Which list contains only abiotic conditions that might be found in a pond ecosystem? *
1 point
Temperature of the water, green plant populations, dissolved minerals in the water
Temperature of the water, dissolved oxygen in the water, dissolved minerals in the water
Bacteria, dissolved minerals in the water, temperature of the water
Dissolved oxygen in the water, fish populations, insect populations

Explanation:

Abiotic conditions strictly comprises on non-living elements. In the first statement, green plant population is mentioned which is a biotic factor.

In the 3rd statement, bacteria are listed which are biotic entities. Their presence suggest the involvement of biogeochemical cycles in the lake, thus, highlighting both biotic and non-biotic conditions.

In the 4th statement, fish and insect population is mentioned which are also biological entities.

Only second statement is correct because it essentially talks about the abiotic conditions such as temperature, dissolved oxygen and dissolved minerals. Although these parameters could affect the life inside the pond (which cannot be exculded in reality); nevertheless, the need of statement is to identify only those parameters which are abiotic.
