Draw an example of a food chain.

Herbivores are also called (a) consumers.
What is the primary (1st) source of energy for all living things?
water
air (oxygen)
the sun
electricity

3
Correctly label each trophic level
Which scenario would affect the MOST organisms?
All producers die.
All primary consumers die.
All secondary consumers die.
All apex predators die.
Humans are (a) . They are also called (b) consumers, and are located on the (c) trophic level.

organism
community
The level of organization that includes BOTH biotic and abiotic factors is
A species form that supports the balance in the entire ecosystem.
Keystone Species
Herbivores
Umbrella Species
Predators
How can the removal of a keystone species affect an ecosystem?
It can increase biodiversity.
It can lead to a more stable ecosystem.
It can cause a trophic cascade and disrupt the ecosystem balance.
It has no significant effect.
In biomagnification, the amount of toxin
decreases in concentration along the food chain
remains the same along the food chain
increases along the food chain
In bioaccumulation, the concentration of toxin
increases in the body of the organism.
decreases in the body of the organism.
remains the same in the body of the organism.
