How does thermal energy impact the lower layers of atmosphere?
Answer:
Explanation:
Land and water absorb most of the solar radiation from the sun. Some of this solar energy from land and water is then transferred to the lower atmosphere which is in contact with the continents and oceans. From Land, this occurs mostly as heat energy or infrared radiation. Water usually transfers this energy through the evaporation of water into the atmosphere

11. In the carbon-fixing stage, ATP and NADPH are used to convert CO2 into?
12. What is another name for the Calvin Cycle and why?
Explanation:
G3P
This process is called carbon fixation, because CO2 is “fixed” from its inorganic form into organic molecules. ATP and NADPH, which were made during the light dependent reactions, use their stored energy to convert carbon dioxide into a three-carbon compound called G3P.

2. Write a micro-theme(short paragraph 100-300 words) using and explaining the following terms.
a. "Survival of the fittest"
b. Adaptation
c. Evolution
Answer:
The process through which creatures evolve is known as evolution. Mutations cause genetic variety throughout populations, and the ecosystem works with this diversity to select people who are most suited to their surroundings. Eventually, a species can develop into a plethora of others; as a theory suggests that sapiens started as monkeys but evolved into the humanoid beings that we are today. In biology, adaptation is the procedure where a species fits to its habitat; it is the outcome of natural selection acting on hereditary diversity over numerous generations. Survival the fittest is a saying that suggests the fittest survive, not the weak. This is commonly seen in everyday life, whether with humans, animals, plants, it holds the same meaning. An example would be that a person in better physical and mental health would go farther and live longer than one with weak physical and mental health.
The concept of "survival of the fittest" is a key tenet of evolution, which refers to the idea that individuals with traits that provide them with a competitive advantage in their environment are more likely to survive and reproduce than those without these traits. This process of natural selection leads to the gradual accumulation of beneficial traits in a population, resulting in adaptation and evolution over time.
What is adaptation?Adaptation refers to the process by which organisms develop characteristics that allow them to better survive and reproduce in their environment, such as camouflage or the ability to digest new types of food.
Evolution refers to the broader process of change over time in a population's genetic makeup and physical characteristics, resulting from the interaction between genetic variation, natural selection, and other factors. Together, these concepts help explain how organisms are able to adapt and change over time, resulting in the diversity of life that we see today.
The study of evolution has important implications for understanding the history and development of life on Earth, as well as for addressing modern challenges such as biodiversity loss and climate change.
