any factors that restrict (limit) a population's size
any nonliving factor in the environment
any living factor in the environment
14
What is an omnivore
The sun
A primary producer
Consumers that eat only plants
Consumers that eat both plants and animals
15
In feeding relationship models like food chains and food webs, the arrow points in the direction of
producers
who is dying
who got eaten
energy flow
16
Introduced species can threaten biodiversity because they can
crowd out native species
cause desertification

decomposer
consumer
autotroph
heterotroph
19
What is the main reason that explains why invasive species are so successful in new ecosystems?
they have no natural predators in the new ecosystem
invasive species usually have low birth rates
they are all omnivores so they can eat anything
they don't compete with other species for food, shelter, or space
20

stored as body tissue
eliminated as heat
25
What is one difference between primary and secondary succession?
primary modifies the environment and secondary doesn't
secondary begins on soil and primary begins on newly exposed surfaces
