Question:Could you help me w/ this? I'm confused!
List a predominant abiotic factor in each of the following biomes: temperate deciduous forest, boreal coniferous forest, desert, tundra, tropical rainforest, and savanna.
Thanks- i'm trying to grasp this concept!
Answers:1. Available energy, i.e., sunshine
2. Available water
3. Available inorganic nutrients, e.g, iron, phosphorus, fixed nitrogen.
The availability of these is somewhat different depending on which biome you choose.
The following biome is characterized by having a warm, humid climate and contains the world's largest area of biodiversity: (4 points)
D) Rain forest
In any food chain, the total amount of energy always __________. (4 points)
C) stays the same
D) decreases then increases
Answers:Question 1 - answer D. Regions where they receive higher amount of solar energy, near the equator and between the tropics tend to be a higher biodiversity. Certainly the plants tend to have higher gross primary productivity and thus encourage other species (herbivores, carnivores, omnivores) to ecological succession.
Question 9 - answer B. Any food that is enjoyed by animals, some of this is eliminated in the form of heat, and the higher the hierarchical level within the food chain, the lower the amount of energy available.
Question:1.) Which explains why secondary sucession generally occurs more rapidly in an area then does primary sucession?
a. Average precipitation is higher
b. Moderate climatic conditions exist
c. Pioneer species are microscopic
d. Soil Formation has already occured
2. Conifer trees dominate boreal forests rather than tundra because of ______
a. A lack of permanently frozen soil
b. direct rays of light hitting the biome
c. mild climatic and weather conditions
the absence of better adapted trees
3. Which defines a biome as a desert?
a. A region of few or no trees
b. Annual rainfall less then 10cm/yr
c. Area with no organic matter in soil
d. rate of evaporation higher than precipitation.
4. Which explains why few animal species live in a fast-flowing river?
a. Cold water lowers dissolved oxygen levels.
b. Currents prevent accumulation of most organic matter
c. Few animals are adapted to withstand high-speed water.
d. Frothing water reflects sunlight away from autotrophs
5. Which ecosystem has the greatest bipdiversity?
6. Which zone would support the gratest variety of coral reef ecosystems?
a. abyssal zone
b. aphotic zone
c. intertidal zone
d. photic zone
Thank you soooo much.... have a great day!!!! <3
Question:HELP!!!! I have a report i am supposed to do and can't find a food chain with 8 organisms in the Taiga (biome)!!!!

Biomes Savanna | Biology | Ecology :Purchase DVD here www.greatpacificmedia.com Segment from the program: Terrestrial Biomes: Deserts, Grasslands, and Forests. DVD Description Our Terrestrial Biomes DVD starts by introducing the four requirements of life - nutrients, energy, liquid water and temperatures appropriate for carrying out life processes and then goes on to explain the factors such as latitude, proximity to oceans, and elevation, that affect climate. Climates relationship to the type of vegetation found in a biome is then explained before introducing students to the major terrestrial biomes including tropical rainforests, temperate rainforests, deciduous forests, savannas, grasslands, chaparrals, taiga, tundra and deserts.
