The loss of arctic sea ice has increased over the last several decades. which of the following is an impact of decreasing sea ice that would reduce biodiversity the most? a. the ice decreases the length of fishing seasons. b. the melting ice provides more open land for plant growth. c. the melting ice means less habitat for some marine species. d. the oil rigs increase temperatures, resulting in species migrations

C. The melting ice means less habitat for some marine species.

Explanation:

The melting of ice of Artic sea ice will lead to the increase in the water levels which will be suitable for the survival of some of the aquatic species like krills, whales and fishes. But the animals which thrive over the frozen ice of Artic sea like penguines, polar bear will not survive.Hence, the diversity of the region will reduce.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.

explanation:

b is dominant over the allele for the white fur.
