Lolium perenne, common name perennial ryegrass, [1] English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world.
[2] [3] It is often called ryegrass, but this term is sometimes used to refer to grasses in other genera. They are characterized by bunch-like growth habits. Lolium is native to Europe , Asia and northern Africa , as well as being cultivated and naturalized in Australia , the Americas , and various oceanic islands.
Lolium temulentum, typically known as darnel, poison darnel, darnel ryegrass or cockle, is an annual plant of the genus Lolium within the family Poaceae. The plant stem can grow up to one meter tall, with inflorescence in the ears and purple grain.
In actuality, however, plants do not absorb all incoming sunlight (due to reflection, respiration requirements of photosynthesis and the need for optimal solar radiation levels) and do not convert all harvested energy into biomass, which results in a maximum overall photosynthetic efficiency of 3 to 6% of total solar radiation.

A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
Leymus arenarius can grow exponentially in terms of height and root development in the presence of nitrogen.L. arenarius is known to take up nitrogen into its root system. . Increasing nitrogen concentrations can promote growth, as over time, the plant mass above the surface may not change, but nitrogen will accumulate in the root syst
Granivorous birds often eat paspalum seeds; the chestnut-breasted munia (Lonchura castaneothorax) readily feeds on the seeds of P. longifolium, for example. The ergot Claviceps paspali is a sac fungus that grows on Paspalum, producing ergot alkaloids and the tremorgen paspalitrem; it causes "paspalum staggers" poisoning in cattle.
