires can be destructive and dangerous, they are also a natural part of many ecosystems and can help to maintain their health and diversity. In some cases, wildfires are even intentionally set by land managers to promote ecosystem health and reduce the risk of more dangerous fires in the future.
Therefore, while lightning itself does not directly contribute to nutrient recycling in the soil, it can indirectly do so by starting wildfires that help to maintain healthy ecosystems.
Place the jumbled steps of muscle contraction in proper order
Below are the steps of muscle contraction in the correct order:
The nervous system sends a signal, called an action potential, down a motor neuron.Others are:
The action potential causes the release of a neurotransmitter called acetylcholine (ACh) into the neuromuscular junction.ACh binds to receptors on the muscle fiber's membrane, which opens ion channels that allow sodium (Na+) ions to enter the cell.The influx of sodium ions creates an electrical current that spreads throughout the muscle fiber, causing it to depolarize.The depolarization triggers the release of calcium (Ca2+) ions from the sarcoplasmic reticulum (SR) within the muscle fiber.The calcium ions bind to troponin, which causes tropomyosin to move away from the myosin binding site on actin.Myosin heads bind to the exposed binding sites on actin, forming cross-bridges.The myosin heads pivot, pulling the actin filaments towards the center of the sarcomere (power stroke).ATP binds to the myosin head, causing it to detach from the actin filament.The process of myosin binding, power stroke, and detachment continues as long as calcium ions are present and ATP is available.When the action potential ceases, the muscle fiber repolarizes and calcium ions are actively transported back into the SR, causing the tropomyosin to block the myosin binding sites again.Lastly, The muscle fiber relaxes as the tension in the sarcomere decreases.
