There are different trophic levels at each stage. Trophic levels determine the amount of energy at each stage of the food chain. For example, the energy is 100% at the producer (plant), so it's the 1st trophic level, and so on. Energy amounts decrease as you go up a food chain, and you rarely find more than 5 animals in one because there is not enough energy left for the 6th consumer

This is a sample response, so it's 100% correct. Peace!
Answer:
The temperate rain forest.
Explanation:
Temperate rain forests are similar in structure and precipitation amounts to a tropical rain forest. The difference is in the location and temperature of each. Tropical rain forests are located on and near the equator, and are incredibly warm and humid, with large amounts of precipitation. Temperate rain forests are found north of the Tropic of Cancer and have moderate temperature and humidity levels. The way to remember the difference is to notice that Temperate is a combination of 'moderate' and 'temperature' and can be said to mean "moderate temperature". I hope this is the answer you were looking for!
The phase contrast microscope uses out-of-phase and in-phase light rays that produce contrast areas allowing scientists to detect even a minute number of protein molecules and focus on the minute internal structures of a particle.
