The somewhat-predictable series of changes to ecosystems over time is called
(community development / ecological succession / population ecology /
symbiosis development). the first species to colonize barren areas are called
(pioneer / primary / secondary / tolerant) species, and may include lichens and
some grasses.

Ecological succession and pioneer species.

Explanation:

The ecological succession may be defined as the change in the species community with respect to the time. Two main types of succession are primary succession and secondary succession.

The species that occupies the first in the succession is pioneer species. The grasses, lichens can acts as the pioneer species in the primary succession. Secondary succession is faster than primary succession.

Thus, the answer is ecological succession and pioneer species.

mientras se trata la anorexia o la bulimia, es importante buscar ayuda antes que nada. un profesional de la salud mental será el más útil para aquellos que sufren anorexia o bulimia. este es un buen lugar para comenzar, sin embargo, ver a otros profesionales como dietistas registrados, especialistas médicos y dentistas podría ayudar a alguien a recuperarse de un trastorno alimentario. después de la ayuda profesional, o si la ayuda profesional no es una opción, alguien que se recupere de la anorexia o la bulimia debe rodearse de compañeros de apoyo, padres u otros miembros de la familia que también estén comprometidos con el proceso de recuperación.

hope this you! : )

(i popped my answer into google translate so it may be a bit wonky)

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
