4

What determines how populations access energy and matter within a community

interactions

New cards
5

competition

predation

symbiosis

New cards
8

What are the types and results of symbiosis

parasitism- positive/negative

commensalism- postive/neutral

mutualism- positive/positive

New cards
9

What does cooperation or coordination between organisms, populations, and species result in

enhanced movement of matter and energy

New cards
10

What communities are less resilient to changes within the environment

communities with low component parts and little diversity

New cards
11

What can influence the organization of the ecosystem

diversity of species

New cards
12
