This is the anaphase of mitosis. Anaphase is characterized by the separation of sister chromatids or "pulling away" of the sister chromatids from the metaphase plate to the opposite spindle poles. This is also the phase where chromosomes reach its maximum condensation meaning that the process of the reformation of the nucleus will be shorter and easier.
A field habitat vegetated by grass and other non-woody plants (grasslands) is known as a meadow. They are of ecological benefit as they are open, sunny regions, which fascinate and support fauna and flora that could not survive in other conditions.
In the given case, when a fungus colonizes the meadow and destructs the majority of its vegetation, which comprises species of small shrubs and grasses, then this may result in the decline of herbivore species due to lack of vegetation on which they survive, which will eventually result in the reduction of carnivore species, as they feed on herbivores.
