Why are niches important to
ecosystems?

Answers

Answer:

Ecological niches allow species to exist in their environment. Under the right conditions, the species will thrive and play a unique role. Without the ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.

If two species occupied the same niche, they would be competing for the exact same resources. The competitive exclusion principle states that one of the species would drive the other to extinction.

The polysaccharide that is responsible for the strong structural nature of plant cell walls is

Answers

Plant cells are surrounded by a tough extracellular matrix in the form of a cell wall, which is responsible for many of the unique features of a plant's life style. The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides. In secondary cell walls, lignin may be deposited. A cortical array of microtubules can determine the orientation of newly deposited cellulose microfibrils, which in turn determines directional cell expansion and therefore the final shape of the cell and, ultimately, of the plant as a whole.

The polysaccharide that is responsible for the strong structural nature of cell walls of plants is cellulose.

The cellulose is an organic molecule that is made up of several units of glucose monomer. The cellulose which make up a large percentage of plant cell walls are composed of a network of several units of glucose monomer that are tightly linked together.

The cellulose, as well as lignin and hemicellulose, which constitutes the tensile fibers in the cell walls of plants, is the polysaccharide responsible for the strong structural nature of plant cell walls.
