one‚ and the entire thing collapses. There really is no “Most Important”. * What is biodiversity? Is it important? Relate biodiversity to the tropic levels. Biodiversity is the variation of taxonomic life forms within a given ecosystem or a biome. It is the measure of health of the biological system to indicate the degree to which the species are diverse and the count of viable versus extinct species. Each level of consumption in a food chain is called a tropic level. More diversity means more

Seas and oceans provide various types of resources to human beings and habitats to numerous species of plants and animals. They play very important roles in the economy of a nation and its people. Still‚ the marine and coastal ecosystems are under severe stress due to human activities. Ocean Resources The ocean is one of Earth ’s most valuable natural resources. It provides food in the form of fish and shellfish—about 200 billion pounds are caught each year. It ’s used for transportation—both travel

1. The science of biogeography is the description of distribution of life and the explanation of this description. The description is based on both time and space. This describes how things look and why they are there. It also looks to answer the question – are these features the same over time? Biogeography arose with the theory that life on earth is a non-random distribution. This is the most important observation leading to the field of biogeography. The study of biogeography includes many other

famed for gold and potatoes‚ which they preserved by mashing. They also carved step-like terraces into the sides of the steep slopes they built their cities on to stop soil from eroding and collapsing underneath them. They had only domesticated the llama‚ and it was for solely food and clothing. The natives in general set fire to the grasslands themselves because it made them lush and green; it attracted herbivores‚ and made hunting much easier for the natives. Back in Europe‚ only nobles were

Temperate Rainforest (Wade et al. 2008). The Valdivian Temperate Rainforest ranges along the Pacific coasts of southern Chile and Argentina in South America‚ between 36 and 47° S latitude. This forest occurs in the temperate broadleaf and mixed forests biome (Perry et al. 2008). The broadleaf evergreen flowering trees that dominate the Valdivian are believed to have evolved in “near complete isolation” from the temperate rainforests of the Northern Hemisphere (DellaSala 2011). Though theses broadleaf species

Their preferred habitats include marine or tropical saltwater within biomes of benthic reef. Odontodactylus scyllarus have been found inside the stomach of yellow fish tuna but other than this they have no other known predators. Thus‚ the peacock mantis shrimp is to be considered a

seasonality migration and aggregation of the poles would be mythical; also would be too cold for reproduction hence no “annual flush of productivity.” In the desert there would be now wet season which is an absolute requirement for terrestrial life in this biome. The earth’s sustainability would be minimal if the axial tilt were nil. Ratification of all earth’s species (besides extremists) would be embedded between approximately 20°N-60°N latitude; temperatures in these areas as follows 20°N latitude 35°C
