Biomes 2
This biome is located in the northern hemisphere and is considered to be very cold and dry, due to permanently frozen soil.
What is the Tundra
What are the three main examples of Density-dependent factors and are usually biotic?
What is predators, disease, and competition
Denitrifying bacteria convert nitrate back into atmospheric nitrogen is what process?
Denitrification
Both organisms benefit and sometimes neither species can survive without the other is what.
Mutualism
In a study, a rabbit ate grass that contained 1,700,000 Joules of energy. How much of that energy is actually being transferred to the rabbit?
What is 170,000 Joules of energy.
This biome occurs in temperate and tropical regions, and are covered with grasses that have deep roots, which are well adapted for drought.
What is the Grassland
Limiting factors may cause these two events to organisms
What is death or migration
Nitrogen gas is converted into nitrate and ammonium compounds that are usable by plants is what process?
Nitrogen fixation
Prey animals mimic other species that can be dangerous or tastes bad to avoid being eaten is called what?
Mimicry
Food webs show many overlapping food chains, which is more accurate based off of what?
Many organisms eat or are eaten by many other species
This 12-letter term describes a dual-purpose graph that plots a specific location's average monthly temperature as a line and its average monthly precipitation as a bar.
What is Climatograph
Animals that have low levels of parental care are called?
What is "R" strategists
During this process, plants and animals obtain energy by converting carbohydrates and oxygen into carbon dioxide and water.
What is Cellular Respiration
One species benefits while the other is harmed is called what?
parasitism
Organisms are sorted into this in an energy pyramid based on their feeding relationships.
What are the Trophic Levels
This occurs in areas where no soil exists, such as following glaciation or a lava flow. Wind and rain carry spores of lichens to these areas, which secrete chemicals that break down rock. Lichens decay to add organic matter to the developing soil.
What is primary succession.
The ability to reproduce is called what?
Fecundity
Plants and microorganisms take up the inorganic nitrogen compounds through this process.
What is Assimilation
Heterotrophs depend on what for energy?
What are autotrophs
How are living things organized? (Provide a detailed response.)
What are individual/organism -> population -> community -> ecosystem -> biome -> biosphere? (Definitions are provided.)
Primary successions lead to the development of this term.
What is Climax Communities
This factor affects all populations, and affects the population by temperature, storms, floods and drought, and are considered abiotic.
What is Density-independent.
Useable forms of nitrogen are taken up by plant roots and incorporated into plant proteins goes under what process?
Uptake
A realized niche is the smaller niche an organism occupies because of what?
What is Competition
What is the First Law of Thermodynamics?
Energy cannot be created or destroyed.
