<span>Explanation: Oxygen is the more electro-negative of the atoms in the water molecule, so it tends to pull the 'shared' electron more to itself. Thus, the oxygen atom has a greater time-share of all electrons, and therefore the hydrogen atoms are more positive for a partial lack of electrons</span>

Ecosystem is a community or group of living organisms that live in and interact with each other in a specific environment.
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows.

Answer:
promote stomatal closure during drought stress.
Explanation:
Abscisic acid inhibits the growth and stomatal opening, specifically when the plants are exposed to some stress conditions. Abscisic acid also regulates the seed maturation and seed dormancy. ABA concentration in leaves increases multiple folds under drought conditions. Its accumulation in leaves promotes closure of stomata and prevents the water loss by transpiration. ABA is required to restore the turgor pressure under drought conditions by stimulation of stomatal closure.
