The primary consumer in a food chain that would receive 10% of the Sun's energy is the A. mouse.
The Elm tree would receive all 100% of the Sun's energy.
The mouse follows because it eats greens, then the snake eats mice.
The hawk as top in the food chain in terms of the energy from the Sun itself.
In June 27, 1954. The world's first power plant was opened. In Obninsk, outside of moscow.
In 1868 a hydro electric power station was designed and built by Lord Armstrong at Cragside, England. It used water from lakes on his estate to power Siemens dynomos. The electricity supplied power to lights, heating, produced hot water, ran an elevator as well as labor-saving devices and farm buildings.
Then in 1870 generators were invented to produce power on a commercial scale for industries.
But then in 1882 in Appleton Wisconsin, US DC power, 12.5 kW. This was the first Edison ydroelectric station. It powered Van Depoele's early electric trolleys later in 1886.
Then in 1882 in New York City - Edison Illuminating Company builds New York's first power plant at the Pearl Street Station.
Because oxygen hogs the electrons it has a slightly NEGATIVE charge.
Answer:
- Transpiration is loss of water vapor from leaves.
- Guard cells regulate whether stomata are open or closed based on availability of water in the plant.
- When stomata are closed, the plant is not able to exchange oxygen and carbon dioxide gas with the atmosphere
Explanation:
The gas exchange of plants is part of the cellular respiration process, where the plants both remove and release gases into the atmosphere. This exchange happens through structures present in the leaves of plants, which are called stomata. Stomata function as doors, if they are closed it is impossible for the plant to promote gas exchange, but if they are open. Transpiration occurs with the release of water vapor through open stomata. It is in this water vapor that the plant releases oxygen into the atmosphere.
The opening and closing of the stoma is a highly regulated process, because opening the stoma makes the plant lose water. In this case, the guard cells are responsible for opening and closing the stoma whenever necessary and the plant has good water levels.
