an energy pyramid is a diagram that shows energy gain. true or false?

Answer:

The type of carbon cycling that occurs when stored carbon in organisms is released when they die, and when carbon from dead organisms can be released underground in the form of coal, oil, or natural gas is called the geological carbon cycle. This cycle involves the long-term storage of carbon in rocks and fossil fuels like oil, coal, and natural gas. Carbon is also released back into the atmosphere through various mechanisms such as volcanic eruptions, fires, and burning of fossil fuels.

Explanation:

The carbon cycle can be divided into two main categories: the short-term carbon cycle and the long-term carbon cycle. The short-term carbon cycle involves processes that cycle carbon through the Earth system on roughly annual/decadal timescales. This includes photosynthesis, respiration, and decomposition of organic matter. The long-term carbon cycle takes millions of years to come full circle and involves the movement of carbon between rocks, soil, ocean, and atmosphere through a series of chemical reactions and tectonic activity. Carbon is stored in rocks and fossil fuels like coal, oil, and natural gas for a long time in the geological carbon cycle. Carbon is also released back into the atmosphere through various mechanisms such as volcanic eruptions, fires, and burning of fossil fuels in both short-term and long-term cycles

Answer:

S - Savannas are typically found in tropical or subtropical regions.

S - Savannas tend to have more trees and shrubs.

S - Savanna's climate is drier than that of a grassland.

G - Grasslands are found in temperature regions.

G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.

G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.

B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.

B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.

B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

(Also, A savanna or savannah is a mixed woodland-grassland<---similarity)

Explanation: Just research. I decided to state 3 characteristics for both The Savanna and The Grasslands, and then 3 for "B" (both).

Answer: There are two types of change in matter: physical change and chemical change.

Explanation:

As the names suggest, physical changes never change the identity of the matter, only its size, shape or state. In a physical change, atoms are not rearranged and the matter's physical and chemical properties are unchanged.

Explanation:  Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.

Answer: Respiration inhales oxygen gases and exhales carbon dioxide.

Explanation: Here, Oxygen enters the blood during inhalation, and carbon dioxide leaves during exhalation. This process is called Respiration. Air enters through the nose or mouth and goes through the nostrils, then the pharynx where two tubes are seen one for food and the other for air. From there it goes to the larynx, the voice box. Next air travels to the trachea(the windpipe) from which they get divided into left and right air tubes called bronchi. Smaller bronchi are called bronchioles. These end in tiny air sacs called alveoli. Exchange of gases takes place and revert back.

Here is a possible chat between the hypothalamus and the pineal gland before sleep:

The hormone that the hypothalamus produces that sends signals to the pineal gland to produce melatonin is called melatonin-releasing hormone (MSH). The hypothalamus and the pineal gland work together to regulate sleep-wake cycle.

When it gets dark outside, the hypothalamus releases MSH, which signals the pineal gland to start producing melatonin. Melatonin is a hormone that makes the body feel sleepy. It helps to regulate the body's internal clock and to promote sleep.

Answer:

1. An ecosystem is a system of interactions between living and nonliving things in a particular environment.

2. Some examples of nonliving things in an ecosystem include sunlight, soil, rocks, air, water, and temperature.

3. Factors that could affect the number of organisms in an ecosystem include availability of resources, predation, competition, and environmental changes.

4. Organisms interact in an ecosystem in order to find food, to find mates, to escape predators, and to compete for resources.

5. No, you would not expect to find the same kinds of interactions between organisms in very different ecosystems due to differences in biotic and abiotic factors.

6. It is important to understand feeding relationships in an ecosystem because understanding these relationships gives us insight into the stability, dynamics, and functioning of the overall ecosystem. It can also provide an understanding of how the ecosystem may respond to environmental changes.

During sexual reproduction, several alleles from both parent cells converge.

Whoever possesses a more dominant or recessive gene at the time the daughter cell is being formed will have an impact on the genetic material.

Due to the genetic and phenotypic diversity produced by sexual reproduction, people can choose partners based on whom best exhibits these traits.

Due to the options available to sexually reproducing animals, individuals compete with one another and are typically only able to pass on their genes to offspring who exhibit the desirable qualities.  

Therefore, during sexual reproduction, genetic material affected due to alleles transfer between parents.

Answer:

D: adhesion and cohesion

Explanation:

Water is a chemical liquid substance with unique properties that are responsible for the way it behaves. Cohesion and Adhesion are two of those properties responsible for the sticky nature of water molecules.

Cohesion is the property that makes a water molecule attracted to another water molecule by forming an hydrogen bond with one another, while adhesion is what makes a water molecule attracted to other substances aside water. These properties makes water sticky to itself (cohesive) and other chemical molecules (adhesive).

The orientation of the North Pole changes as follows during the year:

The orientation of the North Pole remains relatively fixed throughout the year. It does not change its position or direction.

The North Pole always points in the same direction in the northern sky, which is towards the North Star or Polaris.

However, the tilt of the Earth's axis in relation to its orbit around the Sun causes the amount of sunlight received by different parts of the Earth to vary throughout the year.

From the diagram of the rock cycle the missing part is ( B ) ; Melting

Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.

Magma is released to the earth surfaces during volcanoes therefore the missing term  in the rock cycle is melting

Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

Negative physical impact on marine life, chemical impact on the water, and transport of native species.

Explanation:

Negative physical impact on marine life:

Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.

Chemical impact on the water:

Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.

Transport of native species:

Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.
