Answer 2

1) The food chain contains : ( C )  2 predators , 1 herbivore and 1 producer

2) The continuous decrease in rabbit population will cause decrease in : ( D ) Mountain Lion

3) The amount of available energy : ( D ) decrease because it is released as heat into the environment

4) The statement that describes organisms in the food web is : ( C ) Bacterias are decomposers

In the Food chain we have producers, herbivores, carnivores and tertiary carnivores which are all predators. As the population of the herbivores ( rabbit ) decreases in the food chain the number of the carnivores ( mountain lion ) will also decrease significantly.

Ten ( 10 ) percent of energy is transferred across each trophic level as we go up the food pyramid, because some of the energy contained in each trophic level are lost to the environment as well.

Hence we can conclude that the response to your question is as listed above in the answer.
