Biology B1 Decaying Flashcards
Relationship between living things and materials
Remove materials from envir
growth + other processes
materials returned environment
waste materials
or die and decay
What do materials break down?
digested (broken down) by microorganisms
In what conditions will microorganisms be more active?
Warm
Watery (moist)
Full of oxygen (aerobic)
What do microorganisms release when they decay stuff?
Substances that plants need to grow
What leads to a stable community?
Processes that remove materials
balanced
processes that return materials
materials constantly cycled
What is the carbon cycle?
Constant cycling of carbon
When happens in carbon cycle? (There’s loads so I’ll try to summarize hopefully lol)
C into plants (photosynthesis) C --> CO2 out of plants (respiration) C into animals (animals eat plants) C out of animals (respiration) C out of plants and animals (die) C out of microorganisms (respiration) C out of plants (combustion)
Why are microorganisms important?
decomposing materials
can be used again by plants
What is make up of the body of green plants and algae that is from carbon (from CO2)
Carbohydrates, fats, proteins
Carbon from plants + other animals become which parts of some animals?
part of fats + proteins
make up their bodies
What happens when plants, algae +animals die?
Some microorganisms feed on their bodies
What break down waste products + dead bodies of organisms in ecosystem?
Microorganisms
Detritus feeders
Statement to everything happened at once
Microorganisms + detritus feeders broke down waste products + dead bodies
cycled materials as plant nutrients
energy absorbed by plants + algea has been transferred
What human activities released CO2 into atmosphere?
Combustion of wood
fossil fuel
What ahppened when plants+ animals die
some animals + microorganisms feed on their bodies
