1)What is a trophic level? 2) explain how energy travels through food web ? your response must include the following terms:
Decomposer, producer, primary, consumer , 10%.

3)why is energy reduced at successive trophic levels?

1. The trophic level is something's position in the food chain/food web.

2. Energy travels through out the food chain because all the animals eat each other and take each other's energy. The decomposers are eaten, the producers are eaten, but the primary consumers get all the energy.

3. The energy decreases because each animal decomposes the energy a little, before getting eaten. By the time the food reaches the top of the web, the energy is barely left.

Hope this helps!

increases the risk of extinction 

explanation:

the answer is that if the species suffers from the disease, there is nothing stronger than the others, so it is possible to remove wholeness. an example of this is hunger in irish potatoes, which has a deadly disease bearish part of all potato harvest masses. pretty much ruins the land of crops.

hybridization actually occurs frequently in nature. evolution is derived from the process of hybridization that creates things with different traits. this leads to the species changing and evolution occurring. hope this : )
