habitat
An organism's specific function, or job, in the ecosystem is its

niche
habitat
adaptation
The transfer of energy and nutrients through a community is called
food chain
food web
producer
consumer
Any animal that hunts and eats other animals is called a
prey
predator
carnivore
omnivore
The animals that a predator hunts are called
individuals
food chain
host
prey
Several food chains linked together are called
symbiosis
adaptations
niche
food webs
Two or more organisms trying to use the same resources are called
competition
niche

adaptation
Any special characteristics or skills that help living things survive in their environment are
niches
competitions

Whenever two species interact with each other over a long period of time, it is called
adaptation
competition
learned behavior
symbiosis
Any organism that lives on or inside another organism and takes food from that organism, it is called
host
parasite
competition
adaptation
The plant or animal that a parasite lives on or in is a
consumer
scavenger

A tropical rainforest would be an example of
a small ecosystem
a large ecosystem
a colder place
a very dry place
A rotting tree stump in the forest would be an example of
a place you would find consumers
a place scavengers hang out
an example of a small ecosystem
not an example of an ecosystem
Example of living things in an ecosystem are
plants
animals
bacteria
water
Examples of nonliving things in an ecosystem would be
sun
soil
water
bacteria
Hawks and owls both eat mice and live in similar places. But hawks hunt by day and owls by night. This is an example of
how a niche is unique to a population
how symbiosis is caused from a relationship between two organisms
how competition causes one population to leave
how carnivores are different from herbivores
What things are needed for photosynthesis to happen?
oxygen
carbon dioxide
sunlight
water
Where do producers get their energy from?
other producers
the sun
consumers
decomposers
Where do consumers get their energy (food) from?
consumers and/or producers
decomposers
scavengers
the sun
What breaks down dead things and waste in an ecosystem?
decomposers
producers
consumers
scavengers
What group eats only other consumers?
carnivores
herbivores
omnivores
scavengers
What group eats only plants?
carnivores
herbivores
omnivores
scavengers
What group eats both plants and animals?
carnivores
herbivores
omnivores
scavengers
What group eats things that have already died?
carnivores
herbivores
omnivores
scavengers
Why are scavengers beneficial to an ecosystem?
They keep the populations small.
They eat only diseased things.
They keep the ecosystem clean.
They break down waste, which adds nutrients back into the environment.
Why are decomposers beneficial to an ecosystem?
They provide food for consumers.
They keep the ecosystem clean.
They break down waste, which adds nutrients back into the environment.
They keep the predator / prey relationship balanced.
Which types of living organisms are often the first two links of a food chain?
producer
omnivore
carnivore
herbivore
Check all that are true about how changing one part of a food web affects other organisms.
If a predator population decreases, the prey population could increase.
If a prey population increases, the predator population might decrease.
If a predator population increases, the prey population could increase.
If a prey population decreases, the predator population might decrease.
What are two things that an energy pyramid shows?
which animals will be migrating
how energy moves through one food chain
the four basic needs of all living things
the sun provides energy for all living things
Keeping the ecosystem balanced by forcing groups to move or die is a benefit of
migration
hibernation
symbiosis
competition
The four basic needs of all living things are
food
water
protection from consumers
shelter
protection from producers
Three reasons why an animal may migrate are
to avoid weather that is too hot or too cold
to be safe from other animals
to reproduce or to raise their young
to search for food
What are four things that happen during hibernation?
the animal sleeps through winter
the body temperature rises
the body temperature drops
little energy is used during the winter
the breathing and heart rate slow down
When a relationship between two organisms helps one partner and hurts another, it is called
parasitism
commensalism
mutualism
When a relationship between two organisms is beneficial to both, it is called
parasitism
mutualism
commensalism
When a relationship between two organisms helps one partner and neither helps nor harms the other, it is called
parasitism
mutualism
commensalism
Fleas causing an animal to itch but the flea gets the blood of the animal is an example of
parasitism
mutualism
commensalism
Bees getting food by collecting pollen and also moving pollen to another flower, which helps pollinate the new flower is an example of
parasitism
mutualism
commensalism
Tropical orchids growing on upper limbs of trees; the tree supports the orchid and lets it get sunlight, but it doesn't do anything for the tree is an example of
parasitism
mutualism
commensalism
God-given basic knowledge and skills that an animal needs for survival would be
learned behaviors
symbiosis
instinct
niche
Behaviors that cannot be inherited are called
adaptations
learned behaviors
instinct
symbiosis
Understanding the interactions in ecosystems allows a Christian to exercise good dominion by
knowing what kinds of food to eat
knowing whether hunting is okay
living in habitats without destroying them
only growing certain crops
