Combine the given two facts to write a concluding fact. Note that there should be some parts of the first and second facts that are not mentioned in this conclusion fact. Your combined fact should be the result of a chain between the two facts. Chains form when two facts connect together to produce a concluding fact. An example of a chain is: "pesticides cause pollution" (fact1) + "pollution can harm animals" (fact2) → "pesticides can harm animals" (conclusion fact). Parts of the concluding fact overlap with the first and the second fact. To construct such a  concluding fact, a useful way is to borrow the subject from one fact and the ending conclusions from another fact.

Input: Consider Input: Fact 1: Carbon cycles quickly between organisms and the atmosphere. 
Fact 2: Deforestation also disrupts the Carbon Cycle.

Output: Deforestation disrupts the cycle between organisms and the atmosphere.


Input: Consider Input: Fact 1: irradiating food can be used to kill existing microorganisms in the food. 
Fact 2: Irradiation causes chemical changes.

Output: chemical changes can be used to kill existing microorganisms in the food.


Input: Consider Input: Fact 1: Mutualism is a symbiotic relationship in which both species benefit. 
Fact 2: Out of the 8,400,000 different species of living beings, there are 400,000 human species.
