Background

A forest biome is dominated by an abundance of trees, though its overall composition is so diverse that it contains the majority of the terrestrial biodiversity of the world. It includes the subcategories of boreal forests, temperate forests, and tropical forests. These forests are each found at different latitudes and, therefore, experience distinct climatic conditions. A boreal forest, also known as a taiga, is found at the highest latitude of 50 and 60 latitude. It contains the coldest climate with its precipitation occurring primarily in the form of snow. The broadest location of boreal forest can be found in a combination of Alaska, Canada, Scandinavia, and Siberia. Its seasons are divided into short, moist, and moderately warm summers with long, cold, and dry winters. A temperate forest is found at the middle latitudes of 25 and 50 latitude in both hemispheres. It contains four distinct seasons and, thus, is composed primarily of deciduous trees. They can be found mainly in the eastern portion of the United States of America, Canada, and Europe with smaller portions in China and Japan. A tropical forest is found at the lowest latitudes between that of 23.5N (Tropic of Cancer) and 23.5S (Tropic of Capricorn). It does not experience traditional seasons and, instead, has its year divided into the dry season and wet season with the most extreme weather patterns occurring between December to May. They can be found primarily in Central America and Southern America, tough there are additional portions in Western Africa, Central Africa, Western India, Southeast Asia, New Guinea, and Australia.
A grassland biome is an open region that is composed of a warm, dry climate and large amounts of grass, hence its namesake. It includes the subcategories of tropical grasslands, also known as savannas, and temperate grasslands. A savanna is classified by its close proximity to the equator and sparse number of trees. This type of biome covers approximately half of the continent of Africa, as well as areas of Australia, India, and Southern America. A temperate grassland is found further from the equator, specifically in areas such as Argentina, Hungary, North America, Russia, South Africa, and Uruguay. They do not have trees or shrubs and receive less precipitation than the savanna. The temperate grassland can be broken down into further subtypes, the two most prominent of which are prairies and steppes. These are distinguishable by their grass types.

Objective

How did the relationship between the two species evolve?
How does the relationship adapt the species to the abiotic environment?
How does the relationship affect the biodiversity of other species within the biome?
Are there are effects of humans on the interaction? Are there any effects of the interaction on humans
each group member is expected to contribute three to five paragraphs on their chosen species
