Answer:
To demonstrate that the inhibition by Janthinobacterium lividum on chytrid found in adult amphibian skin is real, the best experimental design would be take infected amphibians and assign them to two populations. Leave one population alone; inoculate the other with Jl. Measure the rate at which infection proceeds in both populations (option C).
Explanation:
Chytrids -<em>Batrachochytrium dendrobatidis</em>- are a species of pathogenic fungi with affinity for amphibian skin, causing alteration of keratin and damage to the animal body.
The verification that Janthinobacterium lividum is capable of inhibiting amphibian skin chytrids requires the design of an experimental model, the most appropriate being that of an infected amphibian population exposed to the bacteria, while the other (control) is not exposed to J. lividum.
In theory, amphibians in the population exposed to bacteria should decrease chytrid infection, whereas in the normal population the infection would remain the same.
Best way to put is is, Survival of the Fittest.

The answer is A. The natural world
Answer:
Carbon Dioxide / Gas
Explanation:
When carbon is in the atmosphere it is usually in the form of molecules of carbon dioxide that is released by living organisms such as humans, plants, animals etc and it is a gas.
