Study Guide
Carnivore:
 Animal
that eats only other animals
Prey
 Animal
animal
that is killed and eaten by another
Decomposer
 Organism
that feeds on and breaks down
dead organisms
Ecosystem
 All
the interacting living and nonliving
things in an area
Nutrients
 Things
in food that living things need
Herbivore
 Animal
that eats only plants
Food Chain
 Shows
how living things get food and
energy
Habitat
 Place
where an organism lives
Producer
 Green
plant that makes food
Species
 Group
kind
of living things that are all the same
Adaptations
A
behavior or body part that helps an
organism survive in its habitat
Ecology
 The
study of living and nonliving things
and their interactions
Community
 All
the populations of animals that live in
an area
Endangered
 An
animal species in which very few of its
kind are left
Predator
 An
animal that hunts and eats other
animals
Primary Consumer
 An
animal that gets its energy only from
producers
Variations
 Differences
kind
among animals of the same
Order of Food Chain with
Examples
Producer ->Primary Consumer->Secondary Consumer->Tertiary Consumer
i.e. grass ->
crickets
->
anole
-> Owl
Decomposer
i.e. earthworm and fungi
Examples of Adaptation
 Camouflage
 Mimicry
 Body
parts (like the anole’s toes and tail)
Why might animals need to
adapt its behavior?
 It
needs protection like trying to hide
when it’s getting hunted
 It needs to move like using antennae or
bristles
 Its habitat changed like leaving a place
when there’s no food left
What happens as an energy
pyramid goes from bottom to
top?
 It
gets smaller because the energy is used
up at each level going from the bottom
to the top
Which role in the food chain
puts nutrients back into the soil
for plants?
 decomposers
Producers give their energy to
 Primary
consumers, or herbivores
Why are plants so important in
a food chain?
 They’re
important because all animals eat
plants or other animals that eat plants
