Barometer because a barometer is used to measure air pressure which is used especially in forecasting weather hope that helps :)
A baby's immune system is not fully developed until he/she is about six months-old. In the meantime, pregnant mothers pass immunoglobulin antibodies from their bloodstream, through the placenta, and to the fetus. These antibodies are an essential part of the fetus's immune system. They identify and bind to harmful substances, such as bacteria, viruses, and fungi that enter the body. This triggers other immune cells to destroy the foreign substance.
It will be Control. Part of the experiment used to show that the results of an experiment is really due to the conditions being tested.
The energy available for the second-level consumers is <u>4756.5 </u>kilocalories.
A trophic level is a position in the food chain or nutrient cycle of an ecosystem. Based on their eating habits, organisms in a food chain are divided into various levels. The first trophic level is usually occupied by producers that can synthesize their own food.
The efficient energy transfer from one trophic to another is only 10% rest of the energy is lost in the ecosystem. The studies of the transfer of energy in different food chains in a large number of ecosystems have revealed a uniform pattern, which is stated as the 10 percent law by Lindemann. According to this law, only 10 percent of the energy entering a particular trophic level of organisms is available for transfer to the next higher trophic level.
Calculation:
Producers (475650 kilocalories) —> Primary consumers (10% of 475650 = 47565 kilocalories) —> Secondary consumers (10% of 47565 = 4756.5 kilocalories).
So, the energy available for second-level consumers is 4756.5 kilocalories.
