Which describes a disruption in the water cycle that could affect photosynthesis?
belka [17]

The right answer is Transpiration.

In plants, plant transpiration is the continuous process caused by the evaporation of water from the leaves (and the corresponding recovery from the roots in the soil).


For large plants and helophytes, it can be very important. On average, a plant loses the equivalent of its weight in water per day. This explains the role played by large plant formations, including forests on the water cycle and climate.

vitfil [10]

Answer:

geographical isolation

Explanation:

Reproductive isolation is a process of evolution that ensures that members of different species are incapable of mating and when they do, such mating do not result into any offspring or leads to the production of invalid offspring.

There are two mechanisms of reproductive isolation:

  • Pre-zygotic mechanisms prevents fertilization between two different species and these include habitat isolation, mating seasons, mechanical isolation, gamete isolation,  geographical isolation and behavioral isolation.
  • Post-zygotic isolation prevents the products of fertilization from becoming valid and this include hybrid inviability, hybrid sterility and hybrid breakdown.

<em>Geographical isolation involves the existence of geographical barriers between two populations such that there cannot be mating between the two. The two populations eventually evolve to become different species.</em>
