What are ecosystems composed of?
Living organisms
and
non-living
elements
Why are ecosystems important for biodiversity?
They support a variety of
species
How do ecosystems contribute to human well-being?
They provide food, water, and
air purification
What are the three categories of biotic components?
Producers
,
consumers
, and
decomposers
What role do producers play in ecosystems?
They create their own food through
photosynthesis
What is the role of consumers in ecosystems?
They obtain energy by eating other
organisms
What do decomposers do in ecosystems?
They break down
dead
organic matter
What are abiotic components in ecosystems?
Non-living
elements
that
influence
ecosystems
What is the role of sunlight in ecosystems?
Provides energy for
photosynthesis
Why is water essential in ecosystems?
It is essential for
hydration
and
nutrient transport
How does temperature affect organisms in ecosystems?
It affects their
metabolic rates
What role does soil play in ecosystems?
Provides
nutrients
and physical support for plants
How do biotic and abiotic components interact?
They ensure the health and sustainability of
ecosystems
What is photosynthesis?
Process where plants convert
sunlight
into food
Write the equation for photosynthesis.

precipitation
What is respiration in ecosystems?
Process where organisms convert
glucose
into energy
What do nutrient cycles do in ecosystems?
They circulate key
elements
needed for life
Name a key nutrient cycle.

cycle
How does carbon cycle through ecosystems?
Moves from
atmosphere
to
plants
, then
animals
What is nitrogen fixation?
Process where
bacteria
convert atmospheric nitrogen
How does phosphorus cycle through ecosystems?
Cycles through
rocks
,
water
,
soil
, and
plants
What is the water cycle's process?
Evaporation
,
condensation
,
precipitation
,
runoff
