Cycles
What are the four cycles in chapter 4?
Water, Oxygen and Carbon, Nitrogen, and Phosphorous
The way something lives in their habitat. Their role in the habitat.
What is a Niche
When 2 organisms go head to head for resources (food, water, shelter) Both organisms are harmed by the interaction (- -)
What is Competition
A biome that gets less than 25cm of rain a year. Temps change dramatically from scorching daytime temps to cold nights. Include organisms such as cacti, reptiles, and small rodents
Desert
A factor that limits the growth of a population
What is Limiting Factor
What are the stages of the water cycle?
Evaporation, Condensation, Precipitation, Runoff, Groundwater, Transpiration (water existing in plant leaves)
Plankton->Jellyfish->Fish->Shark
Tertiary Consumer
What is Mutualism?
When both organisms benefit from their interaction (+ +)
This Biome has permafrost year-round with little vegetation except for hardy plants like lichens. There are few trees and precipitation varies from a few inches to several feed of snow
Tundra
The number of same individuals in a certain amount of space is known as this
What is Population density
What are the stages of the Oxygen and Carbon cycle?
Living things take in Oxygen and expel Carbon Dioxide during cellular respiration. Plants also expel Oxygen during photosynthesis. Oxygen from the air dissolves in water. Carbon Dioxide also enters the atmosphere through decomposition and some gets trapped underground and turned into fossil fuels
The number of species (species richness) in an area
What is Biodiversity
When one organism depends on another for survival. One benefits and the other is harmed from their interaction (- +)
What is Parasitism
Evergreens like firs, hemlocks, and redwoods live in this Biome that experiences only 2 seasons each year. The large trees change the soil and block out light for other plants. Animals like moose, wolverines, elk and rabbits live here.
Coniferous Forest
The maximum number in a population that an area can sustain is known as this
What is Carrying capacity
What are the steps of the Nitrogen cycle?
1.Nitrogen Fixation in plant roots bacteria in soil 2.Nitrifying bacteria in soil (convert N2 to NH3), 3.Assimilation (used by plants), 4.Denitrification (reenters atmosphere), 5.Animals and people get nitrogen from plants, 6.Animals excrete nitrogen in metabolic waste, 7.Some atmospheric nitrogen fixed as nitrate during lightning strikes
AKA Consumers. They find their food elsewhere and consume the producers
What are Heterotrophs
What is Commensalism?
One organism benefits and the other is neither helped nor harmed from their interaction (+ 0)
Trees such as oak, birch, ash, and maple grow in this Biome in temperate zones. It receives moderate rainfall and experiences all four seasons
Deciduous Forest
The movements and interactions of the matter in the biosphere, geosphere, and atmosphere are collectively known as this
What is the Biogeochemical cycle
What are the steps of the Phosphorous Cycle?
1.Weathering events cause rock to release phosphates 2.Animals eat plants and excrete waste or die and release phosphates into the soil 3.Bacteria in the soil break down phosphates through mineralization 4. Phosphates are distributes throughout soil and water and absorbed by plants
Create a food web including a Lion, Savanna grasses, Zebra, and Cheetah
One organism is harmed while the other is unaffected from their interaction. (- 0)
What is Amensalism
This Biome receives moderate precipitation. With cool, wet winters and hot, dry summers, droughts and fires are common. Tough flora and fauna live here like scrub, thorn bushes, deer, and antelope. 20% of all plant species live here
Chaparral
Stable, long-lived species that mark the end of succession are known as this
What are Climax species
