Question

which of the following are examples of a negative feedback loops? A. global warming B. a thermostat that controls the heat in your home C. Loss of bioriversity D. fruit ripening E. convection currents F. I dont know yet​

Answer 1

Answer:

C and A

Explanation:

Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.

Answer 2

The following are the examples of negative feedback loops:

A. global warming

C. Loss of biodiversity

• A negative feedback loop is also called as an inhibitory loop.
• It is a kind of self-regulating system.
• It inhibits the future production of output by the system.
• For example, the body reduces manufacturing of some proteins or hormones when their level is too high.
• A thermostat that controls heat, ripening of fruit, and convectional currents are not the examples of a negative feedback loops.
• Global warming is the increase in the green house gases into the atmosphere. Carbon dioxide is one of green house gases. The level of carbon dioxide in the atmosphere can be controlled by the absorption of carbon dioxide gas from the atmosphere by the plants. This process is self regulating. But if plants are removed by deforestation then it will increase the global warming.
• Loss of biodiversity can inhibit the future production of output of the system that is the total number of species that will reduce in future.

Hence, A. global warming, and C. Loss of biodiversity are the correct options.
