A grape is a fruit, botanically a berry, of the deciduous woody vines of the flowering plant genus Vitis. Grapes are a non-climacteric type of fruit, ...
Ecosystem ecology is the integrated study of living and non-living components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals , bedrock , soil , plants , and animals .
Vitis californica, the California wild grape, or Northern California grape, or Pacific grape, is a wild grape species widespread across much of California as well as southwestern Oregon; Vitis coignetiae, the crimson glory vine, a species from East Asia grown as an ornamental plant for its crimson autumn foliage
Bunches of small and often sour but edible purple grapes hang from the vines in autumn, which can be made into wine or jelly. [9] The grapes provide an important food source for a variety of wild animals, especially birds, and the foliage provides thick cover. The grapes are a common sight along the banks of the Sacramento River.
Biotic factors of the ecosystem are living things; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere. Plants allow energy to enter the system through photosynthesis, building up plant tissue.
Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and reproduction. Resources are distinguished as substances or objects in the environment required by one organism and consumed or otherwise made unavailable for use by other organisms.
This list of grape varieties includes cultivated grapes, whether used for wine, or eating as a table grape, fresh or dried (raisin, currant, sultana). For a complete list of all grape species, including those unimportant to agriculture, see Vitis .
On the vine, grapes are organized through systems known as clusters. Grape clusters can vary in compactness which can result in long clusters (resulting in the grapes spreading out) or short clusters (resulting in grapes packed together). [31] In some grape species, clusters ripen collectively, which allows them to be harvested together. [32]
