Chapter 40 1. If you are a biologist interested in working in the tropical rainforest‚ briefly describe a research study you could complete at each level in the biological hierarchy‚ starting from the organismal level to the biosphere. 2. What are the two abiotic variables that dictate type of terrestrial biome? Do aquatic and marine systems rely on the same two variables? Why or why not? 3. Which of the terrestrial biomes is the most vulnerable to anthropogenic (human) influence and why?

energy is the sun. 2. List the biomes of the Earth. A biome is a large naturally occurring community of flora and fauna occupying a major habitat (a forest). The biomes of the Earth include the desert‚ the aquatic‚ the forest‚ the grassland‚ and the tundra. 3. What biome do we live in here in Philadelphia? temperate deciduous forest biome 4. What attributes define a biome? climate and dominant vegetation‚ include grassland‚ tundra‚ desert‚ tropical rainforest‚ and deciduous and coniferous forests

The tropics are the regions between the latitude lines of the Tropic of Cancer and the Tropic of Capricorn (Seidel‚ et.al.‚ 2008). The tropics are warm all year‚ averaging 25 to 28 degrees Celsius‚ as they don’t experience the kind of seasons the rest of the Earth does (Seidel‚ et.al.‚ 2008). The tropical seasons are broken up into the wet season and the

Most of us are not aware that our Malayan Tiger‚ Clouded Leopard (Roy Goh 2011)‚ Pygmy Elephant‚ Sumatran Rhino‚ Orang-Utan and Turtles are in the under-extinction animals category. Malaysian should be grateful for owning these animals in our tropical rainforest. However‚ we destroy the forest‚ hunt these animals and export them to other country. Without realizing it‚ these animals are under extinction. That ’s mean‚ we ’re almost losing them from this world. If we keep ignoring them‚ We might not see

Normal reef temperatures usually range from 17-34°c. The coral reef biome is one of the most important of all marine biomes. It is home to more than 25% of all known marine wildlife‚ even though it only covers o.o1% of the ocean floor. Coral reefs are among some of the world’s richest ecosystems‚ beaten only by tropical rainforests in plant

Located at a biological crossroads‚ species from Central and Northern Europe‚ Central Asia‚ the Middle East and North Africa mingles here with endemics found nowhere else. One of the most biologically rich regions on Earth‚ the Caucasus is among the planet’s 25 most diverse and endangered hotspots. The Caucasus is one

Biotic and Abiotic Factors A savanna grassland is an ecological system with scattered shrubs and isolated trees. The grasslands are found on both sides of the equator between tropical rainforests and desert biomes and have warm temperatures year round. A grassland savanna has a variety of biotic and abiotic components ranging from simple to highly specialized plants and animals and physical characteristics. The biotic components of a savanna grassland are the living organisms that inhabit the area

Introduction A forest is a complex ecosystem which is predominantly composed of trees‚ shrubs and is usually a closed canopy. Forests are storehouses of a large variety of life forms such as plants‚ mammals‚ birds‚ insects and reptiles etc. Also the forests have abundant microorganisms and fungi‚ which do the important work of decomposing dead organic matter thereby enriching the soil. Nearly 4billion hectares of forest cover the earth’s surface‚ roughly 30 percent of its total land area.The forest

Bio Diversity and it’s loss in growth Biodiversity is the degree of variation of life forms within a given species‚ ecosystem‚ biome‚ or an entire planet. Biodiversity is a measure of thehealth of ecosystems. Biodiversity is in part a function of climate. In terrestrial habitats‚ tropical regions are typically rich whereas polar regionssupport fewer species. Rapid environmental changes typically cause mass extinctions. One estimate is that less than 1% of the species that have existed on Earth areextant

Acknowledgement Contents Introduction A savanna‚ or savannah‚ is a grassland ecosystem characterized by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.[1][2][3] The oak savanna is a common type of savanna in the Northern Hemisphere. Some classification systems[which
