1.
Anything in an environment that is now OR was once living. (It can grow, react to environmental changes, move nutrients around inside it, reproduce, etc.)
a)
parasite
b)
abiotic factor
c)
biotic factor
d)
predator
2.
Anything in an environment that is not living - and it never has been. These factors could be natural or man-made.
a)
abiotic factor
b)
habitat
c)
species
d)
biotic factor
3.
An individual living thing. (One biotic factor.) Smallest unit of organization in environments.
a)
abiotic factor
b)
organism
c)
population
d)
ecosystem
4.
All the members of a species in a certain area. (How many organisms of one species in an area.) It doesn't matter how large of an area you refer to, as long as you define where it is.
a)
population
b)
community
c)
abiotic factor
d)
ecosystem
5.
All the living things in a certain area. OR All the biotic factors in an area. OR All the populations in an area.
a)
organism
b)
ecosystem
c)
habitat
d)
community
6.
All the living and non-living things in a certain area. OR All the biotic & abiotic factors in an area. Remember that these factors will interact with each other.
a)
species
b)
ecosystem
c)
population
d)
organsim
7.
A type of interaction between members of a community. This can occur within one species, or between members of multiple species. It occurs because there are limited resources (food, water, shelter, mates, territory...) available.
a)
parasitism
b)
predation
c)
competition
d)
commensalism
8.
A type of interaction between members of a community. This typically occurs between members of two or more species. It is hunting with the intent to kill and eat.
a)
symbiosis
b)
predation
c)
commensalism
d)
mutualism
9.
The hunter in the predation relationship. *If you are eating plants, you cannot be one of these - because you're not HUNTING plants!
a)
host
b)
prey
c)
parasite
d)
predator
10.
The animal that is the food source in a predation relationship.
a)
prey
b)
predator
c)
parasite
d)
host
11.
A type of interaction between members of a community. This must occur between members of two or more species who are 'living together' in a close relationship. At least one organism will always benefit.
a)
symbiosis
b)
predation
c)
population
d)
competition
12.
A type of symbiotic relationship in which both species benefit. It is good for everyone involved. Ex: a human and a pet dog
a)
commensalism
b)
predation
c)
mutualism
d)
community
13.
A type of symbiotic relationship in which one species benefits and the other is unaffected. Ex: barnacles on a turtle
a)
mutualism
b)
habitat
c)
species
d)
commensalism
14.
A type of symbiotic relationship in which one species benefits and the other is harmed. Ex: flea and a dog
a)
commensalism
b)
parasitism
c)
ecosystem
d)
predation
15.
An organism that lives in or on another organism, usually harming it by taking some nutrients. This does NOT "want" to kill the organism it lives on, though!
a)
adaptation
b)
parasite
c)
prey
d)
host
16.
An organism that is lived on or in by another. It may pick up a disease or be harmed by that organism.
a)
parasite
b)
predator
c)
host
d)
abiotic factor
17.
A physical or behavioral "trait" that ideally helps a species live well in its environment.
a)
adaptation
b)
biotic factor
c)
symbiosis
d)
population
18.
A group of organisms that are all physically similar to one another. They should be able to reproduce and create offspring that also have those same features.
a)
abiotic factor
b)
organism
c)
predator
d)
species
19.
The place that provides the necessary resources (like food, water, and shelter) for an organism to live. There are usually many of these within each ecosystem.
a)
host
b)
habitat
c)
abiotic factor
d)
mutualism
