B17:OrgansingAnEcosystem Flashcards
(33 cards)
what are the producers of biomass
photosynthetic organisms
examples of photosynthetic organisms
green plants and algae
what can feeding relationships be represented by
food chains
what do all food chains start with
producer
what consumes the producer
primary consumer
what consumes the primary consumer
secondary consumer
what consumes the secondary consumer
tertiary consumer
what are consumers known as
predators
what are the animals being consumed known as
prey
what happens to the number of predators and prey in a stable community
rise and fall in cycle
what materials are constantly recycled to provide resources for organisms
water and carbon
decay definition
rot or decompose through the action of bacteria and fungi
in decay where do mineral ions return to
the soil
what does the water cycle show
how freshwater is available for plants and animals on land before draining into the sea
describe how the mineral ions in a cow’s muscles were once part of a bird
when the bird dies it will have decayed and the minerals will have returned to the soil. The grass will grow on this soil and cows will consume the grass and the minerals will be consumed and stored in the cow’s muscles
explain the role of decomposers in an ecosystem
decomposers break down the waste of dead animals and plants
transpiration
water evaporated from trees
precipitation examples
rain, sleet, snow
how is carbon recycled
through the carbon cycle
what processes return carbon back to the atmosphere
burning of fossil fuels, respiration, the decomposition of dead plants and animals
what form does carbon dioxide return into the atmosphere
as carbon dioxide gas
glucose+oxygen->carbon dioxide+water
respiration
carbon dioxide+water->glucsoe and oxygen
photosynthesis
how carbon is passed from plants to animals
eating
