Summary Introduction
Introduction:
North Americais the 3rd largest continent of the world's continents. Birds are warm-blooded vertebrate animals. They are placed in Chordata (Phylum) because they have a backbone. They have feathers, wings, and bills. The abundance of the species of birds depends on the food availability and environmental conditions.

Areas with very low precipitation and very high temperatures that are found in Northern Africa and the Western United States are known as:
Tundras.
Grasslands.
Rainforests.
Deserts.
There are many theories that explain why there is higher species richness in the tropical rainforest than the temperate forests. Provide two biotic factors and two abiotic factors explanation.
General Patterns Found Across All Biomes
Disturbance is important in determining the set of species found in an area. Naturally, broadleaf trees will
replace longleaf pine trees, changing the forest from coniferous to deciduous. However, fire removes the
broadleaf species, maintaining the coniferous forest. Before agriculture, the southeastern United States
was dominated by longleaf pine, but now broadleaf trees are found where the great coniferous forests once
grew. From this change in forest species, what do you know has happened to the frequency of fire in the
southeastern United States?
There are more forest fires in the southern United States now then there were in the past.
There are fewer forest fires in the southern United States now then there were in the past.

- Fire creates disturbance in the temperate coniferous forest of the Pacific Northwest. Prior to the early 1900s, patchy, moderately intense, and moderately frequent fires created intermediate amounts of disturbance. Following the early 1900s, a policy of fire suppression greatly reduced fires, creating low disturbance. Today, hotter, drier, longer summers are creating extremely large, intense, and frequent fires, which cause severe disturbance. Which of the following most accurately describes how these levels of disturbance affect species diversity? O Low disturbance allows for the greatest species diversity, because all the organisms are allowed to thrive. Severe disturbance allows for the greatest species diversity, because it facilitates colonization by r-selected species. Moderate disturbance allows for the greatest diversity, because it allows both early and late successional species to exist within an ecosystem. Disturbance does not generally affect species richness. Severe…arrow_forwardWhich of the following patterns best describes how species richness changes from the arctic to the tropics? Species richness increases from the arctic to the tropics O Species richness remains the same from the acrtic to the tropics Species richness decreases from the arctic to the tropics Species richness increases, then decreases from the arctic to the tropics O None of thesearrow_forwardDesert ecosystems are fragile for which of the following two reasons? Frequent wildfire and flooding Rapid nutrient cycling and frost damage Slow plant growth and low species diversity Overpopulation of predator species and drought Off-road vehicle traffic and deep, organic soilsarrow_forward
- Temperate grasslands have very seasonal temperature and rainfall. Summer can be hot and a bit wet, while winters can be cold and dry. Because of these conditions, you would expect temperate grassland species to have.. Narrow fundamental niches Wide fundamental nichesarrow_forwardBiologists have observed much more similarity in species composition among boreal forests and among areas of tundra in Eurasia and North American than among areas of tropical rain forests or among Mediterranean woodlands around the globe. Can you offer an explanation of this contrast based on the global distribution of these biomes?arrow_forwardWhat is the relationship between a pioneer species and primary succession? A pioneer species is an invasive species that causes areas to experience primary succession. There is not a relationship between a pioneer species and primary succession. The pioneer species only occurs in areas of secondary succession. A pioneer species is important in an area of primary succession because it can grow and thrive in areas where most other species cannot. A pioneer species only inhabits areas of primary succession.arrow_forward

Yellow-headed blackbirds can nest only in the middle of marshes, regardless of the presence of red-winged blackbirds, because they require wetter habitat. Based on this, which of the following statements are true? Select all that apply. The realized niches of the two species differ. The fundamental niche of red-winged blackbirds is larger than its realized niche. The fundamental niche of red-winged blackbirds is larger than the fundamental niche of yellow-headed blackbirds. O The fundamental and the realized niches of red-winged blackbirds are the same. The fundamental and the realized niches of yellow-headed blackbirds are the same.arrow_forward
