What are forms of nitrogen that are unable by humans?
Nitrogen gas (N2) in our atmosphere is an example of a form of nitrogen that humans cannot directly use. Additionally, nitrate (NO3-) in soils is not directly usable by humans and must first be converted by plants into a more bioavailable form of nitrogen.
Can humans break down starch and convert it into energy for their bodies?
Yes, humans can break down starch into glucose through the process of digestion and convert it into energy for their bodies through cellular respiration.
Do all humans need essential nitrate?
No, not all humans need essential nitrate. Nitrate is a type of nitrogen that is essential for plant growth but is not required for humans to consume directly. However, nitrate can be converted to nitric oxide in the body, which may have important health benefits.
Which organ system in humans in most directly involved in the transport of oxygen?
pulmonary - lungs -- circulatory helps transport as well.
Do humans absorb oxygen through the skin?
No, humans do not absorb oxygen through the skin in any significant amount. The primary way we obtain oxygen is through breathing, where it enters our lungs and is then transported by our blood to cells throughout the body.
How do tapeworms perform respiration?
Tapeworms do not have a respiratory system like humans. Instead, they absorb oxygen and nutrients directly through their skin as they live inside the intestines of their host. This is possible due to their flat, ribbon-like body structure and their specialized surface adaptations.
How do humans gain energy from plants directly and indirectly?
Humans gain energy directly from plants by eating the plants themselves in the form of fruits, vegetables, and grains. We gain energy from them indirectly by eating the meat of animals that eat plants.
Oxygen comes into the body through the what?
Oxygen enters the body through the respiratory system, specifically through the process of inhalation. It is taken in through the nose or mouth, travels down the trachea, and enters the lungs where it is exchanged with carbon dioxide.
How can humans change the surface of earth?
Humans can change the surface of the Earth through activities like deforestation, urbanization, mining, and agriculture. These activities can alter landscapes, impact biodiversity, and contribute to environmental degradation. It's important to practice sustainable land management and conservation efforts to minimize negative impacts on the Earth's surface.
How is carbon exchanged between humans and plants?
carbon is released by the human which is enhaled by the human n there fore the cycle moves on
How do humans benefit from the stage of the water cycle when water on the surface sinks deep into the ground?
The water is cleaned as it is filtered through rocks and soil.

The water is cleaned as it is filtered through rocks and soil.
Where does the exchange of oxygenfood nutrients and waste materials take place?
You don't specify which organism you are asking about, but I assume you mean in humans. These processes happen all over the body between the blood capillaries and the cells. If you mean exchange with the outside world, then oxygen is exchanged in the lungs, food nutrients in the small intestine, and nitrogenous waste in the kidneys. However, waste carbon dioxide is exchanged through the lungs and other wastes through the skin.
Why do humans have flat faces?
Humans have flat faces because it allows for better communication through facial expressions and speech, as well as providing a larger surface area for sensory organs like the eyes and nose.
What is another name for the dorsal surface?
another name for the dorsal surface in humans is posterior surface and for animals it is superior surface
Do human change Earth's surface?
Humans change the earth's surface by gardening.
In humans the respiratory surface is the walls of the?
