ecology Flashcards
domestic pollution-harmful effect
can cause global warming
control measure:domestic pollution
change to renewable forms of energy, eg solar panels
agricultural pollution:harmful effect
can cause eutrophication
control measure:
forestry
only spread fertiliser during dry weather
industrial pollution: harmful effect
can contribute to acidic rain
control measure:industrial
use sulphur free fuels or change to renewable forms of energy
conservation:agriculture
storing slurry in leak proof pits
only spread on land in summer
dont spread fertilisers in wet conditions
growing crops and livestock
fisheries
analysing water supplies
fishing quotes
monitoring of fish stocks
mesh sizes of nets are large to allow younger fish to escape
forestry
tops of trees and branches are converted to sawdust and then to MDF
Felled trees are replaced with young trees for future
effective and rapid action plans for forest fires
pyramids-normal
the number of organisms decrease as you move up the pyramid due to energy loss between trophic levels(TOP IS SMALLER BOTTOM GETS LARGER)
inverted pyramids
begins with producer and ends with consumer
population control
a population comprises all the members of a species living in an area
factors that control populations
competition
predation
parasitism
symbiosis
competition
occurs when organism actively struggle for a resource that is in short supply
consequence: conpetition
number of organism is reduced
plants compete for:
space
light
water
minerals
animals compete for
food
shelter
water
territory
reproductive rights
types of competition
scramble-plants🌱
contest-animals🐾
scramble🌱
all competing organism get some of the resource🌞
contest🐾
a physical contest between 2 organism in which only ONE of them gets the resource🥩
intraspecific competition 🌱
take place between members of the same species
interspecific competition🐾
takes place between members of different species
benefits of competition:
maintains a species at sustainable levels
a driving factor for evolution
techniques to avoid competition:
adaptations
camouflage🫣
protective coats🐑
predation
the catching killing and eating of another organism
🐾->☠️->🥩
predator🐺
organism that catches kills and eats another organism
prey🐁
organism that is eaten by predator
adaptation-prey🐇
long ears-to hear predators🐇
eyes at side of head-wide field vision🐇
powerful hind legs-move quickly🐇
predator adaptations-🐺
excellent vision👁️
strong jaw to chew🦷
sleek to get through ditches🐾
population
organisms of the same species living in the same environment
community
populations of organisms living in same environment
ecosystem
living and nonliving parts of an environment found in a specific location
abiotic factor
sunlight☀️
biotic factors
worms 🪱 frogs 🐸
biosphere
part of the earth that supports life🌎
biome
large region of earth that has a certain climate and certain types of living things
homeostesis allows organisms to
control their temperature 🌡️
control their amount of water 💧
maintain cell functions
environment
the surroundings in which an organism lives
niche
role of an organism
ecology
the study of living organisms and the environment
food chain
sequence of organisms showing the transfer of energy from one to the next
edaphic factor
soil
omnivore
eats plants and animals🌱🥩
contest competition
only one winner
nitrogen fixation
nitrogen->nitrates
what is the ratio of hydrogen atoms to oxygen atoms in a carbohydrate
2:1
structural role of lipids in cells
membranes
metabolic of lipids in cells
energy
eg of fat soluble vitamin
A D E K
eukaryotic
contain nucleus
prokaryotic
no nucleus
eukaryotic
contain nucleus
prokaryotic

stain that can be used for cells
metholine blue🐑
iodine🌱
population
organisms of the same species living in the same environment
community
populations of organisms living in the same environment
ecology
the study of living organisms and the environment
food chain
sequence of organisms showing the transfer of energy from one to the next
edaphic factor
soil
quantative study
measuring
gathering
collecting
observing
the amount of organisms
omnivore
eats 🌱 and 🐑
