What is the total amount of carbon added to the atmosphere from soil and the burning of fossil fuels?(this is for gizmos lab carbon cycle)

Answers

Answer: When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere.

9.4 gigatons (Gt) of carbon per year from fossil fuels and 7.6 Gt of carbon per year from land-use change, for a total of approximately 17 Gt of carbon added to the atmosphere each year.

What is the total amount of carbon added to the atmosphere from soil and the burning of fossil fuels?

According to the Intergovernmental Panel on Climate Change, the average annual increase in carbon dioxide concentration from 2000 to 2009 was about 1.9 parts per million (ppm) per year, of which about 55% came from the burning of fossil fuels and industrial processes, and about 45% came from land-use change, primarily deforestation.

Thus, in terms of actual amounts, this translates to roughly 9.4 gigatons (Gt) of carbon per year from fossil fuels and 7.6 Gt of carbon per year from land-use change, for a total of approximately 17 Gt of carbon added to the atmosphere each year.

Which of the following is a
process that organisms use
to combine two cells to
create one cell, thus
creating a new organism?
A. Asexual reproduction
B. Sexual reproduction
C. Mitosis
D. Somatic cells

Answers

Answer:

B. Sexual reproduction

Explanation:

Reproduction in living organisms, which is the process of creating new copies of a particular species, can occur asexually or sexually. The asexual method of reproduction involves only one organism however, the sexual reproduction involved two organisms of different sexes (male and female).

In sexual reproduction, the male organism produces male gametes (sperm) while the female organism produces female gamete (egg). These two sex cells or gametes come together in a process called FERTILIZATION to form one new cell called ZYGOTE, which eventually develops into a new organism.

During a chemical reaction, substances (called reactants) are combined to form new substances (called products). Which of the following accurately describes the reactants and the products of a chemical reaction? A. The products contain a different number of atoms than the reactants but have the same properties. B. The number of atoms and the properties are the same in the reactants and the products. C. The products contain the same number of atoms as the reactants but have different properties. D. The number of atoms and the properties are different in the reactants and the products.

Which organisms are producers?
Do all please or some is fine

Answers

Answer: lilypad, grass, & ivy

Explanation:

these all use sunlight to produce their own energy

The primary producer in this case is the basal level green leaves, lotus, and grass, which play the primary role in photosynthesis and food production in the food chain or ecosystem.

What is a producer in the ecosystem?

Producers are the foundation of every ecosystem, as they are responsible for producing the organic matter that is used by other organisms in the food chain. They are able to produce this organic matter by using energy from sunlight or chemical reactions to convert inorganic substances like carbon dioxide and water into organic compounds like sugars and other carbohydrates.

Plants are the most common example of producers in terrestrial ecosystems, as they are able to perform photosynthesis and convert energy from sunlight into food. Algae and other photosynthetic organisms perform a similar role in aquatic ecosystems. Some bacteria are also capable of performing chemosynthesis, which involves using energy from chemical reactions to create organic matter.

Hence, the primary producer in this case is the basal level of green leaves, lotus, and grass, which play the primary role in photosynthesis and food production in the food chain or ecosystem.

Living things are mostly made up of four elements: carbon, hydrogen, nitrogen, and oxygen. Describe how plants and animals obtain these elements.

Answers

Answer:

Explanation:

Animals obtain carbon by eating and gaining nutrients. This gives them carbon. They get hydrogen by water and glucose. They get nitrogen from food.

Animals obtain these essential elements through the consumption of food and water on basis of their mode of nutrition. While plants directly synthesize these elements with the help of the process known as photosynthesis.

What are the roles of these four elements?

Carbon is considered the building block of living creatures. While other elements like oxygen, nitrogen, and hydrogen are also required by these living entities in order to complete their life cycle, perform growth and development, energy synthesis, metabolism, etc.

The process of obtaining these essential elements in plants and animals differs a lot. This is because the mode of nutrition for both living entities varies.

Plant being autotrophs synthesize their food through photosynthesis and takes essential nutrients from the soil. On contrary, animals get these elements by eating other animals or plant-derived products.
