Plants
View source
What type of teeth do herbivorous organisms have?
Large flat teeth
for
grinding
View source
What additional teeth do omnivorous animals possess?
Sharp
canine incisors
View source
Why is understanding dentition important for studying extinct species?
It reveals their
dietary habits

Jaw-like
mouthparts and
tube mouthparts
View source
What do jaw-like mouthparts in insects help with?
Biting
and
chewing
View source
What do tube mouthparts in aphids allow them to do?
Suck sap from
plants
View source
What adaptations do plants have to resist herbivory?
Spines
,
toxins
, and stinging parts
View source
How do some herbivores overcome plant defenses?
By producing saliva that blocks
toxins
View source
What adaptations do predators have for catching prey?
Chemical
,
physical
, and
behavioral
adaptations
View source
How do prey avoid being eaten?
Through
chemical
, physical, and
behavioral
adaptations
View source
How do behavioral adaptations evolve compared to chemical adaptations?
Behavioral adaptations evolve
faster
View source
What is the challenge for plants in the rainforest?
Competition for light with other
species
View source
How do trees adapt to compete for light?
By
growing
very
tall
View source
What adaptation do vines use to compete for light?
They grow through other trees for support
View source
What do epiphytes do to capture light?
Grow on tree trunks where light is
abundant
View source
What do strangler figs do to their host trees?
They
outcompete
and
eventually
kill
them
View source
How do shade-tolerant shrubs survive in low light?
They have special
adaptations
for low light
View source
What is an ecological niche?
The role of an
organism
in its environment
View source
What is the fundamental niche?
All
possible
conditions for survival
View source
What does the realized niche represent?
The
fundamental niche
minus
competition effects
View source
How does competition affect an organism's realized niche?
It
reduces
the
size
of
the
realized
niche
View source
What happens if a species is outcompeted in its entire fundamental niche?
It gets
excluded
from the ecosystem
View source
How does climate change affect species' niches?
It can lead to
exclusion
from habitats
View source
What is the impact of overlapping niches on competition?
One
species
may outcompete the other
