10%
Explanation:
Only 10% of the energy absorbed by plants from the sun is passed to primary producers and converted to biomass. Similarly, only 10% of the energy fro primary producers is passed to secondary producers, and this continues up teh chain to Quaternary consumers. This is why energy of an ecosystem is represented as a pyramid (tapering at the top). Transfer of energy up an ecosystem is very inefficient with most of the energy lost to the environment as heat during the transfer. In this case, the oak tree is a primary producer which represents the base of the energy pyramid.

The addition of another person at each end of the rope does not affect the results of the tug of war.
The addition of another man at each end of the rope does not affect the results of the tug of war because the forces exerted by each individual are independent of each other.
In a tug of war, the force applied by each person depends on their individual strength and the technique used to pull the rope.
The total force exerted on the rope is the sum of the individual forces, and it remains the same regardless of the number of people at each end.

Explanation:
Homeostasis is defined as the ability of an organism which can maintain a stable, and constant internal (temperature) environment in the body.
If our body gets too high or too low temperature sensors present in the periphery and brain tells the temperature regulation center of our brain in a region is known as hypothalamus that our body temperature has strayed from its point.
because it is a different planet in our solar system. also it is suitable for humans
