How would the ecosystem’s carrying capacity for a species change, if the species cannot adapt to changes of habitat?
i really need to know about the carrying capacity, because i know what would happen if they can not adapt, they would die.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
