Biosphere 2 was an attempt to have humans live within a perfectly closed system, as a model for living on other planets. The first attempt failed because the system began losing CO2, which was chemically reacting with the exposed concrete walls. How would you go about designing a habitat that is a closed system? Explain how matter and energy would flow within the system.​

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
