Ambrosia (plant)
Ragweeds are flowering plants in the genus ''Ambrosia'' in the aster family (biology), family, Asteraceae. They are distributed in the tropics, tropical and subtropics, subtropical regions of the Americas, especially North America,''Ambrosia'' Flora of North America. where the origin and center of diversity of the genus are in the southwestern United States and northwestern Mexico. Several species have been introduced species, introduced to the Old World and some have naturalisation (biology), naturalized and have become invasive species. In Europe, this spread is expected to continue, due to ongoing climate change. The name "ragweed" is derived from "ragged" + "weed," coming from the ragged appearance of the plant's leaves.

Flora Of Canada
The flora of Canada is quite diverse, due to the wide range of ecoregions and environmental conditions present in Canada. From the warm, temperate broadleaf forests of southern Ontario to the frigid Arctic plains of Northern Canada, from the wet temperate rainforests of the west coast to the arid deserts, badlands and tundra plains, the biodiversity of Canada's plants is extensive. According to environment Canada the nation of Canada hosts approximately 17,000 identified species of trees, flowers, herbs, ferns, mosses and other flora. About 3,322 species of vascular plants are native to Canada, and about 830 additional non-native species are recorded as established outside cultivation there.

Phytochemical
Phytochemicals are naturally-occurring chemicals present in or extracted from plants. Some phytochemicals are nutrients for the plant, while others are metabolites produced to enhance plant survivability and reproduction. The fields of extracting phytochemicals for manufactured products or applying scientific methods to study phytochemical properties are called ''phytochemistry''. An individual who uses phytochemicals in food chemistry manufacturing or research is a ''phytochemist''. Phytochemicals without a nutrient definition have no confirmed biological activities or proven health benefits when consumed in plant foods. Once phytochemicals in a food enter the digestion process, the fate of individual phytochemicals in the body is unknown due to extensive metabolism of the food in the gastrointestinal tract, producing phytochemical metabolites with different biological properties from those of the parent compound that may have been tested in vitro.

Spharagemon Collare
''Spharagemon collare'', the mottled sand grasshopper, is found in sandy-soiled, grassy areas of northern United States and southern Canada. They are known to be a minor pest of wheat crops; however, populations are rarely large enough to cause appreciable damage. Description Adult Adult mottled sand grasshoppers are light to dark tan with dark brown to black speckles that sometimes appear as bands or stripes. The mottled sand grasshopper relies heavily on its camouflaging colors for protection against predators. Most notably, the rear tibia is orange or red, and the inside of the femur is yellow with four darker bands. The wings extend past the end of the abdomen. The forewing is speckled or banded and varies in color, and the hindwing has wide bands of light yellow and black with a clear wing tip. The mottled sand grasshopper has an enlarged pronotal ridge behind the head that looks like a collar. This species exhibits sexual dimorphism—females are larger than males, with a to ...
