Birds do not directly obtain energy from the sun. Like all animals, birds acquire energy by consuming food. However, the energy contained in their food ultimately originates from the sun. Through photosynthesis, plants convert solar energy into chemical energy, which is then transferred through the food chain. Therefore, it could be said that all animals, including birds, ultimately depend on the sun for their energy, but the percentage of this energy cannot be quantified accurately.
do they get 4%?
There is no specific or fixed percentage of energy that birds or any other animals get from the sun. The energy obtained by birds is ultimately derived from the food they consume, which is derived from plants or other animals in the food chain. The energy in these organisms can be traced back to the sun's energy, as it is the primary source that fuels photosynthesis. However, quantifying the exact proportion of energy that can be attributed to the sun is difficult and varies depending on the specific ecosystem and food sources.
