Question

The ecological impacts of warming are manifold. One response has been to reduce seed production my many plants. An example involving phenology and mutualism for this would be A Warming accelerates the timing of flowering but not the time for arrival by pollinators and thus reduces pollination and subsequent seed production OB. An insect increases its metabolic rate from warming, requiring it to eat more plants, which reduce seed production C. Warming indupes greater water stress in the summer and this reduces productivity and seed production D. All of the above

Answer 1

Seed production of a tree is depends on many metabolic process of tree ,moisture contion, hormone, enzyme activty etc.One of the importent process of tree is transpiration ,which depends on many physical condition of atmosphere (like light. moisture etc) . At the high tempature transpiration rate is increased and tress physiological condition become less moisture that directly effect on seed producton .

So here answer will be option no C . Warming induces greater water stress in the summer and this reduces productivity and seed production.
