Which of these is a way climate change positively affects organisms?
a. reduces current food supply
b. provides new habitat
c. reduces habitat area
d. increases ocean acidity

Climate change positively affects organisms by providing them new habitat.

Explanation:

Climate change induces changes in various parameters of an ecosystem like temperature, precipitation, soil properties etc. habitats may undergo changes that make it unsuitable for native organisms to live in.

But this new conditions may be favourable for some other kind of organisms to thrive and flourish.

For example, when temperature of a lake increases due to climate change warm water aquatic organisms find a new habitat in the lake. But this threatens the life of native cold water organisms of the lake.

Thus climate change doesn’t bring any benefits to living world without harming one or the other group of organisms.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
