Answer:
Throughout their life cycles, frogs have an important place in the food chain as both predators and prey. As tadpoles, they eat algae, helping regulate blooms and reducing the chances of algal contamination. Frogs are an important source of food for a variety of animals, including birds, fish, monkeys and snakes.

Explanation:
Production. According to the U.S. Energy Information Administration, most of the nation's electricity was generated by natural gas, coal, and nuclear energy in 2018. Electricity is also produced from renewable sources such as hydropower, biomass, wind, geothermal, and solar power.
Conditioned stimulus
Classical conditioning is a learning procedure in which a biologically potent stimulus paired with previously neutral stimulus. This pairing will cause a response that can be the same as the potent stimulus. This is done repeatedly for an organism to elicit a conditioned response to the previously neutral stimulus that was paired to the active stimulus. The dog salivates due to the idea that food is related to the sound of the bell.
The proportion of energy transferred from one trophic level to the next is known as trophic level transfer efficiency or ecological efficiency. The Ten Percent law states that 'net production at one trophic level is generally only 10% of the net production at the preceding trophic level'. In this example, the producer contains 6000 units of energy. 10% of this will be transferred to the primary consumer, i.e. 600 units. In turn, 10% of this energy will be transferred to the secondary consumer i.e. 60 units.
