Ecology Exam Review Flashcards
photosynthesis
Is when something sunlight is converted to sugar and oxygen.
cell respiration equation
sugar + oxygen = carbon dioxide + energy+ water
photosynthesis equation
carbon dioxide + water = oxygen + sugar
Atmosphere
layers of gases surrounding the earth for hundreds of kilometres
lithosphere
Earths soild outer layer
hydrosphere
all of earths water above or below the earths surface
biosphere
The place when life can exits with in all the spheres
autotroph
when an organism makes its own food from nutrients
water cycle
clouds - precipitation- ocean lakes rivers- avaporatio- clouds
carbon cycle
CO2 - plants - O2 - consumer- burning fossil fuels- co2
nitrogen cycle
brakes down things which gives them nitric to the grounds.
cell respiration
is when energy is released from food
Herbivore’s
eat plants
omnivores
eats pants and animals
carnivore
eats insects and animals
Primary consumer
herbivores
The following abiotic factors are, except
Water
Moss
Air
Temperature
Moss - living
If a animal got wiped out what would happen to the food chain?
-It would decrease the population
- Over population of species
What is the 10 percent rule?
It means the arrows is pointing to were it it’s energy but, 10% less.
How many trophic levels are there?
4 Tl
A wolf is a good example of?
Carnivores
Producers get there energy from?
The sun
What is the term of area or habit that takes over?
Invasive
The species that interaction in which both organism benefits while the other remains unaffected is termed?
commensalism
Species interaction in which both species gain benefits.
Mitualism
The maximum number of individuals a population can sustain termed?
Carrying capacity
Abiotic factors in this food web- limiting factors
-Temp
- Light
- Water
Biotic factors in a food web - limiting factors
-Humans
-Deforestation
Carbon Cycle
Consumers , 2 carbon dioxide, photosynithis, plants, soil, fossil fuels, detritus.
Orginsuims like bacteria or mushrooms which break down and recycle nutrince from dead plants and animal material
Decomposers
Orginsums that do not need to eat other organisms to obtain nutirince are?
Autotroph
A biotic or abiotic factor that limits population size
Limiting factors
3 abiotic factors of a terrestrial ecosystem
Water, temp, sunlight
